to measure current in DAQ should we use rms value or DC avereage value

i am taking measurement for single phase or 3 phase voltage and current and display it on front panel voltage measurement is valid but doinh with current measurement i suffer some problem should i take dc avg value or rms value for measurement
when i take dc average value it give result as i want but doing with rms valur it give wrong result according to my circuit sitution. As, we know in ac case rms value is used for measurement but it give wrong result so guide me in this regard
THANK YOU

How to measure current and resistance if i only have DAQ using VB 6 and Measurement Studio

I want to do a remote lab for basic electronic lab. One of the task is to measure current and resistance. How to do it if I only have DAQ card and using Visual Basic 6 and Measurement Studio. Can anyone give me a clue.

If your DAQ device is supported by DAQmx, you can use it with VB6. Here's how: NI-DAQmx Support in Visual Basic 6.0.

I'm working on DC Motor control using DAQ. There is sufficient voltage output from DAQ but not current. What should i do so as to drive the motor

I'm working on DC Motor control using DAQ. There is sufficient voltage output from DAQ but not current. What should i do so as to drive the motor. Could you suggest me appropriate driver IC using which this problem can be solved.

You really should use a DC motor controller to control a DC motor, look at the 754410 IC for a good example. You should be able to interface these to most DAQ devices.

How to measure current and voltage and rpm with daq device

i am measuring current and voltage and am wondering should i use shunt resistors or current sensors hall effect sensors. i have a pci 6221 and a scc-68 breakout box. what specifications or size should the shunt resistor/current sensor be or should i use another device to measure the currrent and voltage. do i need any other safety device between the resistors, current sensors and the scc-68 breakout box when measuring the current and voltage. will the daq card pci 6221 pick up a signal from the resistor. what terminals should the wires from the resistors and current sensors be connected to in the scc-68. i am using a proximity switch to measure rpm of a motor. should the proximity switch be 2 or 3wire connection. should it have an analog or digital connection and is a power supply required to power the proximity switch and should it have an npn or pnp connection

hello,
i was going to use a 20amp 50mv, or a 20amp 100mv current shunt and connect wires directly into the AI input terminals of the scc-68 from the current shunt would these be suitable. would current shunts such as these be suitable to use http://uk.farnell.com/elc/sh10020/shunt-sh10020-20a-100mv-1-class/dp/1319576 or http://uk.farnell.com/datel/3020-01098-0/shunt-50mv-20a/dp/1339338
is it ok to use either a current shunt or should a hall effect sensor be used such as this http://ie.farnell.com/honeywell-s-c/csla2cd/sensor-hall-effect/dp/1082269 . which of them would be more accurate or are both of them fairly accurate.
when i am measuring voltage can i connect two resistors between the positive and negative of the wires going to the battery and connect two wires from either side of the resistor directly into the analog inputs of the scc-68 and measure the 12-15 volts directly would the pci6221 and scc-68 be able to measure the voltage drop across the resistor.
i wanted to measure rpm also does it matter whether the proximity switch has 2 or 3 wires and should it have an analog or digital/frequency output for cponnecting to the scc-68

Writing current to DAQ using AOPoint control

I'm using the CWAOPoint control to write a value of type current to my DAQ card 6024E but I get the following error:
"The specified device does not support the requested action (the driver recognises the device, but the action is inappropriate for the device)"
I had no problem trying to write a voltage value to the same device. Also this worked with the current DAQ and hardware using Labview instead of Measurement Studio. Thanks in advance.

The DAQCard-6024E only supports voltage output and does not support current output. We sell hardware that has the capability of supplying current, such as the NI 6704 output device linked below.

What product(s) should I use to replace Measure?

Hello,
I have a customer who has been using Measure in Excel to communicate with GPIB and possibly DAQ devices. He has been experiencing unstability with Measure and is interested in moving away to another product. Which product(s) would provide the simplest transition? I'm interested in any feedback/ideas you may have.

Go to Solution.

Much of what Measure does today can be pretty easily still accomplished from within Excel using the macro editor although it does require that you write some code to do it instead of using the interactivity that Measure provides. Measure includes a conversion utility that will convert a Measure task to Excel VBA which leverages some of the ActiveX controls from Measurement Studio. Alternatively you could use Excel VBA (or in newer versions of Excel, .NET) directly with our language interfaces for DAQ and GPIB. Again, this would require some amount of programming in Excel. We also have examples which show how to acquire data using LabVIEW and then send that data to a spreadsheet.

Which optimizer hint should i use?

Hi,
I need a query which has a join of 5 different tables which have more than 1 million records each. Which optimizer hint should be best for my query?
Thanks,
Sumit.

Define what is "best" for you. Also, are you using RBO ? Why in first place you need hint ? Is your query performing poorly ? Have you measured current performance ? Most importantly, have you defined your performance goal ?

Differential measurements with a DAQ-500 card

I can't put the differential measurement mode in the Measurement & Automation Explorer. I'm using a DAQ-500 card of NI. Is this because my card doesn't support such measurement mode? There are no jumpers on the card for such a configuration...
Some help on this topic would be useful.

Hello Nicolas,
Thank you for your question regarding a DAQ-500 card. It sounds like you're having problems getting the card to operate in differential mode. Is your device perhaps a PCMCIA DAQCard-500? If so you should be able to use four analog differential inputs. Where is the problem occurring in MAX? Can you right click on the DAQCard-500 in Traditional DAQ Devices >> properties >> AI and then go to mode and select Differential there? If the device is indeed the DAQCard-500 shown here and the problem hasn�t been solved you may want to try to reinstall the card.
Other resources can be found on the ni.com website by clicking the support tab at the top of the home page. Then search from Technical
Resources at the top of the page for your topic. I hope these resources help! Let me know if you need any other support with this issue.

What kind of visa session should i use to communicate with a serial instrument?

I´m trying to communicate with a serial board, i don´t want to use the Measurement and automation explorer, so the resource name should be COM1 instead of ASRL1::INSTR, how can i do this?. What king of session should i use? Waht visa VI should i use to open, close read and write from the srial port?. I want this to work with out MAX. Thanks in advance

The below link dtalks about LabVIEW.ini settings.
Go to this link and scroll down to the entry for serial. It will show you the syntax you need and alos provide another link for more info.
I seem to remeber (not sure) that Visaconfig.ini defines the aliases normally assigned by MAX.

How to measure current on DC servo motor.

Need to measure current on DC servo motor. What is the best way to measure the current on the motor as it moves to position? Using PXI-7344 controller and MID-7654 drive unit.

This is not an easy task. Here are some ideas:
Direct current measurement:
Add shunt resistors into the motor cabling and measure the voltage over the resistors. As the 7654 doesn't provide DC current but PWM current (32 kHz) you will have to acquire the data pretty fast (at least with 200 kHz). This could be done with a DAQ-board like the PCI-6220. Additionally you will have to do some math to calculate the RMS value of the current.
Control voltage measurement:
You could measure the output voltage of the 7344 as it is proportional to the duty cycle of the PWM current signal of the 7654. You will also need some additional measurement hardware but you wouldn't have to use shunt resistors and RMS calculations. The major disadvantage of this option is cabling as there is a single cable connection between the controller and the drive and you would have to use e. g. two external connector blocks and an additional cable in order to be able to connect your measurement hardware to the voltage output of the 7344.
Torque measurement:
Torque is also proportional to motor current so you could add a torque sensor to your motor and measure the output signal with e. g. a PCI-6220. Depending on your hardware setup this might be the best option.
I hope that helps,

Synchronise DAQ and CAN using RTSI

I do a CAN/DAQ measurement using 2 PCI cards and a RTSI cable. However, not all of my analog samples are timestamped
(I'm missing 930 timestamps on a total of 4700 analog samples).
I'm using the Net RTSI config, because with the Obj RTSI config I get nothing but random timestamps for my analog signal, while CAN timestamps are OK.
What can cause this behavior?
Thanks,
David.

First of all: thanks for your reply.
Now, the problem:
I started of one of the examples on the NI site (http://zone.ni.com/devzone/explprog.nsf/6c163603265406328625682a006ed37d/773da68471f9efa4862569e00072a0fc?OpenDocument) and modified this somewhat to log data as binary. I also added a VI to filter out only the CAN ID I'm interested in. (I tried to use an Object instead of a Network Interface, but that resulted in random timestamps for analog... don't know why. Didn't find an example that should work to test with).
DAQ board is used as the master, CAN is set to timestamp the RTSI events.
The result: sometimes less, sometimes more timestamps for analog than I have analog samples.
I have included the sample LV6 program that I use for testing. Main C
AN-DAQ-RTSI is for acquisition, Main Reporting to read the measured files. 2 sample measurements are included too. Second example only contains noise, but ALSO has different number of timestamps than samples for analog.
Gee, I hope I didn't bore you. )
It would be great if someone could give me some advise.
Thanks,
David.

Which external hard drive should I use to save my iTunes library?

Hi,
So I have collected so much music and movies in iTunes that my internal HD is practically full. (Library is over 500GB of 1TB and the rest is taken up with my apps and programs.) It's time to purchase an external hard drive to transfer my library to. Furthermore, I currently have a 2TB WD My Book for Mac that I am currently using for backup. The My Book is also full and Time Machine is deleting the oldest backups to make room for the current ones.
Here is where I need everyones advice. I am planning on purchasing a 3TB WD My Book for Mac. I am planning on purchasing more movies for iTunes. Which external hard drive should I use for what? Option A or B
Option A: Put my iTunes library on the 2TB external hard drive and use the 3TB for backup
Option B: Put my iTunes library on the 3TB external hard drive and continue to use the 2TB for backup
Also please give me your reasoning.
Thanks everyone for your responses!

Limnos,
So, let's go one step further with this. I read your reply to moving iTunes library to an external hard drive: https://discussions.apple.com/thread/4594518?tstart=0 However, if I move the iTunes library, will this include all the movies and apps that I have purchased?
Thanks!!!!

Should I use Time Machine?

I have a new Western Digital My Passport Essential 320GB external hard drive. I also have an old PowerPC iBook G3, with a 40GB hard drive and a dead logic board. I can still access the iBook's HD by hooking it up to my current MacBook and starting it up in Target Disk mode. My current MacBook has a 120GB hard drive, which is getting full.
This is the first time I've ever used external storage. What I would like to do is:
a) copy the contents of the iBook's HD to the external HD;
b) back up the contents of the MacBook's HD;
c) free up some space on the MacBook's HD.
My questions:
1. Do I need to format the external drive before doing anything? If so, am I right in thinking that I should do this in Disk Utility > Erase, and choose 'Mac OS X Extended (Journaled)'?
2. If I do this, do I need to worry about the files that were already on the drive when it arrived from the manufacturer? (I might keep the User Guide pdf, but everything else seems to be .exe files, or files for which there is no default application specified to open them.)
3. Do I need to create a partition on the external HD for the contents of the old iBook HD?
4. Will Time Machine work on a partitioned external HD?
5. Should I use Time Machine to back up the contents of my MacBook, or do it manually? The things that I'm most concerned to back up are my photographs. However, these are also the files which take up the most room on my MacBook HD (I shoot in RAW - lots of 10MB+ files), so are the obvious candidates for files to keep on the external HD in order to free up space on the MacBook. If I back up using TM, then erase some photos from the MacBook hard drive, will TM then erase them from the external hard drive as well - either immediately or when the external hard drive fills up - or will they be safe forever? Sorry, I'm not entirely clear how TM actually works...
I'm a real novice here. Advice on any or all of the above will be much appreciated.

If it's not HFS+, it needs to be formatted to HFS+ (Mac OS Extended - Journaled) via Disk Utility. All data will be lost. See Answer 4.
2. If I do this, do I need to worry about the files that were already on the drive when it arrived from the manufacturer? (I might keep the User Guide pdf, but everything else seems to be .exe files, or files for which there is no default application specified to open them.)
If you want to keep the files, copy it to another location.
3. Do I need to create a partition on the external HD for the contents of the old iBook HD?
If you want to.
4. Will Time Machine work on a partitioned external HD?
Yes, but it needs to be formatted HFS+. If you are creating a separate partition, you use a GUID partition map for an Intel iMac (APM for PPC).

Absolutely NOT! TM is not for archiving. You delete files are NOT safe forever.

Which version of PC suite should I use to copy all...

I have an old Nokia 6610 which is on its last legs. There are about 130 text messages stored on the phone itself, in various subfolders within "My folders", one message in the Archive folder, and about 8 messages in the Inbox (the Inbox messages are stored on the SIM card - Vodafone Pay As You Go). I also have 14 pictures stored in a "Pics" folder in the Gallery. All my Phone book entries are stored on the SIM card. The text message memory is virtually full, and I often have to delete existing messages before new ones will arrive.
My computer is a Power Mac G4 running Mac OS X 10.4.11. For those that are interested, it's this model here:
http://www.everymac.com/systems/apple/powermac_g4/stats/powermac_g4_1.25_dp_mdd.html
On the Mac I have Microsoft Virtual PC 7.0.2 which runs a copy of Windows 2000 (5.0.0.2195 Service Pack 4) under emulation.
I have a fake/third party DKU-2 cable which came with a CD which contains the installer "Nokia_Conn_Cable_Driver_150_2_eng.exe" and the installer for PC suite 6.6.
Many months ago I ran the "Nokia_Conn_Cable_Driver_150_2_eng.exe" installer (within the Windows 2000 Virtual Machine) and also installed the latest Windows 2000 compatible version of PC Suite that I could find at the time - 6.86 (the installer file is called Nokia_PC_Suite_rel_6_86_9_3_eng_web.exe).
The software installed successfully, and it seemed to detect the phone via the DKU-2 cable, but I wasn't able to access any of the information on the phone. This isn't really surprising, given that the phone wasn't really directly connected to Windows - it was going via a Mac USB 1.1 port, masquerading as a port on the "PC".
What I am wondering is what software do I need to use so that I can copy all the text messages from the phone (& the 14 pictures too if possible) to my computer, preferably with the sender names & folder structure intact, so that when I buy a new Nokia phone, I can copy them all to it? I've not decided on which new Nokia to buy yet. It might be the N95 8GB, the N96, or perhaps just a basic model. It will be a current model though, not a second hand one.
My first choice would be to use software that was Mac native, but I'm not sure if there is any that would do the job. My second choice would be for software that could run on the Windows 2000 Virtual Machine. If neither of these options are possible, I could borrow my Dad's 6 month old PC laptop, which runs Windows Vista Home Premium, and use that.
If anyone has any experience/thoughts on this, I'd greatly appreciate their (detailed!) input & advice. Although I've very experienced IT-wise, I have zero experience of mobile phone software.
Many thanks.

Go to Solution.

Just to follow up from my previous post - I did indeed decide to keep the 6220 classic as my new phone.
Yesterday I installed the Nokia_Conn_Cable_Driver_150_2_eng.exe driver from the CD
that came with my third party/fake DKU-2 cable onto my Dad's Windows Vista Home Premium laptop. Knowing through 15 years bitter experience working with PCs that once a newer version of a piece of software has been installed on a PC, it can often be impossible to subsequently install an older version, even once the newer one has been successfully "removed", I decided to install the 4 versions of PC Suite at my disposal in version order, with the oldest first, and if a version didn't work, to uninstall it, and then install the next oldest one, and so on.
I started with the version that's on the CD that came with my 6610 - version 5 point something. The installation went fine, and after re-starting, I followed the instructions to connect the phone to the computer with the cable. Unfortunately a Vista error message appeared saying there was a problem with the "unrecognised" USB device. PC Suite meanwhile just got stuck in a loop trying to connect to the phone. (The phone was switched on & unlocked!). After trying unplugging & replugging the phone etc, I uninstalled PC Suite, and then tried the same thing with the next oldest version of PC Suite that I have. This is version 6.6. The exact same problem occurred. I then uninstalled that and tried a version I had downloaded many months ago - version 6.86.9.3. The same thing happened, except this time after a while PC Suite gave up trying to connect and displayed a box offering links to places like this website that might help me solve the problem. I then uninstalled that, and then installed the current version of PC Suite - 7.0.8.2. The same thing happened as with 6.86.9.3.
There are, to my mind, 2 possible explanations for all this. Either the data socket on the phone is damaged in some way, which is possible, given that the phone got wet back in February and had to be repaired, and the first repair shop i took it to managed to dislodge the charging socket (which is right next to the data socket) during their botched attempts to fix the phone (another shop fixed this), OR, as I hope is the case, the cable is the wrong one, despite it fitting perfectly.
I've noticed that in several places (the phone's manual, readme files that come with the various versions of PC Suite, etc) that the DKU-5 cable is mentioned far more often than the DKU-2, which suggests that maybe I need a DKU-5. Also, if you go to the PC Suite download page and select the 6610, the cable that's mentioned is the CA-42. Another alternative is that the DKU-2 I have just doesn't work, given that it's not a proper Nokia cable.
Does anyone have any idea which cable I actually need to use to get the PC to talk to the 6610?
Also, in case you were wondering, the reason I tried 4 different versions of PC Suite rather than just the current version is that I've read on these forums that certain newer versions of PC Suite don't have certain features that certain older versions do, depending on the phone in question. This has caused much frustration for people, judging by the comments I've read. Given that what I want to do is to copy all the text messages from the phone (& the 14 pictures too if possible) to my computer, preferably with the sender names & folder structure intact, it may be a case that an older version of PC Suite will allow me to do that, but a newer version might not. This is especially true given how old the 6610 is. Of course it may be the case that an old version of PC Suite that allows me to copy the texts & pictures to the PC won't work with my new 6220 classic. If that's the case, I hope that I can install the current version of PC Suite over the top of the old version, and then copy everything onto the new phone.
If anyone has any firm ideas about what cable (& version of PC Suite) I should be using, I'd be most grateful.
Thanks for your attention.
