Vi for Keithley 2182
Hi!
Did someone wrote a Vi for Keithley 2182 nano-voltmeter that read/write to
the buffer of that device and is willing to share it?
Thanks

There is a LabVIEW instrument driver for the Keithley 2182 on the Keithley web site at:
http://www.keithley.com/PRODUCTS/modelNumber_tmpl.jsp?page=softwareDownloads&modelNumbers=2182
It is for LabVIEW 5.x, so it will load up in any version from 5.0 on.

Keithley 236 SMU and Keithley 2182
Hi
I am new in labview and I would like to measure voltage from Keithley 2182 triggered from Keithley 236 SMU in delta mode.
I did not see any command for delta mode in Keithley 236 SMU. So I don`t know how to send two opposite current and read in the Nanovoltmeter.
Is there any simple vi. for this operation
Thanks
Ser.Hello 454,
Have you downloaded the LabVIEW drivers from Keithley's website?
http://www.keithley.com/support
I took a look at what's available and there are triggering examples in the .llb files.

Recording Temperature and Voltage measurements using Keithley 2182 Nanovoltmeter
Hello all,
I am relatively new to LabView and looking to extend a vi I am currently using.
I am trying to record voltage and temperature measurements from a Keithley 2182 nano voltmeter using a GPIB cable. I have a vi that can do this for either voltage or temperature not both. At the moment I only record what is shown on the display of the nano voltmeter.
Could somebody explain how I could get labview either to change between voltage and temperature on the nano voltmeter or whether it is possible to have two simultaneous measurements of temperature and voltage and how I would achieve this.
Thanks
MikeHi,
For each read, no matter Temperature or Voltage there is a certain command that is send to the voltmeter.
I don't think (actually I'm pretty sure) you cannot read it in parallel but you can do it successively: One read Voltage, one read Temperature and so on.
There should be something like:
while not STOP do
1. send GPIB command for changing Keithley to Voltage Measurement
2. send GPIB command for Voltage Read
3. read GPIB -> Voltage
4. send GPIB command for changing Keithley to Temperature Measurement
5. send GPIB command for Temperature Read
6. read GPIB -> Temperature
end
You can take a look in VI to see which are the commands send for Voltage and Temperature reads and to mixed them like I described it above.
If you don't manage it share your VIs (for temp and volt.) maybe it will be easier for me (or something else) to give you some additional advices.

6485-READ.vi 79 KBI'm currently (excuse the pun) also using the Keithley 6485. I found the easiest way to to initialize it and read data was to use the examples available on the Keithley website. You do however also have to download their 'Keithley Input Output Layer' code to make them work. I downloaded version C02, assuming it was the latest version available.
http://www.keithley.co.uk/data?asset=52766
I tried running your VI on my computer and it didnt work also.
Heres the stripped down VI that works for me (if it successfully attaches! My first reply on here).
It's for LV9, so hope it works on LV8.5 also.

Labview drivers for keithley DAS 1600
hai all,
I am searching quite for a long time for the Labview drivers for my Keithly Metrabyte DAS 1600 data aquisition card. Could any body provide me some weblink or some source from where I can download the drivers.
thanks in advance.

nandaDear Nanda
Thank you for choosing National Instruments!
National Instruments provides drivers for NI products only. If you need drivers for other third party hardware, you will need to contact the hardware manufacturer for the drivers and VIs to interface with LabVIEW. You can go to the download center for Keithley from this link and typing in DAS 1600 in the search page. This will bring up a section with downloads - wherein you can find driver updates. If you do not find information here, then you may need to call in tech support for Keithley to get the drivers.
Hope this helps.
Thanks and Regards

I need GPIB Driver for Keithley 263 Calibrator/Source Meter using Labview. Can anybody help?
Thank you in advance.Hi,
on Keithley's website is explained :
"The Model 263 offers a more economical, more precise alternative to the Model 6430 or the Model 236 when used as a low-current source. It is used almost exclusively as a current calibrator."
This leads to Model 236.... A LabVIEW-driver is available @: http://search.ni.com/query.html?lk=1&col=alldocs&nh=500&rf=3&ql=&pw=595&qp=%2BContentType%3AInstrumentDriver+%2BIDNetManufacturer%3A%22Keithley%22&qt=&layout=IDNet
Maybe you have to "reconstruct" some parts - but it will help.

GPIB Instrument driver for Keithley 2015 multimeter.
Hi,
Does anyone have instrument driver for Keithley 2015 multimeter or does
anyone know where can I find it? I didn't find it from NI web pages.
Thanks,
-HarriDid you check Keithley's site Harri? I think I got one from there. They were anxious to know, Keithley that is, which drivers would be worth creating for CVI. Maybe you already have this worked out but otherwise talk to your friendly neighborhood Keithley rep. Hope it helps.

Labview VI's for keithley 617 meter
Respected Sir,
Now I m trying to interface keithley 617 electrometer using Labview and GPIB card. For that we have created code. Using this we want to measure continuous readings form 617.
We are getting reading from 617 meter. But we want to measure current for that we have connected 1 kilo ohm resistor to the device using BNC cable(According to Keithley manual) voltage range is -1 to 1 increment of the order of .1 means after -1 automatically labview must take -.9 next -.8 next -.7 till up to 1 after that it must stop collecting data.
I m going to attach my code. Please try to solve according to our need.
With regards
Shridhar

Good afternoon and I hope your well today.
Are you using the VIs which I found here, at ni.com/ident

The VI titled Keithley 617 array.VI setups/reads/close the take for 100 measurements - for one setting.
Now I have seen for other instrument drivers they have coded a sweep - which is what you're after.
The process to achieve this is loop through this code, but changing the voltage range and hence reading back different data. Have you got code that updates the voltage range?
I am sorry but I can't code in LabVIEW 5,
Hope this helps,
Kind Regards

Using IVI driver for Keithley 6485
I am trying to learn how to use IVI drivers. I installed IVI drivers for two instruments, an HP34401A and a Keithley 6485. I was able to get the HP to work in simulation mode (I don't have the hardware). I am also trying to get the 6485 working in simulation mode. The attached vi was provided by Keithley. I configured a logical name in MAX, but this name doesn't show up as an option when I edit the "logical name" control on the front panel. I changed the Initialize vi to Initialize with Options and added a command string control to set the mode to simulation, manually entered the correct name in the control, and ran the program. No error was indicated in the Initialize vi. After the configuration vi runs, however, the following error was flagged:
Error -1074135023 occurred at IviDmm IVI Error Converter.vi
Possible reason(s):
Primary Error: (Hex 0xBFFA0011) Function or method not supported.
Elaboration: FunctionId: 46, FunctionName: ConfigureMeasurement
Complete call chain:
IviDmm IVI Error Converter.vi
IviDmm Configure Measurement.vi
KE6485_ZeroChk_LV86.vi
This error is being generated by IviDmm Configure Measurement.vi, which is apparently installed NI code. Specifically, the error appears to be thrown when Call Library Function Node is invoked and IviDmm.dll is called. I wasn't able to track down any further info as to the meaning of these error codes.
Thanks for your assistance.

KE6485_ZeroChk_LV86.vi 14 KBHello,
3rd party devices will show in MAX only when that device is listed at a specific place within your computer's registry. Non-NI hardware may not show up in MAX.
As far as the logical name is concened, unfortunately, you will have to contact Keithley to get a better understanding of their code.
You could download our IVI driver from the link below as you might have better luck with it. You can find any of our 3rd party drivers at www.ni.com/idnet.

Voltage sweep and measure current for Keithley 2400
Dear All
Hello,
anybody can help me?
In spite of nearlly10 days i am searchig to find any labview 2010 program for voltage sweep and measure current that works with RS-232, i has not able finde anything exept some exapmle that read single and multiple data. I has tried to learm labview and changed some prorgram from gpib to RS-232 but i couldn't.
In another attempt i find a good "votltage sweep and measure current" VI that work with RS-232 in labview 5.1.1. i converted it to 2008 but it need to old driver (ke24xx.dll) and dont work in my labview 2010 and I could't find old driver.
in these 10 days, my project on thesis has been stopped and i couldn't do anything for our keithley.
Please helpe...
in following i attached these files:
1-first it is voltage sweep that works with GPIB
2-Vi that i change gpib port to visa (rs232) that i don't know why it dosen't work.
3-it is Vi related to "votltage sweep and measure current" that works with RS-232 but need to old dirver so i can not use it.
4-SubVi needed to run program of 3 (but there is no driver for these subVIs) has been atached in reply post of this post
if any body has this program ("votltage sweep and measure current" that work rs-232) please send for me
thanks in advances.

I V new2.vi 103 KBThe first time you asked this exact same question, you were given the way to get the driver and told that one of the examples does exactly what you want to do. You have chosen to disreregard this and pursue other options for these close to 10 days. If your thesis is stalled, that is really your own fault for not listening to the answers you were given. I have no idea why you would do this but I would suggest you go back to the original thread, reread it. and if you want further help, explain what the problem with the NI driver is.

Automate measuremen​t for Keithley 2520
Hello,
I am new to LabView for instrument automation. I am trying to write a LabView program that will measure the L-I-V characteristics of a laser diode from the Keithley model 2520. There are no instrument drivers for this tool, so I turned to Keithley and found the attached example program. It does not work when I attempt to make measurements. Will I have to write a program from scratch, or am I likely using the example program incorrectly?
Thanks,
Nick

Labview drivers for Keithley 181 nanovoltmeter and Lakeshore DR-91C temp controller
Hi,
I am looking for labview GPIB drivers for the following instruments.
1. Keithley 181 nanovoltmeter
2. Lakeshore DR-91C temperature controller
I will greatly appreciate information about the above.
Sincerely,
A.V. MahajanHello,
I just searched the web for both of these and was unable to find anything...I found a CVI driver for the Keithley 181 on the NI website, but I doubt it would be a simple conversion with the "Convert CVI Instrument Driver" utility in LabVIEW...it certainly wouldn't hurt to try, however. Anyway, I guess about the only option you have at this point is to contact the manufacturers of those devices and see if they have any un-published drivers...perhaps they're not supported, but it's better than nothing.
Good luck in your search. Have a good day.

Keithley 2182A readout with GPIB
I have trouble reading out the buffer in the keithley 2182A nanovlotmeter after a measurement sweep. I am using the Keithley 2182 buffer read.vi developed by Keithley, and am running on Labview 2010.
When i run the buffer read.vi it returns an array with the correct stored measurement values. When i run the vi as a subvi in my larger programme however (as I need to do), it returns an array with the correct number of elements, but with the first stored value in all of the elements of the array.
I believe the vi was originally made for LabView 8.5.
Has anybody encountered a similar problem with reading out buffers? Is it a timing issue that when run as a subvi it only reads the first element?Chris.smiet wrote:
I use the 2182A nanovoltmeter in conjunction with a 6221 current source, connected with a trigger link cable. (I know i can also address the 2182A via the 6221's vi's and a rs232 cable, but i want to address it directly via GPIB for added flexibility). I perform a current sweep (with 1024 steps) with the 6221 and want to measure the resulant voltage and store it in the buffer of the 2182A.
The problem is that I cannot read out the buffer of the 2182A using the given vi as a subvi (as it is supposed to be used). I tried a much simpler vi to store 10 random measurements (no wires attached, what is measured is random) in the buffer (trigger = timer). When I read out the buffer, the vi returns an array with all elements the same, and equal to the first element in the buffer (wich I can read out from the keithley by using the front panel)
I use the "Keithley 2182 buffer read.vi" in the keithley 2182 version 6 driver library downloaded from http://www.keithley.com/base_download?dassetid=10070
A trigger link cable? Doesn't that kinda raise a flag?
Do you know what commands are in these VIs you are using? Do you understand what is happening with the triggering of measurements?
Understanding *how* the instruments works is important. And it starts with *reading* the manual. -
Keithley 2400 VISA driver limited resolution
Hi,
I have a Keithley 2400 sourcemeter, what I use in the +-1mA range, as a current-source. This is the driving part of a PID control.
I use the official VISA drivers, and everything is okey, except that, it seems I cannot use the specified resolution from LabView.
In this low +-1 milliAmp range, the usable resolution is 50 nanoAmperes. In manual mode, everything is ok, I can set for example an output current to be:
-0.245450 mAmperes.
But when I use LabView with the Configure Output .vi from the official llvlib package (i attached it) it rounds for microAmps:
For example the above double value will become: -0.245 mAmperes.
This is really bad for my project, since I need the 50 nanoAmp resolution for the really fine control.
Can someone help me?
Thanks in advance!

Configure Output.vi 18 KBThanks very much!
Now I learnt that, I should be always suspicious even with "official" libraries and drivers.
Actually there are two LabView drivers for Keithley 2400, one from Keithley, it is an exe installer type, and the other from National Instruments. I became curious about this bug, and I checked the Keithley VISA drivers, they are okey, they use everywhere double precision variables.
But if you have a look at the NI Keithley 24XX.lvlib:VI Tree.vi, where is the full list for available VIs, there are many problems I think. At many places (voltage sensing, sourcing, etc) the programmer just used single precision variables to pass information.
I think these problems should be reported toward NI, but I do not know what is the way to do this... -
Keithley 2701 LV driver: Setting the scan rate?
I downloaded the Keithley 2701 LV driver and the example programs work great. There is just one question that I have. I cannot find anywhere in the examples or in the LV drivers how to change the scan rate or scan interval. Everything else I'm able to change, such as number of points, channels, voltage levels, etc., but I can't figure out how to change my scan rate to once every 0.5 seconds or 1 second.
I'm not sure, maybe this is a question for Keithley but since it is a LV driver I decided to post here first.
I'm using LV8.2
JeffI am using the Keithley 2700 with the 7700 cards. There is a vi named "ke27xx Configure Aperture Timing.vi" in the "ke27xx.llb" .
The vi sets the integration time for the A/D converter. I was measuring 500uv and needed to improve my accuracy so increased my integration time.
