Remove custom scaling DAQmx

What I am working on is a calibration VI so that a user may come up with scales for different channels in their DAQ tasks which they create in MAX. When I start my VI, I create a copy of the existing task from MAX because that task includes the channels to calibrate. But, in creating this copy, my virtual task includes the scaling. I want to remove this so I get raw voltages. How can I do this?
Essentially I want to programmatically set <No Scale> the same way you can in MAX.
My not-so-valid attempt. I was hoping "no scale" was a custom scale.

I actually have tried that and it seemed like it didn't work. But I will try again. I tried just to make a scale that went by increments of 1. I was somewhat rushed so I may have had something set up wrong, but from what I remember the data was still being scaled.

DAQmx Custom Scaling Issue

I have created custom scaling for DAQmx. I have the following issue similar to this http://forums.ni.com/t5/Multifunction-DAQ/daqmx-custom-scaling-setup-issues/td-p/805374.
I am scaling a 0 to 5V signal to 0-100 sccm.
the slope is 20 with a Y-intercept of zero.
Everything scales fine up to 1.07V then it displays 21.56 sccm for any measurment above this voltage.
Cant figure out what i am doing wrong. I have verified the DAQ card is measuring volts correctly above 1.07 in NImax.

Thats not how i read this:
maximum value specifies in units the maximum value you expect to measure.
minimum value specifies in units the minimum value you expect to measure.
Max values measured is -10 to +10V , If you are correct shouldnt it say "max scaled value" ?
It is the maximum value of the number that will come out of the DAQmx driver. Since DAQmx applies that scale for you, it is post scale value. So you really need to put in 100 sscm for your maximum.

Acquire 2 digital signal with custom scaling (Engg Units)

I am a newbie to DIO world.
I have write a VI to acquire 2 digital signals. one from a load cell and other for motor rpm (pulses). I need to acquire these two signals and then convert them into engg units using custom scaling and write them to a txt file with time stamp.
Please suggest best ways to accomplish this task.
Thanks
DAQG
Solved!
Go to Solution.

Look at the examples on DAQmx in the example finder.
You wouldn't actually be acquiring 2 digital signals. You would be acquiring an analog signal from the load cell. A digital or counter acquisition is what you would acquire from the motor. Search for analog measurements and counter measurements in the example finder. Some of the example should show you how to apply the custom scaling.

Custom Scaling greyed-out, still no answer on boards.

I'm still looking for an answer on how I can access my custom scaling options.
Changing the resolution does not affect it. I have a 1600x900 moniter, and I would like to change the aspect ratio. Can someone please tell me how to access these options?
What is custom scaling:
(These options are not actually availiable)
Custom Scaling Selects how displayed information on the monitor will be formatted. Select:
Fill to Screen - Image fills the entire screen and might look distorted or elongated because of non-proportional scaling of height and width.
Fill to Aspect Ratio - Image is sized to fit the screen and maintains proportional image.

What is the markup that you have used for the gallery pages? It looks like gibberage to me which is a far cry from HTML.
Gramps,
Gibberish because it's a link to an SWF file, not HTML.

Remove custom field instead of default text field

I need migrate to SharePint 2013 from 2007.
In SharePoint 2007 List include a custom field.
Dont use the custom field again,
I want remove custom field instead of default text field (remain metadata).
How to do it ?
Thanks

Hi ,
According to your description, my understanding is that you want to migrate SharePoint from 2007 to 2013 with managed metadata column. Is it right?
If you need to migrate managed metadata columns, you also need to migrate the Managed Metadata Service application. however, when you use this method, only global terms are available but the local terms are not available.
So, if you used the local terms for the managed metadata column, I suggest you use a third party tool or manually re-create the column in the destination list.
There are some articles about migrating managed columns, please take a look at:

Custom scaling of data without MAX?

Okay here's my problem. Hopefully you can help me or offer some helpful advice.
I am creating a user interface for data acquisition (only analog inputs are used). Thermocouples (Type J and Type K) will be used, as well as factory calibrated strain gauges. Some other sensors that can be linearized on a 0-5Volt scale might be used too.
I originally had my program set up where the user had to set up their channels in MAX and then come to the program I made. There will probably be a lot of scale/offset changes made by the users so channel configuration needs to be flexible. I changed the program to custom scaling. Instead of virtual channels the user just enters scale and offset values. These values are saved to a text configuratio
n file and later used on raw voltage.
Then I realized I would have to have the user input what type of sensor they are using because I'd have to compensate for CJC in thermocouples. AND, I dont think the SCC-TC02 is linear.
*Am I right in thinking I will have to use case structures when I finally scale data for LINEAR versus J THERMOCOUPLE versus K THERMOCOUPLE?
*How innacurate would my readings be to use the Labview's Thermocouple scaler VI and set the CJC to 1.25 volts (25 degC) rather than reading from Channel X+8.
*Is there an easier way to do what I'm trying to do? I know people do custom scaling, how is it done?
THANKS.

LabVIEW 6.1

I'm not sure I see where your difficulty is.
I have always used custom scaling, MAX never did quite enough.
I have a cluster for each channel. The cluster contains a scaler (EU/Volt), an offset (EU@0V) and a channel type enum, among other stuff (channel name, units, filters, etc.)
When processing the data, look at the cluster for that channel. Use a CASE statement on the CHANNEL TYPE value. If linear, multiply the volts by the scaler and add the offset - you get EU (Engineering Units) out. If the channel type specifies some other type, use the appropriate linearization routine.
How innacurate would my readings be to use the Labview's Thermocouple scaler VI and set the CJC to 1.25 volts (25 degC) rather than reading from Channel X+8.
<
p>
Depends on which type TC, and where you are on it's range. You might expect 20 degrees or more error at the high end of some ranges, without proper CJC.
There's no easy answer to that question.

Removing custom camera profiles

I am running windows 7. How do I remove custom camera profiles created by x-rite passport?
thanks,
Randy

Randy,
Be careful deleting profiles, particularly from the OS. I think the x-rite manager actually hides profiles instead of deleting them which is probably just fine.
Regarding actual deletion, I am not certain so please test this - if the profiles are not being used by any images, deleting should not be a problem. If some images are using them however and the profiles are deleted, the next time that image renders it won't be able to find the profile and will have to render using an Adobe default color profile. To compound this problem, there is no easy way to filter by color profile (a couple of plug-ins exist I think) so it becomes difficult to know if it a particular profile is being used.
One way around this, again I believe this is correct but please test for yourself, is that if you use the DNG format for your RAW images, when you update the DNG Preview (instead of Ctrl-S) you embed the color profile into the image and therefor you can delete them. This can be handy when you have one-time uses for the special color profiles.

Custom scaling of DAQmx channels

Hello,
I am attempting to set up a triggered acquisition using DAQmx custom scales with 1 virtual channel containing 3 physical channels. What I am trying to acheive is to have independent scaling applied to each physical channel input.
I have attached a snippet of my code - when I examined it in operation, only the last channel in the array is applied to the task with the final array scaling values.
Could anyone give me some advice on how to improve this?
Regards
Dave

I am not sure what is happening in your customscaling.vi as you havent posted it.
I would create the custom scales first and apply it while the task is being created as below. You will need to adjust the values as necessary.

How to remove custom authentication provider in weblogic server 11g

Hi ,
I am trying to remove the custom authentication provider in weblogic server 11g, It disappears when i delete it from list of authentication providers. But upon server restart it appears again.
Documentation for 10g says delete it from service administration but i couldn't find one in 11g. Please help me in removing the custom authentication provider
Thanks
Sandeep

You can try editing the config.xml file and removing it there. (Re: After provider reorder I cannot login admin server console
If you are referring to a jar file - custom authenticators are usually placed in the <middleware-home>wlserver_10.3/server/lib/mbeantypes/ directory.

How do I add and remove custom mail sounds

I have a custom mail sound that I would like to remove from Apple mail. I have another sound that I would like to add to mail.
There was a web site that explained how to do this for 10.4 but I cannot find a procedure for doing it with 10.5.

I'm wondering if Apple changed how these sounds are done from 10.4 to 10.5
I actually replaced one custom sound with the very same custom sound, this seems to have solved my problem.
Thank you for taking the time to help me.

How to remove channel from DAQmx create Task.vi

Vikas H. Kumthekar
ASE
Tata Consultancy Services
Pune-1

How are you using the DAQmx Create Task.vi? Are you using it to include a global channel or copy a task that was previously created in Measurement and Automation Explorer (MAX)? If this is the case the only way to remove a channel would be to delete the global channel or modify the physical channels for that task in MAX. If you are creating a new task you can use the DAQmx Create Channel.vi to specify the physical channels that you would like to include or exclude.

Remove custom captions from cache, CS5

I created a number of custom captions in CS5. The captions work fine but are no longer needed. I removed their .bmp and .fcm files from the Gallery\Captions folder but the captions still appear in the Caption Type drop-down list. I can't seem to get rid of these unwanted captions. They seemed to be cached in a mysterious location and refuse to go away. I have cleared project cached files, uninstalled/re-installed Captivate 5, exited/entered new projects, rebooted the PC, and scanned the PC registry. How do I remove these captions?
Other recent postings have raised this same issue but I couldn't find any answers.

Hello,
I think your are pointing at Captivate 5 (Captivate is not part of a Creative suite, so the 'CS5' doesn't apply to it)?
Did you try to delete the Preferences folder in CP5? This has to be done while CP is not running. It depends on your OS. I'm on Windows 7 and the folder 'Captivate 5' can be found there in this path:
C:\Users\YourProfile\AppData\Local\Adobe if Windows is installed on C: Replace 'YourProfile' by your username
You can delete the folder, but will lose all your preferences. When restarting CP a new folder will be created. This replaces the "*.dat" file from previous versions.
