How to Read Current Source of Keilthly 2400 in Labview

I use an IEEE-488 GPIB connection to a keithley 2400

I use an IEEE-488 GPIB connexion to a keithley 2400. I go an error - 111 an error header seperator and a header non defined-113. I demand to know how to set up this problem and install this keithley with a probe workstation. I'm new to labview and uses old code that I attached below all information on troubleshooting, the block diagram would be greatly appreciated thanks.

Why are you using the sometime code? Go to help > discover instrument Drivers. Follow the directions.

Y'all take Keithley 2400 IVI driver KE2400_32.dll c# wrapper?

I have download Keithley 2400 IVI driver to http://www.keithley.com.cn/support/data?nugget=16504

Simply it merely supports vb6. The commuter dll is C:\Programme Files\IVI Foundation\IVI\Bin\KE2400_32.dll

I search the Forum, Assistant .Net Studio Instrument pilot measure could generate the c# of the IVI driver wrapper.

Unfortunately, I do not have measurement studio.

And so, could someone give me a help to generate a c# for KE2400_32.dll wrapper?

Kind regards.

Here you go - see fastened, I don't have a chance to test yous.

sweep the voltage keithley 2400

Hi friends,

I ve made a small program (reusing an I found in the web) to generate a curve using Keithley 2400. I want to sweep the voltage of 1V-1 using for example 10 points and get the current in a graph and a table.

Still, something is not because I have only (not yet correct) measure and no epitome in the chart and no information in the table.

Could someone advise me hither, please?

Any help is welcome!

Thank you

Hi LabVIEWers,

I ve you have a problem receiving data from Keithley 2400.

I g using a distributed (attached) Keithley LabVIEW instance and suddenly it does not work. When I run the program it sends the information to the Keithley and a browse is performed. The problem is when the scan is done, no data back to the plan so I can't save all data or see any result in a chart or table.

I ve tried to debbug program using the option to highlight and information technology is for me that the data are intended to the curve, just I have nix (merely #0 in the output of the Sub - Half-dozen last earlier the graph).

The strange matter is that this plan works and so far, no idea what can be the problem?

Thank you very much!!

VISA read timeout fault - Keithley 2400

I am using LabView 2010 to command a Keithley 2400 Sourcemeter on an RS-232 Interface. I want to prepare a measure and take a reading (e.chiliad. ground voltage / time)

I took an example of "Keithley ReadOnly" library lawmaking, but the 1073807346 error to recollect box "initialize". Then I looked in 'Initialize. VI"and institute there is a VISA (timeout error?) reading error. I have attached two screenshots that shows errors. Can someone tell me how to solve the trouble? Moreover, I am very new to labview, if someone could suggest a solution that is not likewise 'Advanced '? Give thanks you lot very much.

Keithley 2400 bug

Howdy

I'yard trying to run a Keithley 2400 SourceMeter with LabView using the most recent driver (Keithley 24XX) and the example VI "Keithley 24XX Read Single.vi".

After selecting the GPIB accost, I run the plan and Labview throws the following error message:

Mistake 1074000000 has occurred to Keithley 24XX.lvlib:Error Query.vi

Possible reasons:

Reports of the instrument:
-113, "undefined header."
-230, "information corrupted or tainted."
-420, "request non COMPLETED".
0, "no error".

I also have a 2000 Keithley multimeter upward and the runing with his latest commuter and plan instance and it works fine.

What could be the problem?

Thanks in advance!

Me once again:

I've updated the Firmware to Bishop C32 and now it works!

Keithley 2400 and 2000 to Windows 7 computer connectedness

I have a Keithley 2400 sourcemeter and a 200 Keithley DMM connected to my computer via IEEE-488/GPIB KUSB of Keithley. When I plug the USB in my computer it does not recognize the connection, and in fact my programme OR measurement and Automation does not recognize that they are connected at all. Using the help function in LABVIEW I also installed the drivers appropriate for the 2400 and 2000, but without effect. Someone has communication on how I could get these to connect to my computer? I intend to apply for a test of Van der Pauw.

Tried to contact Keithley?

It is their equipment and I know from past experience, that they are familiar with the software NOR.

You volition get results much more rapidly.

Many people here use software and hardware. I have no personal experience with the KUSB.

How to ready the time departure between each data when using keithley 2400 scanning

Hello friends,

I use scanning Keithley half-dozen the extent of SCANNING and acquire vi. I want to measure the voltage for each step and a pause betwixt each ii data, so I need a delay between each I step.

I'm a starter to utilize Labview, give thanks you very much for your answers.

Perry

As Dennis says, if you utilize the built-in browse part, you will need to consult the transmission. See Department 10-sixteen (this is page 10 of article xvi, simply paragraphs not only 10, 16) for the manual Keithley 2400.

The Keithley 24xx series has a speed of measurement in units called PLC (Power line Cycles). The default speed is 1PLC, which means a measure is taken with each cycle of line 1 power supply or ane/60th of a 2d (xvi.67ms). 24XX can range from 0.01 PLC (all 0.16ms) 10 PLC (all 166.6ms). The faster y'all measure, the less accuracy you become.

To programmatically prepare this value, the command is

ENSe:Current:NPLCycles

ENSe:VOLTage:NPLCycles

Depending on what you are sensing and where is the number of controllers from 0.01 to 10.

Another factor that will determine the time between information points is the bike SDM. These are more complicated, look at your Keithley transmission for more information. Look at article 6 and article 11 for more information.

Note:

PLC times are based on a cycle of threescore Hz US.

latest version of the driver for keithley 2400 sourcemeter instument

Hello all

I'm unable to connect with sourcemeter Keithley 2400 with GPIB / Rs232. (currently using the driver from keithley Web site)

I did a search preliminary Forum and learned that there is some bugs in drivers.

Then comes the concluding avilable pilot site OR the corrected version?

http://sine.NI.com/apps/UTF8/niid_web_display.download_page?p_id_guid=25B255F3AA83660EE0440003BA7CCD...

The one above IS suitable for the ii abd GPIB, RS232.

concerning

Lorris Somasundaram

I think there has been a problem in the GPIB bus accost. I used MAX and tried triubleshooting and reattach the GPIB and finally the connected got intrument, pitiful for the inconvenience.

The driver loaded since NEITHER website works very well.

Thank y'all and distressing for the inconvenience

Write error in scan-1073807339 voltage Keithley 2400 to VISA, GPIB

I'm working on a 6 that sweeps the voltage across multiple PV devices, all in two States (light and dark). I apply the SCPI and a GPIB commands to send scan to the Keithely and store it in a retention slot. And then I ask this field using a sub - Half-dozen for each device in the 2 States.  The first Country (low-cal) withal works fine.  VISA writing successfully sends the script to the Keithly and VISA read records of information successfully. But when the VI tries to run the same Subvi in the second State (nighttime), I get the fault of delay of 1073807339 waiting.

Means, I tried to solve this trouble:

-adjustment of the byte for VISA read charge per unit (at i point given, I was getting the error on VISA read, not write)

-accommodate the setting of fourth dimension-out of VISA by the suggestion of Spider web site of nor

-loading of the script on the keithley each time for each scan

In addition,

I collect 100 points of information with each browse-05V to 2V.

Whenever I become this error in order to become anything to connect once more, I have to close out of labview and could power off, power and reconnect the keithly

Help, please. This could exist a problem with my GPIB device? or my Keithley 2400?

Give thanks y'all

I tried all the solutions, simply none of them helped. However, I accept finally solved the problem on my ain. The issue was that the VISA session was not properly airtight / emptied later each scan.  To resolve this event, I added VISA shut at the end of each scan and articulate VISA earlier each scan.

Keithley 2400 smooth change of output range

Hello

I use a Keithley 2400 current source to bulldoze a Peltier module to control the temperature (object multilayer temperature shielded inside a vacuum bedroom) with PID. The process value (PV) is measured with a Keithley connected to a balanced special bridge thermistor nanovoltmeter. With this configuration, I can hit gap type of two-3 nanoV of the thermistor bridge get out, which is about the level accessible with this nanovoltmeter (equivalent to ~ 30 nanokelvins stability of temperature, sensor has a sensitivity 0.ane 5/g). If this configuration works as it should, with a correctly tuned PID command.

However, after the sample (degassing vacuum) the charge of process change is different, and then the Keithley is started automatically in the range of 1 a output. The LabVIEW application automatically checks the application of the PID output using a buffer and min/max for the calculation of the output values. When, for example afterwards a few hours, demand for PID output drops below x mA, the VI automatically irresolute the menses of the Keithley to x range my (using the * command RCL remembered probably setting). So we accept a upper phase resolution in order to achieve the extreme temperature stability. The only problem is that the current existent offsets (lets call it mistake output, or a working of error) are obviously different 1A and 1 my range. And then this automated transition is not "shine" enough, I see that the PID regulation loses its 'hold' on the control and the value of process allows a small-scale swing. Of course, this oscillation is reduced after a while, and the PID can accomplish ultimate stability later on a few hours more.

I would avoid this "lump" in my volition, what would you advice to do? How could I make this transition from the embankment to be smoother?

Cheers for any advice,

Best regards

its that darn * RCL

The Kiethley has the beach there is no reason to recall a series of parameters to change i command parameter.

That being said. The resolution will also change and there will be a crash-land - it'due south inevitable.

Airplane pilot of express VISA Keithley 2400 resolution

Hullo

I have a sourcemeter Keithley 2400, what I utilise in the range of +-1mA, as a current source. This is the driving part of PID control.

I use the official drivers of VISA, and everything is OK, except that information technology seems that I can't use the specified resolution of LabView.

In this range of low +-1 milliamp, the usable resolution is l Nanoamps. In manual mode, everything is ok, I can put for example a electric current output to exist:

-0.245450 mAmperes.

But when I employ LabView with the .vi set upwardly the output of the bundle official llvlib (I accept attached it) he rounds for microamperes:

For instance, the double value higher up would become:-0.245 mAmperes.

It's really bad for my project, considering I need the resolution 50 nanoAmp for really fine control.

Can someone assistance me?

Thank you in advance!

Change the format string to"%.9f; ': ' and run into if information technology works.  Information technology seems that the default precision is half dozen.  Why the original programmer used %due south I have no idea.

conection trouble betwixt labtracer2.0 and Keithley 2400 meter Source

Hello

I take a problem of the connection betwixt labtracer2.0 (published by Keithley,) compiled on Labview and Keithley 2400 meter Source.

My basic connectedness is Source Meter2400, card GPIB (from Keithley) and Labtracer2.0.

Although I have installed the run time Visa 4.four, and labtracer2.0, I can't utilise labtracer command 2400 and get the data from information technology. The warning information point that the labtracer cannot find the run-time information, or there is a script fault if I run the test several times.

In fact, this arrangement is ok final calendar week. The higher present problem after I install Matlab and KTEI for Model4200 of Keithley. Although I uninstall them, the problem even so exists.

I tried to uninstall and install all relevant sofe. But the trouble still bothers me.

I demand your help.

Thank yous very much.

Hello

I practise non know what is causing this problem, but at that place are some measures we can take to restore your organisation earlier installing the new software. This trouble is probably caused past registry keys over written by the new software.

First of all, yous demand to uninstall all software of NOR. And so, follow the instructions in the word document that I joined the. It will employ the MSIblast utility to clean all your registry keys.

Nosotros and then, navigate to your System32 folder and delete cvirte.dll and cvirt.dll of your organization files. Now, when reinstall us NI-VISA 4.iv, the software volition reinstall the correct versions of these files.

This process, you lot should get back to where you were earlier the offending software.

Thanks

Why does my browse of source memory run twice? * Keithley 2400 * SCPI *.

The purpose of my Half-dozen is to perform a browse of the voltage across 6 distinct features of solar cells both in the dark Land and with a light on. To do this, I'm commencement loading this scan on the Keithley 2400 and saving in the memory slot ane.

For some reason, the Keithley 2400 sweeps twice whenever I want to scan once. In other words, information technology makes dark 1 unit, then peripheral dark, 1 * delay *, calorie-free from the device 1 and and so peripheral light one...

I get only a data set up each time, so I know not what scan data are reported. This is important because reads the scan sometimes did something for the solar cell, and then I don't know if the information I collect is the kickoff or the 2nd sweep.

My VI and subVIs are attached, please take a look at them and give me your impressions.

Thanks

Keithley 2400 driver for Labview 8 does non

I sought advice and plant this commuter for a Keithley 2400, which must work with Labview 8.  I have Labview viii.6.

http://sine.NI.com/apps/UTF8/niid_web_display.download_page?p_id_guid=25B255F3AA83660EE0440003BA7CCD...

I put the driver file in the correct place and the vi are appearing in the pick menu, as expected.  I take my Keithley 2400 connected to a serial port COM1.  When I am trying to run the VI initialization it does non work.  I know that they are communicating in a form any because my Keithley goes into remote way and the driver initialization is able to read properly what is the model of the Keithley.  When he arrives at the VISA read vi is to elapse, it always returns the correct model identification.  I practice not understand why it is allowed and does not.

Is there anything else I should have installed?  The driver readme indicates the only additional software required is 3.two NI-VISA, but I take version 4.4, and so I should exist fine.  I don't empathize why it "kind of" works.  Whatever help would exist greatly appreciated.

You should check the endpoint used to point the end of a message from the instrument. The 2400 tin can utilize one of the 4 different endings:

I don't know which is the default. The commuter is written assuming that , although this should piece of work if the instrument is configured to utilize either or . If information technology is set up to i of the other 2 then you'll get a timeout on reading fault.
