Post by smith1987 » January 14th, 2019, 11:14 pm

Dear All,

Please help me to figure out , i have a keithley 2001 andKeithley 7002 (multiplexer) to measure 35 resistor sequentially with two scanner card, the existing program (without source code) is control both keithley device, in a measurement process it show the keithley 7002 run simultaneously (channel 1 and channel 6 run parallely. the rout scan should trigger the measurement process parallely betwen Channel 1 and Channel 6, this up counting process should start and stop in same time,let say the channel one in number 10 then LED in channel 6 also must stop at that position in sametime. please find the attachment file for reference. in attached - is refer to start position for channel 1 and 6 (red color) and stop (blue color) after that the process will continue with next measurement in channel 2 and 9 in start position ( green) and stop position (yellow). I'm really appreicate for whoever that help me to figure out this problem. Thank you

I see you attached the LabVIEW program (*.vi file). This would be the source code for what commands are sent to the 2001 meter and the 7002 switch, right? Can you look into the VI?

Also, from initial description with -, it sounds like you have expectation of the sequence of events as displayed by the lights on the 7002.
You did not explicitly indicate what is the problem. I guess that it simply no longer does the expected.

Try reboot the PC and restart the . Check the cables, especially if any trigger cable is connected between the 2001 and 7002. Examination of the code will tell you if it is using trigger to coordinate the meter with the switch.

Hi Andrea,

Thanks for your response, the problem is the existing program (compiled without source code) run properly with both keithley device (2001 and 7002) in simultan mode (for channel 1 & channel 6), and we want to make a new labview based software with simmilar process which is following the existing simultan process betwen one channel to another channel (1 and 6 & 2 and 7), the each led will turn on at the same time for the pair channel, but in the source code that i sent to you is only single channel process which is not working. Please let me know if you have any question. Thank you

Hi smith1987,
Sounds like you are asking for someone to write a new version of the program for you.
That would require a lot more understanding of the requirements and is typically performed by equipment owner.

Sounds like you need to just modify which switch channels are closed. Look at the “:rout:clos” commands.
The reference manual has command documentation and illustrations of using DMM with the Switch.

Hi Andrea,

Thank you for your reply, and yes I need to write a new software in LabVIEW simillar with existing program flow/sequence which is run simultaneously, may I know what command that can trigger two LED in different channel (channel One and channel Six) in same time?.

Thank you
