I wish to measure resistivity of a sample using Keithley238 current source and 2182. Is ther any sofware for what I can use them to make Delta Measurement.
I actually made a Labview program in which current is applied by 238 and voltage is read by 2182. But the problem is current is applied for a long time. I want to apply current in a very short time otherwise, long time current heat the sample, that is pelties effect.
Anyone can help me to get rid of this effect.
I need to measure Temperature from Ch2 soon after Voltage measurement from Ch1. The time between these two measurement should be as short as possible. I made a vi and I attached it.
Could anyone can check the vi and help me to solve this problem.
Thanks from now.

1. We do not have a software developed for the instrumentation you have to do Delta Mode measurement. We have a freeware for delta mode measurement using 6221A + 2182A. If self heating is an issue, you might want to check Keithley's pulse capabilities under 4200 Pulse (see link).

2. What you are trying to do can be done. It might be best to ask LV programming expert to debug your code.
