6514 using the buffer

I'm using the SCPI commands and writing my code in vb.net. Does anyone have any examples showing how to use the buffer to collect data until full, and then send it to my program?

Re: High resistance measurement with 4 point probe - Keithley 2400

I'm not sure I understand your reasoning for using a 4-wire resistance measurement. 4-wire measurements are used to eliminate the test lead resistance from your measurement, but in cases of G-ohm readings the leads are insignificant to the resistance you are trying to read.

Re: Checking connectors for contamination

You are correct. I forgot to mention that. Yes, I am using the SCPI commands to perform all setting changes and the readback the data.

Checking connectors for contamination

I'm trying to use a 6514 Electrometer to verify the assembly of a sample probe we build. The probe is used to measure 5G-Ohm samples during testing and maybe higher for our customers. We have been having trouble due possibly to contamination. I've manually used the 6514 to measure both good and bad ...
