High-resistance measurement with the 3237, 3238, and 3239
QI use the 3237, 3238, and 3239 to perform high-resistance measurement, but at and above 5 MΩ measured values vary widely. Is the instrument broken?
A
I’m unable to use USB communications with the LR8431.
QI purchased an LR8431, installed the Logger Utility, and connected the instrument to my computer with a USB cable, but the computer won’t recognize the LR8431.
