ULTRA LOW CURRENT
Measurement Setup
To prevent charging current due to residual cable or probe capacitance, you should limit the STEP
size to 100 mV. The B1500A has a built-in delay time on the low current ranges, and you do not
need to add extra time.
If the STEP is large, like the -500 mV for the first point in this sweep, simply add an initial hold time.
3 to 5 seconds should work fine. This has the effect of holding off measurement for a specified
amount of time, at the beginning point only.
Small STEP: 100 mV
Large HOLD TIME: 3 sec
