Coulombs Measurements
Step 6
Connect the charge to be measured to the electrometer
Basic connections for amps measurements are shown in Figure 5-1.
NOTE
See “Connection Basics” in Section 2 for fundamental information on making con-
nections to the electrometer input.
Step 7
Take the charge reading from the display
If using auto discharge, use the REL key to zero the display when the integrator resets.
Remember that Rel was enabled in Step 5. Therefore, you will have to press REL twice. The first
press disables Rel, and the second press re-enables it to zero the display. See “Auto Discharge
Hop” in “Coulombs Measurement Considerations” (in this section).
