Verification
procedure
1. Enter CL50 Calibration mode.
Note
Ensure the correct current terminal is used for each
range.
2. Set the DMM to ACA mode. Press ACA. Ensure the
range is set to 500uA.
3. Input 200uA/70Hz.
4. Check the DMM display. If the current is within
specification, go to the next calibration range.
Range: 200uA±4 digits
