Rear-panel verification
The following topics describe verification procedures that are done with connections attached to the
terminals on the DMM6500 rear panel.
DC current 10 A range verification
To verify 10 A range:
1. Set the TERMINALS switch to
REAR
.
2. Press the
FUNCTION
key and select
DC Current
.
3. Press the
HOME
key.
4. Set the range to
10A
.
5. Connect the DMM6500, reference DMM, calibrator, and amplifier as shown in the following figure.
Ensure cabling is designed to conduct 10 A without significant voltage drop. In general,
cables for the 10 A range steps should be made of heavy gauge wire and should be as short
as practical.
