Testing DC Current
1. Connect ‘Calibrated Meter’ and ‘Meter Under Test’ to the CALMASTER
right sockets
2. Switch both meter to ‘DC mA’ range
3. Conrm that the ‘Meter Under Test’ mA reading is within ±5% of the
reading displayed on the ‘Calibrated Meter’
4. Log readings obtained for calibration records
5. Repeat above on all DC current ranges on the meters
