4. Using a multi-meter, test the actual string voltage and enter this value under
[Real U]
5. Press

To perform a Discharge Current Calibration:
This option calibrates inner current and outside current. Inner current calibration is for the built-
in current sensor, while outside current calibration is for optional external current clamp. For
current calibration, you will need an adjustable current clamp as current standard.
Inner Current Clamp Calibration:
1. Select
[Inner I calib]
in the
[Measure calib]
menu
2. Connect the adjustable current clamp on the red or black load cable
3. Press the
up
arrow on the load bank panel until the current value in current clamp is
higher than 70% of load bank maximal discharge current. For example, for a load bank
of 48V 300A, the current value in the standard current clamp should be higher than
210A.
4. Use the
left/right
arrow key to input the current value in
[Real I]
(from the current clamp
equipment) to modify the load banks
[Test I]
value.
