This procedure calibrates the voltage for voltage gain 2 and current range
high.
between the positive and negative lead of the active load. Also connect the
sense positive-to-positive lead and sense negative-to-negative lead.
This procedure requires maximum voltage 218V and maximum current 1.5
Amps.
1. Turn the active load on
2. Set the conductance count to 0x1999
3. Set the input DC voltage to 54 Volts. After the input DC voltage
4. Set the input DC voltage to 218 Volts. After the input DC voltage
5. Send the calibration command to calculate the gain and offset:
6. Send the system error query command to make sure calibration was
