This procedure calibrates the voltage for voltage gain 8 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 54V and maximum current
11Amps.
1. Turn the active load on:
2. Set the conductance count to 0x33333:
3. Set the input DC voltage to 13 Volts. After the input DC voltage
4. Set the input DC voltage to 54 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
7. If there is no error returned at the system error query command then
8. Reset the unit
