This procedure calibrates the voltage for voltage gain 1 and current range
low.
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 500.0V and maximum current
0.2 Amps.
1. Turn the active load on
2. Set the conductance count to 0x15D
3. Set the input DC voltage to 10 Volts. After the input DC voltage
4. Set the input DC voltage to 500 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
