This procedure calibrates the voltage for voltage gain 1 and current range
low. Make sure that the shunt and the DC voltmeter are connected
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
INP
2. Set the conductance count to 0x15D
CAL
3. Set the input DC voltage to 10 Volts. After the input DC voltage
stabilizes enter the first exact voltage using following command
CAL
4. Set the input DC voltage to 500 Volts. After the input DC voltage
stabilizes enter the second exact voltage using following command
CAL
5. Send the calibration command to calculate the gain and offset:
CAL
6. Send the system error query command to make sure calibration was
successful.
