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 500V and maximum current 0.18
Amps.
1. Turn the active load on:
INP<n>:STATE 1
2. Set the conductance count to 0x15D:
CAL<n>:INP:COND:COUNTS 0x15D
3. Set the input DC voltage to 10 Volts. After the input DC voltage stabilizes
enter the first exact voltage using following command:
CAL<n>:INP:VOLT 1 <value-1
>
4. Set the input DC voltage to 500 Volts. After the input DC voltage
stabilizes enter the second exact voltage using following command:
CAL<n>:INP:VOLT 2 <value-2>
5. Send the calibration command to calculate the gain and offset:
CAL<n>:MEAS:OFFSET:CALC
6. Send the system error query command to make sure calibration was
successful:
SYST:ERR?
7. If there is no error returned at the system error query command then save
the calibration result:
CAL<n>:UNLOCK “6867”
CAL<n>:STORE
CAL<n>:LOCK
8. Reset the unit:
*RST<n>
