This procedure calibrates the resistance 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. Connect the
sense positive-to-positive lead and sense negative-to-negative lead. Also
connect the shunt and the DC current meter between the active load and
DC power supply
This procedure requires maximum voltage 500.0 V and maximum current
0.5 Amps.
1. Set the DC input voltage to 500 Volts.
2. Turn the active load on:
INP<n>:STATE 1
3. Set the conductance count to 0x246:
CAL<n>:INP:COND:COUNTS 0x246
4. After DC voltage stabilizes, enter the voltage:
CAL<n>:INP:VOLT 1 <value-1>
5. After DC current stabilizes, enter the current:
CAL<n>:INP:CURR 1 <value-1>
6. Set the conductance count to 0xF9:
CAL<n>:INP:COND:COUNTS 0xF9
