This procedure calibrates the resistance for voltage gain 4 and current
range high. 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 10.0 V and maximum current 1.0
Amps.
1. Set the DC input voltage to 10 Volts
2. Turn the active load
INP:STATE 1
3. Set the conductance count to 0xFFFF.
CAL:INP:COND:COUNTS 0xFFFF
4. After DC voltage stabilizes. Enter the voltage using SCPI
commands
CAL:INP:VOLT 1
5. After DC current stabilizes. Enter the current using SCPI commands
CAL:INP:CURR 1
6. Set the conductance count to 0x7878.
CAL:INP:COND:COUNTS 0x7878
