This procedure calibrates the resistance for voltage gain 1 and current
range high. Make sure that the shunt and the DC voltmeter are connected
between the positive and negative leads 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 50.0V and maximum current 0.5
Amps.
1. Set the DC input voltage to 50 Volts
2. Turn the active load on:
INP
3. Set the conductance count to 0x18F9:
CAL
4. After DC voltage stabilizes, enter the voltage:
CAL
5. After DC current stabilizes, enter the current:
CAL
6. Set the conductance count to 0x9DB:
