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 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 100.0 V and maximum current
0.5 Amps.
1. Set the DC input voltage to 100 Volts
2. Turn the active load
INP
3. Set the conductance count to 0xC7C.
