The following procedure calibrates the resistance for voltage gain 8 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
10.0 Amps.
1. Set the DC input voltage to 10 Volts
2. Turn on the active load
INP
3. Set the conductance count to 0xD5554.
