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 20.0V and maximum current
17.0 Amps.
1. Set the DC input voltage to 20 Volts
2. Turn the active load
3. Set the conductance count to 0xD5554.
4. After DC voltage stabilizes. Enter the voltage using SCPI
5. After DC current stabilizes. Enter the current using SCPI commands
6. Set the conductance count to 0x3CF3C.
