The following 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 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 50.0 V and maximum current 2.0
Amps.
1. Set the DC input voltage to 50 Volts
2. Turn the active load on:
3. Set the conductance count to 0x7FFF:
4. After DC voltage stabilizes, enter the voltage:
5. After DC current stabilizes, enter the current:
6. Set the conductance count to 0x3C3C:
7. After DC voltage stabilizes, enter the voltage:
