Lpal Resistance Calibration - Part Ii Ofv - Ametek Elgar ReFlex Power Operation Manual

Active Loads
LPAL R
7.6.28
This 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 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 1.0
Amps.
1. Set the DC input voltage to 10 Volts
2. Turn the active load
3. Set the conductance count to 0xFFFF.
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 0x7878.
