Hpal Voltage Calibration - Part Ii Ofv - Ametek Elgar ReFlex Power Operation Manual

ReFlex Power™
HPAL V
7.6.9
This procedure calibrates the voltage 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. Also connect the sense positive-to-
positive lead and sense negative-to-negative lead.
This procedure requires maximum voltage 109V and maximum current 6.0
Amps.
1. Turn the active load on:
2. Set the conductance count to 0xCCCC:
3. Set the input DC voltage to 27 Volts. After the input DC voltage stabilizes
4. Set the input DC voltage to 109 Volts. After the input DC voltage
5. Send the calibration command to calculate the gain and offset:
6. Send the system error query command to make sure calibration was
7. If there is no error returned at the system error query command then save
8. Reset the unit
