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

ReFlex Power™
HPAL V
7.6.11
This procedure calibrates the voltage for voltage gain 1 and current range high.
Make sure that shunt and the DC voltmeter is 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 500.0V and maximum current 1.0
Amps
1. Turn the active load on:
2. Set the conductance count to 0x831:
3. Set the input DC voltage to 10 Volts. After the input DC voltage
4. Set the input DC voltage to 500 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
8. Reset the unit
