3.11.15 EXTERNAL CAL FACTORS menu
Figure 4-28: External Calibration Factors menu
The EXTERNAL CALIBRATION menu provides access to the external input calibration
parameters. These parameters are password protected and can only be changed after the
calibration password has been entered. The PHASE key toggles between the calibration
screens for each of the three phase. Refer to the calibration section in this manual for details on
performing a calibration.
The following calibration factors are available from this menu:
Entry
Description
FS OUT
This value is set from 0 to 4095. It will set the External gain with the
ALC OFF. The external signal input must be set to the either 5.00
Vac in the EXT mode or +7.07 VDC in the RPV mode while the value
is adjusted for either 156 or 312 volts.
FS ADC
This value is to calibrate the converter used for the external input.
With the External signal set to either 5.00 Vac in the EXT mode or
7.07 Vdc in the RPV mode the value should be programmed for 312
in the high voltage range.
ZERO DC
This value is to calibrate the External Reference with the relays open.
It should be done before FS ADC and ZERO RMS. Enter the value of
zero with the relays open and press the ENTER key.
