Voltage and current calibration is performed at the factory.
The EMS−UGK does not require calibration. If you choose to
recalibrate, the original calibrated values will be lost.
To recalibrate the settings, click the

EMS System Calibration page.
NOTE
For optimal results, verify that the circuits are loaded to nominal load levels prior to
starting calibration. Have qualified service personnel (such as a licensed electrician) obtain
the physical measurements using a multimeter and RMS current probe. For calibration,
measure the L−N voltage (not L−L voltage).
Enter the voltage and current measurements from the installed
panel(s) on the EMS System Calibration page. Blank fields will not
be calibrated.
NOTE
To revert any changes made on the current page back to default settings before
saving, click
