How to check measurement after field installation
Frequently Asked Questions
① After installing the product in the field, check the measured value when receiving power to check the normal state.
② Press the MENU ( ) KEY on the initial screen.
③ Use the UP ( ), DOWN ( ) key to select ‘DISPLAY’ and then input the RIGHT ( ) Key.
④ Use the UP ( ) and DOWN ( ) keys to select ‘FUNDAMENTAL’ and input the RIGHT ( ) Key to check the
voltage measurement.
⑤ Use UP ( ), DOWN ( ) KEY to check other measurements.
⑴ Although the circuit breaker is open, UVR contact output is not operating.
- If you go to the UVR setting category, there is a DEAD BLOCK setting.
Check the settings and change them according to the site conditions.

LCD Display Display Description & CAUTION
•Check measurement in order of 'Phase voltage', 'Line-to-line & Sequence
voltage', 'Current', 'Power factor', 'Active power', 'Reactive power',
'Apparent power', 'Voltage Unbalance', 'Current Unbalance', ‘Load Rate&Thermal’.
•In a normal case, the magnitude of voltage and current may be different,
and the phase should be displayed with a value similar to the example shown
above for normal wiring.
•A phase voltage is the standard for phase display, and the magnitude of voltage/
current/power indicates the primary value to which RATIO is applied.
•In the case of a directional element, since it operates with the magnitude
and phase of voltage and current, malfunction or non-operation may occur
if it is not in the normal phase.
•If the measured value is out of phase, check the primary wiring and the VT,
CT secondary wiring.
