6-5-2 Over-range indication/ Bar indication

WARNING

● When the over-range indication appears on the maximum chosen range, this means that the input exceeds

the maximum allowable input for the instrument. Never apply such an input to the instrument.

● When a measured value exceeds the maximum allowable input, the use of VT/CT’s is recommended. Refer

to “5-3 VT/ CT” and follow the instruction manual.

CAUTION

● When over-range indication appears on the screen, calculations are still performed. However their accuracy

may not be guaranteed.

● Over-range indication

The Over-range indication appears when the parameters (Voltage V, Current A, Active power P, Reactive

power Q, Apparent power S) exceed the following condition.

* Voltage V (V): >Voltage range selected x VT ratio x 130%

(e.g.: when voltage range is 300V and VT ratio is 1: 390.0V)

* Current A (A): > Current range x CT ratio x 130%

(e.g.: when current range selected is 200A and CT ratio is 2: 520.0A)

* Active power P (W)/ Reactive power Q (Var)/ Apparent power S (VA)

: > Power x VT ratio x CT ratio x 130%

(e.g.: when power is 60kW, VT ratio is 1 and CT ratio is 2: 156.0kW)
