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)

When “ ” appears for over-range indication for any of V1, V2 and V3, this is displayed on the LCD. In
this case, the mark appears on all measurement screens on the W position.
