DTAIL is also set to "OFF".

Zero-out Low Current Value (LOCUT)
Determines low current values to be zeroed out by specifying the threshold value in a
percentage to the dedicated CT type (CT) current value. The current values equal to or lower
than the specified value are deemed noise and therefore ignored. For example, if 0.6% (initial
value) is specified and the CT value is 100A, the values equal to or lower than 0.6A (i.e. 0.6%
of 100A) are all eliminated as noise.
The range of selection (Numeric input):
0.1 to 19.9%
Initial value: 0.6%
Note
The LOCUT setting is not possible when ETC is set to "OFF" and DTAIL is also set to
"OFF".

Measurement Range (RANGE)
Specifies the measurement range.
The range of selection (Options):
NORM / AUTO
Initial value: AUTO

The table below shows the resolutions (reference values) under AUTO setting.
* The reference value indicates a typical value, not a guaranteed value.
The measurement range cannot be specified when ETC is OFF and DTAIL is OFF.
