(5) Move onto the measurement display.
1. Press the
PT・CT・SC
or
EXIT
key, and the SHIFT indicator will turn off. The
SC indicator (scaling) is lit.
2. The range setting corresponds to the secondary side of the voltage and
current transformers. For example, with the 150 V, 5 A ranges, the ranges
(resolution) of the scaled voltage, current, active power, and other values is
as follows.
