● Changing Set Values
Set the parameters while the Power Monitor is in a Setting Mode
However, even if the set values are changed, the changes will not be applied in the Setting Mode.
Changes to parameters that are made in a Setting Mode are enabled by changing to
Measurement Mode.
● Communications Example for Write Parameter Area
Here, the Special CT type is set to 50A.
(It is assumed that the Power Monitor is already in a Setting Mode.)
