*: Set the range switch of the sensor to 500 A when the current range of this instrument is set to 500 A or
50 A.
Selecting an appropriate current range
Set the current range based on the anticipated maximum load current that will generate during the
measurement. (Refer to the operating status, load rating, breaker rating, and other data to make
this determination.)
If the range is too low, then an over-range current will be generated during measurement, and
accurate measurement will not be possible.
And if the range is too high, then errors will increase and accurate measurement will not be possible.
