4. METHOD OF MEASUREMENT
4-1. Measurement of AC Line Current (
～
A)
①
Press the power switch "ON".
②
Set the range selector switch to the proper
ACA range to be measured.
Start the measurement at top range and
then work down to lower range.
③
Open the CT and clamp it to the conductor
to be measured at the center of CT.
Close CT completely.
④
Read the current value on the display.
⑤
If you make measurements in a dark place
or in a place where it is difficult to see the
readings, use the data hold switch. Fig.1
Note : Clamp around only one conductor of the circuit to be measured. (See Fig.1)
When making the clamp measurements for high AC current, the noise sound
of CT may be caused, however, this is not abnormal.
