5. METHOD OF MEASUREMENT
5-1 Measurement of Leakage Current
5-1-1 Leakage current measurement for the grounded conductor
1) Set the power switch to “ON” position.
2) Set the range selector switch to arrange appropriate to the current
to be measured.
3) Clamp the conductor of the circuit under test with the current transducer.
4) In a dark place or where it is difficult to read the readings, use data hold switch.
5-1-2 Leakage current measurement for single phase or three phase electric circuit
1) Set the power switch to “ON” position.
2) Set the range selector switch to arrange appropriate to the current
to be measured.
3) To measure leakage current in single phase electric circuit, clamp the two
conductors together. Clamp the three or four conductors together in case of
three phase electric circuit.
4) In a dark place or where it is difficult to read the display, use data hold switch.
5) To cut off the influence of high frequency, use filter switch.
6) After measurement, set the power switch to “OFF”.
5-2 Measurement of Line Current
1) Set the power switch to “ON” position.
2) Set the range selector switch to arrange appropriate to the current
to be measured.
3) Clamp the conductor of the circuit under test.
* Note: Clamp around only one conductor in the circuit to be measured.
4) Read the displayed value.
5) In a dark place or where it is difficult to read the readings, use data hold switch.
6) After measurement, set the power switch to “OFF”.
CAUTION:
This tester is designed for low voltage applications.
To avoid electrical shock or damage, the measurement is limited to the circuit
under 600V AC.
●
Never make measurement for uninsulated conductors or bus bars.
