5. METHOD OF MEASUREMENT
5-1. Preparation and Caution before Measurement
●Before making measurements, install the batteries. Two LR-44 batteries can be
used.
●Avoid using the tester in places subject to high temperatures, humidity or
excessive vibration.
●Before measurements, be sure the data hold switch is set to "OFF". (It is
impossible to make measurements if the data hold switch is set to "ON".)
●Remove the battery if the tester will not be used for a long period of time.
5-2. Measurement of Leakage Current
5-2-1 . Leakage current measurement for the grounded conductor
1) Set the power switch to "ON" position.
2) Set the range selector switch to a range appropriate to the current to be measured.
3) Clamp the conductor of the circuit under test with the current transducer.
4) 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.
5-2-2. Leakage current measurement for the single-phase or three-phase electric
circuit.
1) Set the power switch to "ON" position.
2) Set the range selector switch to a range appropriate to the current to be measured.
3) To measure a leakage current in a single-phase electric circuit, clamp the two
conductors together. Or clamp the three conductors together in the case of the
three-phase electric circuit.
4) 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.
