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.
● Do not use or store the tester in an area subject to magnetic fields or electric noises.
Unstable reading and measurement error may results.
● 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. AC Current Measurement with General CT
1) Press the power switch on the right side of the instrument.
2) Set the CT selector switch to the position.
3) Set the range selector switch to a range appropriate to the current to be measured.
4) Clamp the conductor of the circuit under test.
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.
Note: Clamp around only one conductor of the circuit to be measured.
