VII. Other Items and Notes:
1. Exclusiveness of Current Clamps
There are three current clamps attached to every meter, which can not be
exchanged for the other meters. Current clamps should be prevented from
any crush and kept clean in order to ensure reliability when closing up to
measure.
2. Maintenance of Current Clamps
Please clean up clamp jaw surface after measurement, soft cloth coupled
with lubricant (eg: WD-40 lubricant) instead of rough cloth or the corrosive
are expected to use for the clearing. Please clean again just before use.
3. The meter can be used to measure secondary circuits and low voltage
loop, however, not suggested to measure current in high-voltage circuits in
case of electric shock.
