1-2 Warning Instruction for safe use
WARNING
To ensure that the meter is used safely, be sure to observe the
instruction when using the instrument.
1. Never use meter on the electric circuit that exceed 3.6kVA.
2. Pay special attention when measuring the voltage AC 30Vrms
(42.4 V peak) or DC 60V or more to avoid injury.
3. Never apply an input signal exceeding the maximum rating
input value.
4.
Never use meter for measuring the line connected with equipment
(i.e. motors) that generates induced or surge voltage since it may
exceed the maximum allowable voltage.
