※ 1: Compared to measurement input range, higher measuring voltage needs a multiplier and lower measuring voltage needs a shunt.
※ When using voltmeter and ammeter simultaneously, connect the separated power supply each.
※ (-) terminal of the power and (-) terminal of measurement input are shorted.

Cautions during Use

1. Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.
2. 5VAC, 12-24VDC power supply should be insulated and limited voltage/current or Class 2, SELV power supply device.
3. Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting the power.
4. Keep away from high voltage lines or power lines to prevent inductive noise.
In case installing power line and input signal line closely, use line filter or varistor at power line and shielded wire at input signal line.
Do not use near the equipment which generates strong magnetic force or high frequency noise.
