Connection diagram 


1. Connect wires after verifying the operational voltage and allowed current.
2. During Connection, set the screw fastening torque at below 5kgf.
3. If the measurement value exceeds the measuring range, the Find will be shown "---"
4. The measuring instruments such as this product are weak to noise.
     If abnormal voltage(more than 1kV) occurs caused by a Power Relay, Magnet Switch, High-frequency equipment, 
     Reverse Electromotive Force, High-votage spark, and Lightning, use the line filter or the noise absorbing circuit in the exterior line.

Noise prevention by line filter

Noise prevention by varistor

5. Use the shield wire especially if the measuring input line is longer or a place with noise
