DANGER

Do not use a current sensor outside of its rating or specifications.

Doing so may damage the current sensor or cause heat generation that could result in personal injury.

Do not measure currents that exceed the maximum input current.

Doing so may cause heat generation that could result in personal injury, fire, or damage to the instrument. The maximum measurable current of the current sensor will vary according to the frequency. Check the frequency derating characteristics in the current sensor’s user manual to determine the maximum input current.

1 Turn off the instrument.

2 Connect the current sensor to the current module by aligning the ▲ mark on the current module connector with the arrow on the current sensor connector.

Plug-in modules

Wireless modules

3 Turn on the instrument.

The current sensor will be automatically recognized by the instrument.

Attaching input terminal caps

Attach the included cap when not connecting a current sensor.

1 Attach the cap by aligning the ▲ mark on the current module connector with the protrusion on the cap.

Make sure the cap is securely attached to the top of the module.

2 Fold the cap back.

3 Insert the cap into the module connector.
