9. Characteristics of the Clamp Sensor (Electric Current Sensor)
An electric current sensor can be used for measuring electric power consumption without blocking or
connecting a circuit. This sensor is equipped with a fireproof and electric-shock-free case for hand
protection in compliance with the safety standards.
An electric current sensor must be separately purchased.
① Procedure for Use
1. Connect the + terminal of the electric current sensor to HPM-300A’s Hi Current, and the – terminal
to the 15A terminal.
2. When the electric current measurement cable is positioned exactly in the middle of a sensor, the most
accurate measurement value can be obtained.
3. The value flashed on the screen is the value of the RMS current running through the cable
(1A = 1mV).
② Caution
Measurement cannot be done when more than two cables are connected.
③ Safe Usage
1. Do not use a probe with a more-than-AC-600V cable.
2. This equipment enables the simultaneous measurement of a high electric current in a high-pressure
cable up to 1000A (using an electric current sensor). The inappropriate operation of the equipment can
cause casualties.
3. Using the equipment with a cable with damaged coating is very dangerous, and careless contact with
the equipment can cause electric shock. Make sure to wear rubber boots when using the equipment,
and use it on a rubber floor with verified insulated products. Normal operation in a grounded state
must also be maintained to ensure safety.
4. Do not open or repair the equipment’s case while operating the equipment.
