1.
MODE
Press and select the AC/DC mode.
2. When using a current sensor,
conversion to the CT mode is required.
3.
CURREN
When
is pressed, “Auto A-Range” will be displayed on the LCD.
4.
In the above stage, each time you press “RANGE,” the range of an electric current will change.
To select an electric current, press “
RANGE” five consecutive times and “-CT-” will be displayed
on the LCD.

5.
Apply a voltage to the V and COM terminals of HPM-300
6.
Connect the + terminal of an electric current to HPM-300A’s Hi-Current, and the – terminal to
the 15A terminal
7.
When connecting an electric current to a load, the electric current value will be displayed
8. The voltage and electric current will be displayed on the LCD, and the electric power,
electric power usage, and power factor will be converted and displayed whenever you
press “POWER.
9. In the above state, when measuring the electric power usage, pressing “ENERGY” will start
the accumulation of the electric power usage. Pressing “POWER” will lead to conversion to
the Wh mode and will display the accumulated electric power usage.
10. When trying to stop the operation, press “ENERGY” again to stop it
11. The electric current value can also be confirmed by using only an electric current sensor
without the need of applying a voltage
