■Precautions on preparation before use

⚫ Observe the use conditions and environment requirements for installation place. ⚫ You must set up the instrument before use. Read the manual carefully to set it up correctly. If the setup is

incorrectly done, the instrument will not be properly operated.

⚫ Check the power rating of the instrument and then apply proper voltage.

■Precautions on how to use ⚫ When operating the instrument, check that active bare wires do not exist around it. If any bare wire existed,

stop the operation immediately and then take appropriate action such as insulation protection.

⚫ If a power outage occurred during the setup, the instrument would not be set up correctly. Set it up again

after power recovery.

CAUTION

⚫ Do not disassemble or modify the instrument to use. Otherwise, a failure, an electric

shock, or a fire can be caused.

⚫ Use the instrument within the rating specified in the manual. If you used it outside the

rating, it might cause not only a malfunction or failure of the instrument but also ignition or burnout.

⚫ Do not open the CT secondary side while the primary current is energized. When the CT

secondary side circuit is open, the primary current flows. However, the secondary current does not flow. Therefore, a high voltage is generated at the CT secondary side and the temperature rises, resulting in insulation breakdown in the CT secondary winding. It may lead to burnout.

⚫ When external equipment is connected to the external terminals, the instrument and

external equipment must not be powered and be used after the definitive assembly on a cabinet door.

⚫ The rating of the terminal of external equipment should satisfy that of the external

terminal of the instrument.

Mode

Description

Reference

Operating mode

This is a normal operation mode to display each measured value in digital

numerical number. In the operating mode, there are ‘Present value display’ that shows values at present and ‘Max/Min value display’ that shows the

maximum and minimum values in the past. In addition, on each display screen, the cyclic display mode, which automatically switches the display screen every 5 seconds, is available.

5 Operation

Setting mode

This is a mode where you can change the settings for measurement and output functions. In addition, on the CANCEL screen, which is the screen to cancel the setting change, the following special operations are available.

・ Restart the instrument. ・ Reset the settings to the factory default.

3 How to Set up

Setting confirmation mode (Test mode)

This is a mode where you can confirm the setting of each item. In this mode, you cannot change the setting. Therefore, it is possible to prevent from accidentally changing the setting. The mode also provides test function available at startup of systems. ・ Communication Test: Without measurement (voltage/current) input, fixed

numerical data is returned.

・ Analog output adjustment: Analog output adjustment is executed such as

zero adjustment or span adjustment.

・ Output test: Without measurement (voltage/current) input, alarm/digital

output, analog output, or pulse output is executed.

・ Support function for checking input wiring: ・ When either a voltage input or current input is incorrectly wired, the

incorrect wiring part is displayed on the screen. In addition, useful information is also displayed such as a current phase angle and voltage phase angle.
