We detail the configuration of settings and viewing of metering data via the EV300 meter display.


Pressing the ‘‹›’ and ‘V/A’ simultaneously will take you to the metering screen mode or to the basic parameter settings, depending on what screen you were on.

How to View Energy Readings
  • Press ‘E’ to display/read different energy readings such as consumed energy (kWh), energy, reactive energy (kvarh), generated energy (kWh), etc.

Note: The information on this screen will vary depending on the model number and firmware version of your meter.

Figure 1: Consumed Energy

Ep= 38106.1 kWh. The maximum energy that can be accumulated is 99999999.9 kWh. After that the meter will roll over to 0.

How to View Measured Power
  • Press ‘P’ to display the real, reactive and apparent power, as well as the power factor and frequency.

How to Access Meter Settings

You can change settings from the meter’s display by going to the Setting mode. Press ‘‹›’ and ‘V/A’ simultaneously whiles on the metering screen mode to get to the settings mode.

In the setting mode:

  • ‘V/A’ can be used to confirm changes or go to the next screen
  • ‘‹›’ can be used to change a setting or enter edit mode. A digit will begin to flash in edit mode. When in edit mode:
      • Press ‘E’ to increase the value of the flashing digit
      • Press ‘P’ to decrease the value of the flashing digit
      • Press ‘‹›’ to switch the flashing digit
      • Press ‘V/A’ on the last digit to confirm the change; the cursor should stop flashing.

Once you are in the settings mode, you will be required to enter a password on the ‘PASS’ screen.

  • Enter your password or leave it as default ‘0000’ if it wasn’t changed.
  • Press ‘V/A’ to enter the system parameter settings mode.
