7. Troubleshooting

• Display is blank: Ensure the monitor is securely plugged into a live wall outlet. If the backlight is off, it may be due to the monitor not being connected to AC power (backlight only lights when connected to AC).
• "OVERLOAD" warning flashes: This indicates that the connected appliance is drawing more than 3680W. Immediately unplug the appliance from the monitor to prevent damage to the device or electrical circuit. Do not use high-power devices with this monitor for extended periods.


Figure 7.1: The monitor displays an "OVERLOAD" warning when power consumption exceeds 3680W.

• Data not saving after unplugging: The monitor has a built-in battery for data memory. If data is not retained, ensure the monitor has been plugged in for some time to allow the internal battery to charge.
• Inaccurate readings: Ensure the appliance is fully plugged into the monitor and the monitor is fully plugged into the wall outlet. Avoid using the monitor with damaged outlets or extension cords.
