2. Design Parameters
Power
Measuring Range: 0 - 1250W; Resolution: 1W; Accuracy: 1% ± 1 digits
Accumulative Energy Consumption
Measuring Range: 0 - 99999.9kWh; Accuracy: 1% ± 1 digits
LCD Display: For readings < 10000.00 kWh, the LCD display reads 0.00 - 9999.99kWh; for readings > 10000.00 kWh,
the LCD display reads 10000.0 - 99999.9kWh. If the accumulative energy consumption value exceeds 99999.9kWh,
the LCD display shows 99999.9kWh until you erase it from the memory.

Overload Indication
If the current exceeds 10A for more than 2 seconds, the Power Meter will enter Overload Indication mode and the
display will show
"OL". After the Power Meter enters Overload Indication mode, it will stay in this mode if you do not
press any button. If you press a button, the Power Meter will return to normal operation.
Note: Within the first two seconds after the display just shows “ OL ”, the Power Meter does not respond to any
press of button. The Power Meter will respond if you press a button after the first two seconds.
