1. Measure real-time voltage of the power supply 160~280V AC;

2. Measure real-time operation power of the appliances (0~3000W);

3. Show the power consumption (0~9999kWh);

4. Calculate the cost of energy according to the pre-set price of energy (0~$9999); price of

energy can be pre-set to the local price by users;

Two ways for calculating power consumption and power cost: electricity consumption and

electricity cost in single operation period and accumulated electricity consumption and

electricity cost in all operation periods; can be manually cleared to 0.

5. Operation condition monitor: The indicator light will flicker when the real-time ratio of

operation condition reaches its alarm point.

Ratio of operation condition is the ratio between accumulated operation time per hour

(running power is over preset standby power) and 1 hour.

Alarm point for ratio of operation condition and standby power can be pre-set.

6. Show the operation time of appliances (0~24h~9999d)

Two ways for calculating operation time: time in single operation period and accumulated

time in all operation periods; can be manually cleared into 0.
