Operation Manual
1. Voltage measurement for power supply: insert the ammeter into electrical
outlets, repeatedly press "UP" or "DOWN" button to make the screen displays "AV”
and the unit shows “V”, figures on the screen show the real-time voltage of the power
supply (as shown below). This product can be used to measure and display
160~280V AC voltage (or 90~150V AC for US version).
2. Check electricity consumption: operate as above to make the screen display “EC”
and the unit shows “kWh”, figures on the screen show the electricity consumption (as
shown below). The ammeter displays amount in four decimals; when accumulated
electricity consumption is over 1kWh, it displays in pure decimal and integer
alternately. It can real-time measure and display 0.0001 ~ 999.9 kWh of electricity
consumption; if connect with electrical appliance of 1,000W, the last figure will
increase by one in about three seconds.
Moreover, with data storage function under power-down mode, all records won’t be
lost under long-time power down. Accumulated electricity consumption can be
cleared to zero by pressing “DOWN” button for 5~10 seconds, but the accumulated
electricity cost and running time will be cleared to zero at the same time.
3. Measure real-time running power: operate as above to make the screen display
“PW” and the unit shows “W”, figures on the screen show the real-time running power of
the appliance(as shown below).
4. Check electricity cost: operate as above to make the screen display “PC” on the
bottom and the unit shows “$”, figures on the screen show the electricity cost (as
shown below). This ammeter can real time measure the electricity cost for electrical
appliance; the smallest sub-display unit is “cent”. If electricity is priced at $0.6/kWh,
