LCD Power Meter 2 Tariff Backlite

This household power monitor can measure various parameters: power (W), electric energy (KWH), voltage, ampere, power factor, cost, minimum and maximum power. It is very suitable for energy consumption monitoring. The plug of the power meter is equipped with 3.6V rechargeable battery (Ni-MH) to store electric energy, which allows the meter to move and view without losing readings

The dual-tariff electricity meter is used to measure the electricity consumption of household appliance and calculate electricity costs.

The product has built-in rechargeable battery, for the newly purchased device or the device that has not been used for a long time, please connect the power supply for charging.

If the display and the key reaction are unusual, you can press the "RESET" key to reset the system. After the reset, all data is reset to 0, you have to reset the parameters. 

Installing the batteries

Install 3.6V rechargeable Battery (NI-MH) . The purpose of the batteries is to store the total electricity and memory setting.

Resetting

If an abnormal display appears or the buttons produce no response, the instrument must be reset. To do this press the RESET button.

Display Mode

Entire LCD can be displayed for about 1 minute and then it automatically gets into Model. To transfer from one mode to the other, press the FUNCTION button.

Mode 1: Time/Watt/Cost Display Display duration(how long) this device connect to power source. LCD on first line shows 0:00 with first two figures mean minutes (2 figures will occur while occur at 10 min) and the rest shows seconds. After 60mins, it displays 0:00 again with first two numbers means hour(2 figures will occur at 10hours) and the rest shows minutes. The rest can be done in the same manner which means after 24 hours, it will re-calculate. LCD on second line displays current power which ranges in 0.0W~9999W. LCD on third line displays the current electricity costs which ranges in 0.0cost~9999cost. It will keep on O.OO cost before setting rate without other figures.

Mode 2: Time/Cumulative electrical quantity Display Display duration(how long) this device connect to power source.

LCD on first line shows 0:00 with first two figures mean minutes(2 figures will occur while occur at 10 min) and the rest shows seconds. After 60mins, it displays 0:0() again with first two numbers means hour(2 figures will occur at 10hours)and the rest shows minutes. The rest can be done in the same manner which means after 24 hours, it will re-calculate. LCD on second line displays current cumulative electrical quantity which ranges in 0.000K WH 〜 9999KWII without other figures. LCD on third line displays ''DAY''— "1 "will be showed on numerical part(thc other three figures will be showed at carry) which means it has cumulated electrical quantity for 24hours(one day). The rest can be done in the same manner until the maximal cumulative time of 9999 days.

Mode 3: Time/Voltage/Frequency Display  LCD on first line displays the same as Mode 1 dones. LCD on second line displays current voltage supply (v) which ranges in 0.0V~9999V .LCD on third line displays current frequency (HZ) which ranges in 0.0HZ~9999HZ without other figures.

Mode 4: Time/Current/Power Factor Display LCD on first line displays the same as Mode 1 dones.

LCD on second line displays load current which ranges in 0.0000A~9999A. LCD on third line displays current power factor which ranges in 0.00PF 〜 1 .OOPF without other figures.

Mode 5:Time/Minimum Power Display LCD on first line displays the same as Mode 1 clones. LCD on second line displays the minimum power which ranges in 0.0W~9999W. LCD on third line displays character of "Lo" without other figures.

Mode 6: I,ime/Maximal Power Display LCD on first line displays the same as Mode 1 dones. LCD on second line displays the maximal power which ranges in 0.0W~9999W. LCD on third line displays character of "Hi" without other figures.

Mode 7: Time/Price Display LCD on first line displays the same as Mode 1 dones. LCD on third line displays the cost which ranges in O.OOCOST/KWH 〜 99.99COST/KWH without other figures.

Overload Display: When the power socket connects the load over 3680W, LCD on second line displays the”O VER LOAD” with booming noise to warn the users,( 60470733, 60469303,selectable choice)

Supplemental informations:
1: Except to OVERLOAD , ' interface, LCD on first line display time in repitition within 24hours.
2: LCD on first line, second line or third line described in this instruction take section according to two black lines on LCD screen. Here it added for clarified purpose.
3. Mode 7 will directly occur while press down button "cost".
4. “UP”&''Down" are in no function under un-setting mode.

Dual tariff setting:

Dual tariff means that there are 2 different unit prices for the electricity costs, used for time-sharing billing area.

When the time runs on the time corresponding to tariff 1, the electricity costs are calculated according to the unit price of tariff 1.

When the time runs on the time corresponding to tariff 2, the electricity costs are calculated according to the unit price of tariff 2.

Press the "COST" button continuously for 3 seconds to enter the tariff setting.

Press the "UP' button to select dual tariff (DUAL TARIFF) as shown on LCD display.

Backlight Mode:
Connect to AC power, backlight in mediately light, if not press any button, backlight will went off in 15 seconds.
When press any of the buttons backlight start light again. (Backlight only light when it connect to AC power, backlight cannot light if use battery)

Setting Mode

1. Electricity price setting
After keeping COST button pressed lasting more than 3 seconds(LCD on third line display system defaults price, eg O.OOCOST/KWH ),the rendered content begins moving up and down which means that the device has entered the setting mode. Then press FUNCTION button to change selection and press UP/DOWN to set what you want. (On pressing once, the figure after domical point will increase or decrease accordingly. On pressing and hold-on, figures after demical point will increase or decrease slowly in 2 seconds while figures change quickly when hold-on time exceeds 2 seconds. When hold-on time reaches 10 seconds or more, the figures after demical point will stop while the figures before demical point begin to increasing or decreasing.) After that, press FUNCTION fbr swithing, then press “UP'nd "DOWN" button again to set value which ranges in OO.OOCOST/KWH 〜 99.99COST/KWH. After setting all above, press COST to return to Mode7 or it will automatically return to Mode7 without any pressing after setting with data storage.
