The Elto Multifunction Power Meter is a device designed to measure and display various electrical parameters for household appliances. It is intended for indoor use only and should not be plugged into other meters.

Function Description

The power meter provides a comprehensive overview of electrical consumption and performance. Its primary functions include:

Current Clock Display: Shows the current time, with an option to switch between 12-hour and 24-hour modes.
Line Voltage Display: Measures and displays the current line voltage.
Line Current Display: Measures and displays the current line current.
Line Power Display: Measures and displays the real power being consumed.
Accumulative Total Electric Quantity: Tracks and displays the total accumulated kilowatt-hours (kWh).
Total On-Time and Electric Charge: Records the total time an appliance has been on and the corresponding total electric charge.
Price-Specific On-Time and Electric Charge: Allows for tracking of on-time and electric charge for two different price settings (Price 1 and Price 2), useful for varying electricity tariffs.
Line Frequency Display: Shows the current line frequency.
Power Factor Display: Displays the power factor, indicating the efficiency of power usage.
Adjustable Price/kWh: Enables users to set the cost per kilowatt-hour for accurate charge calculation.
Day and Block-of-Day Combinations: Offers flexible scheduling options for price programs, including individual days (MO, TU, WE, TH, FR, SA, SU) and various combinations (MO,TU, WE, TH, FR; MO,TU, WE, TH, FR, SA; SA, SU; MO, TU, WE, TH, FR, SA, SU).

The device cycles through various data displays by pressing the "FUNC." button: VOLTac → AMP → WATT → KWh → TOTAL PRICE; TOTAL ON TIME → PRICE1 → PRICE2. It initially displays the current clock, line voltage, and frequency upon power-up after battery insertion. Subsequent presses of the "FUNC." button reveal line current and power factor, real power and power factor, accumulative KWh and power factor, total on-time and total electric charge, total on-time and electric charge for Price 1, and total on-time and electric charge for Price 2. Holding the "FUNC." button for 5 seconds clears accumulated total electric quantity and total electric charge when displaying total electric charge or price-specific charges. An "OVER" message will flash if the total electric quantity or charge overflows.

Press "SET" once; "WEEK DAY" flashes. Use "UP" to set the day.
Press "SET" again; "HOUR" flashes. Use "UP" to set the hour.
Press "SET" again; "MINUTE" flashes. Use "UP" to set the minute.
Press "SET" again to return to clock display mode.
To switch between 12-hour and 24-hour modes, press "UP" during clock display.

Setting Price of Cost/kWh: This feature allows users to program two different electricity tariffs.

Press and hold "FUNC." for 5 seconds during voltage, current, or power display.
Setting Price 1:
- Press "SET" once; the first digit of "COST/kWh" flashes. Use "UP" to set the digit.
- Repeat pressing "SET" and using "UP" for the second, third, and fourth digits.
- Press "SET" again; the radix point flashes. Use "UP" to adjust its position.
- Press "SET" again; the weekday flashes. Use "UP" to select the desired day combination for this price.
- Press "SET" again; the hour of "ON TIME" flashes. Use "UP" to set the hour when this price becomes active.
- Press "SET" again; the minute of "ON TIME" flashes. Use "UP" to set the minute.
Setting Price 2: After completing Price 1 settings, press "FUNC." once and release. Repeat the steps for Price 1 to set Price 2.

Appliance Connection: The meter should be plugged into a standard 240V power outlet. An appliance should then be plugged into the meter's outlet. It is crucial not to plug in appliances with a load exceeding 10 Amp (2400W). Ensure the appliance's plug is fully inserted.

Maintenance Features

Cleaning: If cleaning is required, the meter must be removed from mains power. It should then be wiped with a dry cloth.

Standby Mode: The LCD display will turn off after 10 seconds of no operation when AC power is disconnected. Pressing any key will reactivate the display.

Important Safety Warnings:

Do not plug two or more meters together.
For indoor use only.
