4. Kullanım Talimatları
4.1. 8 Display Modes
The watt meter features 8 display modes to show different measured data. Press the "MODE" button to cycle through the modes.

- Mod 1: Cumulative Time, Apparent Power (VA), Active Power (W)
- Mod 2: Cumulative Time, Cumulative Electrical Quantity (kWh), Electricity Bill (Cost)
- Mod 3: Cumulative Time, Voltage (V), Frequency (Hz)
- Mod 4: Cumulative Time, Current (A), Power Factor (PF)
- Mod 5: Cumulative Time, Minimum Power (W), Maximum Power (W)
- Mod 6: Cumulative Time, Overload Alarm (W), Cumulative Time (Day)
- Mod 7: Cumulative Time, KWH Alarm (kWh)
- Mod 8: Cumulative Time, Price (Cost/kWh)
4.2. Overload Settings
The default overload power is 3680W. It is recommended to set this to 1800W for typical US household use to prevent overloading circuits.
- Press and hold the "MODE" button for more than 3 seconds to enter the overload settings.
- Press the "MODE" button to select the digit location you wish to change.
- Use the "UP/CLK" and "DOWN" buttons to adjust the digits to the desired overload value (e.g., 1800W).
- Press the "SET" button to save the overload setting.

4.3. Electricity Price Settings
Set the cost per kilowatt-hour (kWh) to accurately calculate electricity bills.
- Press and hold the "SET" button for 3 seconds to enter the electricity price setting mode.
- Press the "MODE" button to select the digit location.
- Use the "UP/CLK" and "DOWN" buttons to set the numbers for your electricity cost per kWh.
- Press the "SET" button to save the price settings.

4.4. KWH Alarm Settings
Configure an alarm to be notified when a specific cumulative kWh consumption is reached.
- Press and hold the "DOWN" button for 3 seconds to enter the KWH alarm setting mode.
- Press the "MODE" button to select the digit location.
- Use the "UP/CLK" and "DOWN" buttons to set the desired KWH alarm value.
- Press the "SET" button to save the KWH alarm settings.
4.5. Button Sound Settings
Turn the button press sound on or off.
- Press the "MODE" button and the "DOWN" button simultaneously to toggle the button sound on or off.
4.6. Backlight On/Off and Time Settings
Control the backlight for better visibility and adjust its duration.
- Manuel Açma/Kapama: Press the "DOWN" button to manually turn the backlight on or off.
- Adjust Backlight Time: Press and hold the "UP/CLK" and "DOWN" buttons simultaneously to enter backlight time setting. Use "UP/CLK" and "DOWN" to select the duration (bL-0 = 10 minutes, bL-1 = 1 hour, bL-2 = 4 hours, bL-3 = 8 hours, bL-4 = normally on). Press "SET" to save.

4.7. Veri Hafıza Fonksiyonu
The device automatically saves all cumulative data and settings.
- When the meter is removed from the socket or the appliance is unplugged, all setting data and cumulative data (electricity quantity, cost, unit price, time) are saved.
- Upon reconnection, the last saved data will be displayed (excluding current, voltage, power, power factors, which are real-time readings).
- This function also protects data during sudden power failures.

4.8. Data Clear Function
Clear all cumulative data (kWh, cost, and total time data).
- Press and hold the "MODE" button and the "UP/CLK" button simultaneously for 3 seconds.
- All cumulative data will be cleared to zero.
4.9. Sıfırlama İşlevi
Reset the power meter to its default factory settings, clearing all data.
