Product Description
Get KETOTEK power consumption meter to help you monitor and control the electricity usage
KETOTEK watt meter can help you check the quality of power by monitoring voltage, amp, frequency and power factor. Helping you find power-wasting appliances so you are able to decide whether it is worth keeping.
Functions:
Multiple measurement function: Watts, Current, Voltage, Frequency, Power Factor, VA (apparent power), Max/Min power, Accumulated Time, Power Consumption, Cost.Time calculated: The device is calculated for the time it actually works (working power and standby power less than 2W are not counted in the time).One-click check function: Simple 5 buttons switch interface to display different parameters.3 kinds of alarm function: Overload Alarm, KWH Alarm, Cost Alarm. You need to set the parameters before using.Memory function: Save data automatically (power consumption, electricity cost, cumulative time, alarm parameters), avoid data loss due to a sudden power outage.Data deletion function: Press and hold + and – for 3S to clear accumulated data but keep previous parameter settings.Reset function: Press and hold ↺ for 3S to restore factory settings, both accumulated datas and parameter settings will be deleted.ABS flame retardant shell, which is tough, hard and high temperature resistant.
Save power energy and save money on bills
3 Kinds of Alarm Functions
1. Overload Alarm(3680W default), you need to set the overload power to 2900W before using.
2. KWH Alarm(0.000-9999KWH Adjustable )
3. Cost Alarm(0.00-9999COST Adjustable )
When the datas reaches set value, the screen will display “OVERLOAD”, “KWh ALARM” or “COST ALARM”, LED indicator will flash to warn the user.
Data Storage Function
Built-in chip that retains measurement data and settings even in the event of a power outage. Don’t worry about data loss caused by sudden power outage. Just plug the meter into a power outlet and plug your device into the meter. Easily measure power consumption and cost of appliances.
Real-time Monitoring & Saving bills

Press M and hold for 3S to enter setting mode. Select the Cost/KWH mode, enter the utility providers cost of electricity so you can easily identify which appliance in your home is costing you the most money.
Ideal for many appliances, such as refrigerator, washing machine, air conditioner, computer, dishwasher, microwave etc.
NOTE:
1. The consumption and time will NOT be measured and counted when:
Your device is in standby or not working.The rated power of your device is smaller than 2 watt.
2. What data will be saved?
Electricity quantity, cost, electricity cost, cumulative time. (But NOT save current, voltage, power, power factors)
3. If there is an abnormal display or the buttons produce no respond, please reset the electric meter.
4. The power of electrical appliances can not exceed 2900W. The default overload power is 3680W ( 0-3680W adjustable ). In general, you need to set the overload power to 2900W before using.
5. This energy monitor is not suitable for monitoring the charging of new energy vehicles. When using a charger for a new energy vehicle, it is necessary for a professional to inspect the home wiring and install a dedicated circuit with an RCD.

Suitable for computers, games consoles, printers, TVs, refrigerators, washing machines, dryers, routers, etc.
【One-click switching interface】Choosing from 5 button to quick access different parameters. Press M to display KWH and electricity cost. Press + to display Watt (active power) and VA (apparent Power). Press OK to display true RMS voltage Vrms and true RMS current Arms. Press – to display Hz (frequency) and PF (power factor). Press ↺ to display the maximum and minimum power. Press OK for 3s to display the complete accumulated time.
【Multiple protection】When the load power exceed the overload setting value, power consumption exceed KWH alarm setting value, electricity cost exceed cost alarm setting value, LCD displays “Overload”, “KWh ALARM” or “COST ALARM” and LED light flashes continuously to warn user. The default overload power is 3680W (0~3680W adjustable). In general, you need to set the overload power to 2900W before using. Ideal for monitoring the energy consumption of household appliances.
