Alat ukur listrik multifungsi. Menampilkan 6 parameter sekaligus. Sangat Informatif.
Active power is calculated as: P = U I cos, cos represents the power factor, purely resistive loads (such as incandescent, heater, etc.) the power factor is generally close to 1, inductive and capacitive load load power factor 0-1; therefore purely resistive load test time, P is substantially equal to or close to U I; test inductive or capacitive loads (such as refrigerators, washing machines, televisions, computers, etc.) when, P Less than U I As for the specific number to keep the power factor related to power factor different for each appliance, please show table prevail.
Apply to power grid voltage range 110V-220V
Working voltage: 85 ~ 250VAC
Test voltage: 85 ~ 250VAC

Measurement accuracy 1.0
1. Short press the key, trun the backlight on or off
2. Long press for 3 seconds, enter the overload power Settings
2.1 enter the overload power set,factory default 4.4 KW
2.2 highest bit twinkle, short press the button corresponding numerical plus 1, long press 2 seconds is the shift, the biggest can be set up to 99.9 KW.
2.3 without any keystrokes operation,will exit and save the data after 5 seconds
3. Long press 5 seconds, the system reset, the accumulated electricity is cleared, the overload power setting to restore the default value
