Description LCD large screen Six groups of data displayed on one screen 0.01 measurement accuracy Numerical display is more accurate High-precision chip control, precision SMT precision welding Self-contained shunt (transformer), direct power supply from the grid (220V) PC flame retardant material Comes with backlight (toggle switch) Clearly visible during day and night Specification Model: P06S-20/P06S-100 Name: Power Monitor Rated power: 20A/4500W,100A/22000W Maximum current: 20A,100A Working voltage: 80V-260V Test voltage: 50V-300V Frequency test range: 45V-65Hz Power test range: 0.01W~4500W/0.01W~22000W Power test range: 0.01W~9999kwh Voltage test range: 50V~300V Current test range: 0.01~20A/0.01~100A Voltage accuracy: 1% Current accuracy: 2% Power accuracy: 2% Product size: 89.5*54.5*28mm Digital display 100A with transformer, 20A built-in Package Inlcuded 1 Power Monitor Key Description 1. Short press the button to switch the backlight on and off 2. Long press for 3 seconds to enter the overload power setting 2.1. Enter the overload power setting, the factory default value is 4.4KW Overload alarm backlight and power flashing, automatically release when it is less than 2.2. The highest digit flashes, short press the corresponding number plus 1, long press for 2 seconds is the displacement, the maximum can be set to 99.9W 2.3. Without any key operation, exit after 5 seconds and save the data 3. Long press for 5 seconds, the system resets, the accumulated power is cleared, and the overload power setting returns to the default value Note: P06S-20 and P06S-100 are two different products and cannot be used in common The corresponding wiring method is also different. The threading direction must be the same as the arrow direction of the transformer. P06S-20 has a built-in shunt. If there is no power and power factor during work, it means the wiring method is wrong. Please check the wiring diagram. This watch does not support square wave power from battery DC power through inverter, sine wave inverter voltage can be used
