• 1.Short press the button to switch the backlight ON or OFF.
• 2.Long press 3s to enter the over-load power setting:
• (1)The over-load power value defaults 4.4kw; over-load alarm backlight and power flashing, it will auto-release when less than 4.4kw.
• (2)The highest bit is flashing, short press the corresponding number plus 1; long press 2s to shift, 99.9KW is the maximum values can be set.  
• (3)After 5s exit and save the data if without any operation.
• 3.Long press 5s, system reset, cumulative power zeroing, over-load power setting restore default values.

• 1. The total power resistive load of the connected appliances cannot excess the rated power, otherwise it will be damaged, even fire.
• 2. 20A electrical tester is built-in shunt, if it doesn't display power and the power factor, means the wiring connection is wrong, please check the wiring diagram.
• 3. Except for the wires, other objects should not be inserted into the connection hole; tightening the screws.
• 4. No waterproof function, only used in dry indoor environment.
• 5. Far away from children and fire.

• 1 x Wiring Type Electrical Tester ( Digital Multimeter )
