When the current power is smaller than overload power, it will stop alarm._x000D_ 2.P06S-20 and P06S-100 are different products, which cannot be used in the same way! Because they adopt different internal principles and designed in different structures. You should use the correct wiring method corresponding to the product. The damage of the product, caused by wrong wiring, will not be covered in warranty!_x000D_ 3.Model P06S-100 product must be connected with an external mutual inductor in normal operation. Threading must follow the arrow of the mutual inductor! No power and power factor after operating indicates wrong wiring. Please refer to the wiring diagram!_x000D_ _x000D_ Cautions:_x000D_ 1.The sum of load power of the electric appliance connected with the product should not exceed rated power, or the product will be damaged, even resulting in fires._x000D_ 2.The product doesn't have waterproof function, so please use it under dry environment. Prevent splash water when using it near a bathroom, a kitchen, a fishbowl, etc._x000D_ Keep it away from children and fire; do not plug any foreign matter rather than a wire in the connection hole; please fasten the screw._x000D_ 3.Do not disassemble the product without permission._x000D_ _x000D_ _x000D_ _x000D_ Package Included:_x000D_ 1 x 6 in 1 Voltage Meter _x000D_ _x000D_ Note:_x000D_ _x000D_ Please allow 1-3cm differs due to manual measurement. _x000D_ Due to the different display and different light, the picture may not reflect the actual color of the item. Thanks for your understanding.
