How to check whether the stainless steel electric heating tube works normally

1. When the stainless steel electric heating pipe is started, other lighting equipment connected in parallel with it will darken instantly, indicating that the electric heating works normally.

Power on inspection

2. If the leakage protection plug is connected, the red light is on when the leakage protection plug is loaded. At this time, the electric heating tube functions normally. When there is no load, the red light is not on and the electric heating tube is broken.

3. Use the resistance gear of a multimeter to measure the terminal marked "L, N electric heating". If the resistance is about 31 ohms, the electric heating tube is normal.
