Testing equipment factory price temperature and humidity test box

Frequently Asked Questions:

1. When the temperature and humidity controller displays abnormal temperature;

Check steps:

1. Check whether the over-temperature protector of the control panel is set at the position of 150℃;

2. Check whether the circulating motor in the equipment room is damaged or not running;

3. Check whether the solid-state relay in the temperature part is burned out and short-circuited

If the heater is not burned out, use a three-meter meter AC voltage range, the voltage range is turned to the 600 volt position, place the red and black rods on the AC side of the solid state relay marked with the wire number T, and place the temperature part The temperature setting value is set to 0℃. At this time, the indicator light of the solid state relay in the temperature part will not light up. If the measured voltage value does not change, it remains below 10V, which means that the solid state relay burns out and shows a short circuit state.
