Digital gas bath constant temperature oscillatorRelated fault handling:
1. Not heating: After confirming that the temperature controller is intact, it is usually due to damage to the heating tube, which can be replaced.
If the heating tube is in good condition and powered on, adjust the temperature to above room temperature to be in a heating state. First, observe if the heating indicator is on. If it is on, the relay on the temperature controller is damaged and can be replaced. If it doesn't light up, check if the temperature controller has a heating signal output.
2. Vibration not working: Adjust the speed knob to the maximum speed, use a multimeter in DC mode to check if the motor has voltage input. If the voltage exceeds 4-5V, consider whether the motor is faulty or if the belt is damaged. At the same time, it is possible that the mechanical part has rusted due to prolonged disuse. In this case, only manual assistance can be used to start. If there is no voltage and there is a low current sound, there must be a short circuit phenomenon. Generally, one or more rectifier components in the rectifier circuit are damaged. FirstDigital gas bath constant temperature oscillatorTurn off the power, disconnect the transformer from the drive power board, measure the fault point with a multimeter in the 1000 ohm range, replace the faulty component, and then restore the connection.
3. The speed display table shows no speed display. Check if the speed sensor is detached or if the sensor position is offset. Adjust it accordingly. If the display screen does not light up, it is usually due to a short power input line in the display circuit.
4. The digital gas bath constant temperature oscillator is not working: check if the fuse is broken, check if the power switch is damaged, or check if the power socket is plugged in properly.
5. Uneven temperature: Fan malfunction or foreign objects stuck in the fan blades.
