2. Check according to each group of voltage marked on the power socket bracket, if not, repair the power supply

3. Check pins (30) on main board AT89S52, if there is no high frequency impulse, replace the crystal oscillator 20MHz at main board AT89S52.

4. Check if the pin between the display panel and the main board is plugged well.

Display instability

1. The sensor shall be plugged properly with good contact. For discrete type, check if the two connecting wires are broken.

2. Check whether the sensor works well

3. Check if the steel tube of the sensor is connected well with the machine grounding wire or the enclosure

Breaking light constantly on

1. Check if the output clamp is broken

2. Check if the printed board of the heat sink is broken

3. Check if the machine plug-ins are loose or jumped out

4. If the discrete connecting wire is disconnected.

Shell-touching lamp constantly on

1. Check if the clamp wire touches the enclosure or the stainless steel tube

2. Check if the printed board of the heat sink is broken

3. Check is the resistance 5.1Ω-0.5W of enlarge board is broken.

Big error

1. If the sensor is matched with the machine

2. Whether the sensor works well

3. If related measuring conditions comply with other precautions
