The fluctuations are too large. After the typhoon, there was a power outage once; once power was restored, the supply started to fluctuate
The typhoon is really strong; haha, check whether there’s water intrusion or any issues with the wiring. Also, examine the grounding and power supply systems
Pay special attention to checking the insulation of the electrode circuit; moisture or water intrusion can easily lead to unstable insulation, thereby affecting the stability of measurements.
1: Check whether the excitation voltage is normal. 2: Check whether the coil resistance is normal. 3: Check for internal leakage in the electrodes.
It’s very likely that water has gotten in. Check it right away. If it is used in this way continuously, it will get damaged permanently and cannot be repaired.
It’s very likely that water has gotten in or it has become damp. Check it right away.
Everything is fine; it was taken apart for inspection and there were no issues, it’s just the fluctuation. . Fatal fluctuations
If there is no water inflow, check the grounding wire connection carefully.
Reset to factory settings and try resetting the parameters, such as increasing damping or reducing sensitivity. If the problem persists, there may be an issue with the circuit board
