After we have used the radar level gauge for a period of time, we need to repair the radar level gauge to ensure that there is no malfunction during the use of the radar level gauge. So, what should be paid attention to when repairing the radar level gauge?First of all, if we use a multimeter to test the radar level gauge, then we must not conduct a live check, otherwise it will cause damage to the radar level gauge. Moreover, if we use a logic pen or an oscilloscope to check the signal of the radar level gauge, we must be careful not to touch the probes of the two measuring needles at the same time, otherwise there will be a short circuit.Secondly, in the process of detecting the filter capacitor of the radar level gauge power supply, the positive and negative electrodes of the electrolytic capacitor should be short-circuited first, and the electrolytic capacitor can play a role in discharging. But it should be noted that it is easy to burn the core wire without using the probe wire to discharge. In addition, to detect the radar level timing in a humid environment, a multimeter needs to be used to check whether the points are unobstructed.Finally, in the process of detecting the radar level gauge, do not plug in various control boards or plugs, because this will cause strong induced electromotive force when the control board is plugged and unplugged, and damage the control board and plugs.These are the issues that everyone should pay attention to when testing the radar level gauge. Although it is very important to check the radar level gauge on a regular basis, everyone must master the correct method to ensure that there will be no other problems while the radar level gauge is checked.
