How to do well in the protection of electronic truck scale in plum rain season

When you are using the electronic truck scale, you find that a certain place is affected with moisture and has a fault. The display value on the weighing display instrument is very disordered and the reading is floating irregularly. What should we do after finding this problem?
Introduction to waterproof and maintenance measures of electronic truck scale:
① Disconnected connector: If the sensor cable or the cable of the junction box has been reconnected due to disconnection, the sealing device shall be used to seal the connection.
② Timely drainage: The electronic truck scale using shallow foundation pit foundation shall regularly check whether the drain outlet is blocked and whether the drainage equipment operates normally. In case of heavy rain, we shall have a special operator to drain the water in the tank.
③ Check the connector of the cable: all terminal connections should not be loose.
④ Check whether the junction box of the electronic truck scale is affected with damp: first, check whether it can be used normally. If it cannot be used, please do not dismantle it without authorization and call a professional technician for inspection.
⑤ Whether the electronic truck scale has angle difference: put the same weight on the position of each sensor of the weighbridge to see if there is a big deviation. If it is necessary to adjust the adjustable rheostat in the junction box, use a small screwdriver to turn it to the same position. This operation requires professional technicians.
⑥ Check whether the weighing is accurate: if not, please call the maintenance personnel to adjust the measuring range or recalibrate.
⑦ Whether the displayed weight of the electronic truck scale weighing instrument is consistent: if the displayed value has a large error with the actual value, please do not dismantle each circuit without authorization, otherwise the loss will be greater.
⑧ Check whether the sensor is immersed in water: if the electronic truck scale weighing instrument cannot return to zero, the display is unstable, the weighing is inaccurate and other faults are caused by the serious immersion of the sensor in water, the sensor needs to be replaced, please consult the professional maintenance personnel.
⑨ Whether there is water in the instrument: If there is rainwater floating into the instrument, causing electrical circuit break and burning the instrument, please turn off the power immediately and call the professional maintenance personnel for replacement, otherwise it cannot be used normally.
Since summer is the season of frequent lightning, we should also pay attention to the lightning protection of electronic truck scales. In fact, many electronic truck scales are struck by lightning because the lightning protection wiring is not well done, so the more effective and direct way to prevent truck scales from being struck by lightning is to keep the normal wiring of all parts. In order to prevent lightning, we can operate according to the following protective measures.
① : We usually set lightning rods at high places to connect with the earth, so that lightning strikes will not endanger our equipment and personal safety at the right time.
② Check the grounding of the whole scale platform: the whole scale platform shall be grounded, and the scale body shall be connected to the grounding pile with one or several grounding cables. The grounding pile shall be driven in the zero zone with constant potential, and the grounding resistance shall be less than 4. There is a spacious large current return channel between the scale platform and the grounding pile, so when static induction occurs, electrons can be added from the ground to make the balance, and the equipment can be quickly evacuated without damaging the scale after generating high potential.
③ : Check whether the weighbridge is struck by lightning: the electronic truck scale damaged by lightning is relatively obvious and easy to find. If some components damaged by voltage breakdown are found to be blackened, some bulge or even burst, it is necessary to report to the company for timely replacement of parts to avoid normal operation in the later period.
