Maintenance and maintenance methods of weighing instruments

1. Sun protection: direct sunlight should be prevented from shining on the black shell of the instrument, otherwise it may damage the instrument working environment beyond the rated temperature scale.

2. Waterproof: Under normal circumstances, although the humidity of the working environment of the instrument can reach 95%, dew condensation cannot occur regularly. Except for special stainless steel shell instruments with waterproof function.

3. Anti-corrosion: Corrosive substances can't penetrate into the instrument, otherwise it will corrode the equipment on the circuit board and the circuit board itself. Over time, the instrument may be invalidated. Even instruments with anti-corrosion function will have the same result if they are not tightly closed.

4. Lightning protection: Electronic weighing instrument belongs to weak current system, which is easy to be attacked by lightning and damage parts. Lightning mainly enters the instrument from two aspects: it is imported from the power line and imported from the scale via the signal cable. In normal weather, the operator only needs to operate the power switch, but in the case of close lightning strike, the instrument power plug and the signal cable plug of the scale must be unplugged. It is best to take lightning protection measures, such as adding surge protector in the instrument power supply circuit.

5. Anti-strong electricity: The power line of more than 220 volts accidentally hits the weighing platform or uses the weighing platform as the ground wire, and welding operation on the weighing platform may damage the instrument.

6. Anti-vibration: When the instrument is transported, it is best to put it in the tableland packing box or take appropriate anti-vibration measures.
