1. Maintenance of the instrument 1. The power supply for the instrument should be grounded separately, and it is forbidden to share ground with other equipment.
Grounding resistance ≤ 4W
2, the instrument should use lighting power, the power should be stable, no interference on the same power supply equipment;
It is forbidden to draw the 220V power from the three-phase four-wire for the use of the instrument. 3, because the human body has static electricity, so do not touch the IC chip on the motherboard by hand;
Replace or replace the motherboard should be stored in a shielding bag.
4. When the instrument is powered on, it is forbidden to plug in and plug in the peripheral cables and sensor cables behind the meter to prevent damage to the interface circuit.
Second, the maintenance of electronic truck scale (a) Note the use of electronic and electronic truck scale 1, electronic truck scale should be uniform on the scale platform, speed control in 5Km / h or less;
It is forbidden to perform emergency braking on the weighing platform and do a speed limit sign.
2, each vehicle before the scale platform to observe whether the instrument shows the gross zero;
Observe whether the meter display is stable before printing or recording data.
3. The location of the electronic truck scale installation should be avoided on the public passage as much as possible. Non-metered vehicles are prohibited from passing through the weighing platform at high speed.
4. When the vehicle is on the scale, it is not allowed to power off the instrument. If the power is cut off temporarily, the vehicle should be allowed to weigh down after resuming the power supply. After the instrument is restored to zero, it will be measured again.
5. It is forbidden to use electric welding on the scale platform or use the weighing platform as a ground wire.
6. Waterproof work shall be done in spring and summer, desiccant shall be placed in the junction box of electronic truck without foundation pit, and the sewer and drainage pipeline shall be kept open in the shallow pit pit.
7. When the temperature in winter is low, the meter will be energized for 20 minutes before metering.
8. The electronic truck scale of the food processing or food industry should do a good job of rat-proofing work. When the cable is broken, the joints should be waterproofed; the cable should be connected with a metal hose.
9. The vehicle load for each measurement must not exceed the maximum weight, but it should not be less than the 20d minimum weight.
10. Operators should not allow personnel who have not received training to operate the instrument.
11. The power of all weighing equipment should be cut off after work. It is strictly prohibited that the vehicle stays on the weighing platform for a long time.

In terms of service life, boron Carbide Nozzle has the longest service life. Such as forsandblasting and shot peening.Boron carbide costs more but will outlast tungsten carbide by 3 to 10times.
Electronic truck scale is a weighing and weighing equipment for weighing goods. Due to its features such as rapid weighing, high accuracy, digital data display, data transmission, and convenient operation and maintenance, it has completely replaced the old mechanical truck scale. The majority of users respected. Thanks to its unique plate-type modular mechanism, it is easy for users to choose the type of installation without foundation pits or shallow foundation pits. Widely used in metallurgy, mining, machinery, chemicals, ports and highway stations and other industries.
