What if the electronic scale is easy to crash?

LS2 Series - Barcode Label Scale

The electronic scale is a combination of modern sensor technology, electronic technology and computer technology. It is fast, accurate, continuous and automatic. The electronic scale is mainly composed of a load cell, an amplifying circuit, an AD conversion circuit, a single chip circuit, a communication interface circuit and a voltage stabilizing circuit. For ordinary users, the internal structure of the electronic scale is extremely complicated, and the problem is often overwhelmed. For example, how should the electronic scale suddenly crash? Here we will introduce some simple processing methods, of course, if it is a more complicated problem, you should look for professional electronic scale maintenance:

1. Check if the 220V power supply is normal;

2. Whether the voltage regulator circuits inside the electronic scale are normal;

3. Check if the power supply voltage of the printer is normal, and whether the current is too large when printing;

4. Check whether the voltage of the AD circuit is normal or not, otherwise check if the sensor is normal.

5. Check whether the digital circuit power supply of the circuit board is normal. Focus on the crystal oscillator components, which may be damp or damaged.

6, the electronic scale often crashes, mainly check the capacitive components on the circuit board, whether the capacity is reduced or leakage.

7. After the electronic scale is turned on, the digital instability or hop count is displayed. It belongs to the AD circuit or the sensor is bad. It is important to check that the voltage of this part must be stable and normal.
