As a commonly used electronic weighing equipment, the operability and convenience of the hanging scale has brought great convenience to everyone's work, and has been praised by users. With the application of hanging scales in the market today, the varieties are also increasing. However, no matter whether they are imported or domestic, no matter what the type of electronic weighing scales are, no matter what the precision and quality are, their basic electronic weighing scales are all of the same structure, which is composed of: weighing pan, sensor, orientation detector PID regulator, power amplifier, low-pass filter, analog-to-digital converter, microcomputer, display device, chassis, feet, etc.
In the process of using the hanging scale recently, many customers have responded: "Why is there no response after the electronic hanging hook scale returns to zero? Today, the electronic weighing scale manufacturer comes to specifically solve the problem of no response after the hanging scale returns to zero.
1、 There is no measuring range after power on and no response after self check zeroing. Press and hold the "zeroing" key to power on and set the measuring range from the beginning. If it cannot be set normally, there is still no measuring range after power on from the beginning. It is recommended that the electronic weighbridge is basically determined that the memory chip is damaged. After replacing the element, set the measuring range from the beginning, and it needs to be calibrated from the beginning.
2、 The internal code is unstable or press the "Hold" key to display AD, and cannot jump to the internal code value. The internal code instability may be caused by poor contact or damage of capacitors C4 (CBB474) and N8 (4011) due to moisture or other reasons. This test can be repaired or replaced.
3、 The old version of remote control reception is bad, which causes the operation of single chip microcomputer to be disturbed, and the self check will not return to zero later; Sometimes, after zeroing, the visible graduation value automatically switches during weighing due to vibration, accompanied by some zeroing during weighing, resulting in serious errors and negative zero after the weight is put down.
