Common electronic platform scale fault problems and solutions
[ Time:2021-02-04 Number of views:6118 ]
Common electronic platform scale fault problems and solutions:
1, boot without any display, sound: from the circuit analysis, "no display" is the fault of the display circuit, no sound is the fault of the buzzer circuit. The probability of the two faults occurring at the same time is very low. So the general fault occurs in the power supply circuit.
2. Weight is not allowed: Observe whether there is friction in each part of the sensor, whether the stabilized power supply is stable, and whether the operational amplifier circuit is normal. Whether there are foreign bodies on the circuit board of A/D circuit.
3, poor display: boot to observe whether there are bad conditions on the normal LCD, if not, it can be determined that the LCD is bad; Check CPU connectors for oxidation, cold welding, or short circuit. Check whether there is short circuit between the CPU and the LCD.
4, the battery can not store electricity: first determine the fuse, power switch, power line caused by the problem; Check whether the transformer has AC110/220 input and AC18V output; Check whether the diode of the PIN attachment at the input end of the transformer is normal; Replace the battery.
5, the electronic can not charge or the charging indicator is not quantity or no response: please first determine whether the electronic 110V/220V voltage switch is adjusted to the same voltage as the use of the power supply, and determine that the charging line has been firmly inserted in the charging base on the scale; Check whether the charging cable is broken by external factors; Check whether the fuse is bad; The battery is faulty.
6, the key no action or action is often automatically triggered: the key is bad; Key socket is faulty.
7, electronic said can not be weighed to full load: electronic said protection screw is not removed; Electronic said whether there is foreign body infiltration caused interference or impact, fall injury; Whether the internal procedure Settings of the electronic scale are correct.
The above is Changzhou Youbao for you to share a few points about the electronic platform scale fault phenomenon and treatment, welcome to pay attention to our official website. Learn more about weighers.
