Electronic scales maintenance knowledge electronic scales are not allowed to repair
Beijing Heng electronic scales maintenance technical knowledge, so how much you understand the following simple maintenance knowledge.
1 electronic platform scales are not allowed to show the weight
Observe whether the internal code value is stable, whether the friction parts of the sensor, the power supply is stable, the op amp circuit is normal, A / D circuit circuit version is a foreign body, feedback resistance / capacitance / filter capacitor is bad or leakage.
Check if the sensor output signal value is within the standard.
In the absence of the standard, please refer to item 10 for compensation.
Use the weight to test whether the weighing scale of the weighing pan is even. (Please follow the instructions instructions, do weight correction).
2 electronic platform power can not boot after power
A, please first determine the fuse, power switch, power cord and voltage switch caused by the subject.
B, check whether the transformer AC110 / 220 input and AC18V output.
C, please remove the battery and then turn on the AC power to see if the battery voltage caused by the lack of. (Measuring the battery voltage, higher than 6V or more, lower than when you charge, if less than 5.5V, and charge soon after the power is not replaced when the battery).
Electronic scales repair electronic scales are not allowed, the electronic scale does not boot, electronic scales hops. Electronic balance, counting the electronic scale maintenance, to scale weight instability, the need for electronic scale maintenance can call 010-61732587 contact balance
