(1) “OL†is displayed on the electronic balance display.
Cause of failure: The weighing of the electronic balance has exceeded the maximum load.
Solution: Reduce the load and do not exceed the maximum load to weigh
(2) "UL" is displayed on the display of the electronic balance.
Cause of failure: The weighing of the electronic balance is under load.
Solution: Carefully check the weighing plate of the electronic balance or the weighing pan balancer, etc., to see if it is not placed or not placed.
(3) When the display of the electronic balance is not lit.
The reasons for the failure are: 1 the power is not connected or the external power is off; 2 there is a problem with the transformer connection; 3 the transformer is damaged; 4 the balance is not turned on.
Repair method: 1 If the power is not connected, you can check whether the plug, wire, etc. are disconnected or poorly connected, and remove it; 2 connect the transformer correctly; 3 replace the transformer of the same specification; 4 turn on the balance.
(4) The display value of the electronic balance constantly changes.
The causes of the failure are as follows: 1 the balance is not level, the inclination is too large; 2 the installation environment of the balance does not meet the requirements; 3 the scale of the bending tester is volatile or moisture absorption; 4 the difference between the scale and the room temperature is large.
Adjustment method: 1 adjust the electronic balance to make it level; 2 select a qualified installation environment and work surface to install the electronic balance; 3 use the vessel to hold the volatile or moisture-absorbing items for weighing, effectively prevent the evaporation of the scaled items and Moisture absorption; 4 The scale is placed in the weighing room for necessary constant temperature treatment, and then weighed.
(5) If the display result of the electronic balance is obviously wrong.
The reasons for the failure are as follows: 1 The electronic balance is not peeled (or peeled); 2 is not adjusted horizontally; 3 is not corrected for a long time; 4 balance is not accurate; 5 environmental impact.
Repair method: 1 pay attention to the tare weight during the weighing process; 2 carefully check the balance to make the electronic balance level; 3 should regularly correct the balance, especially before the accurate weighing; 4 If the balance corrects the inaccurate roughness meter, it can correct the problem or perform external school processing and linear adjustment; 5 should avoid the influence of temperature, airflow and humidity on the balance.
(6) If the electronic balance has no display or only a dash.
Cause of failure: The stability of the electronic balance is set too sensitive.
Repair method: Reset the stability of the electronic balance to make it suitable.
(7) The electronic balance calibration shows a blinking bending tester.
The cause of the failure: 1 balance is not serious; 2 balance installation environment does not meet the requirements; 3 use the external school weight that does not meet the requirements.
Adjustment method: 1 Adjust the horizontal level of the electronic balance; 2 Install the electronic balance on a stable table and ensure that the environment meets the environmental requirements of the electronic balance; 3 Avoid using an external calibration agitator weight that does not meet the requirements, or redefine After that, correct it again.
