1) There is no 220V current on the balance power socket to connect the AC stand;
2) If the AC adapter is faulty, select the 220V~ AC adapter (external transformer) suitable for our work;
3) If the AC adapter is broken, replace the new AC adapter;
Second, open the problem - no display after opening 1) If the electronic balance calibration data is lost, please recalibrate the balance;
2) may be the impact of transient interference;
Third, open the problem - no display after opening: use the electronic balance of the internal school; use the electronic balance of the external school 1) the balance is too poor, the windproof window is not closed, improve the placement environment of the balance, close all windproof windows 2) calibration characteristics : After the electronic balance is warmed up for 1 hour, it will be *automatically calibrated; the second environment is after the balance is turned on for 2 hours; then after the balance is kept on for 150 hours, the on-time automatic calibration can be manually triggered at any time if necessary (internal school) ). The electronic balance is automatically calibrated after it is turned on, and the calibration can be triggered manually (internal school) if necessary. Some electronic balances can only be used in external schools.
3) Calibration error: AB/PB/GB/SB uses an incorrect external weight for external school. When entering the external school program, the balance will have a flashing weight value, and the weight of this value will be used for the external school.
4) “CALL†appears at the top right of the electronic balance display: When “CALL†appears on the display, the display makes the balance work now, and it needs to be an internal school. “CALL†will disappear automatically after the electronic balance is finished.
Fourth, open the problem - no display after opening 1) The environment in which the balance is placed is too bad to improve the environment;
2) After setting the parameters in the balance menu, it is not easy to adjust the menu. Use the “RESET†function to exit the menu correctly and return to the factory settings.
3) The body temperature of the hand in the weighing room is reduced as much as possible. 4) The temperature of the weighed object is not equal to the temperature of the balance. The sample is placed isothermally next to the balance.
5) The sample has characteristics such as water absorption, water repellency, static electricity, magnetic properties, and the like. Refer to “METTLER TOLEDO Balances for Correct Weighing/Electronic Analytical Balances to overcome the above effects for proper weighing and proper use of microbalancesâ€
Five, the balance open problem _ after opening, there is no display at all:
1) The environment in which the balance is placed is too bad: environmental factors include: vibration, airflow, temperature, external magnetic field, the above environment must be improved, the windproof window of the weighing room is closed, and the balance can work normally.
2) The parameter setting in the balance menu is not good: after loading the menu, use the “RESET†function to exit the menu correctly and return to the factory settings.
Sixth, the balance open problem - no display after the start:
1. The water absorption and release of the desiccant form airflow in different directions, causing changes in the buoyancy of the air, resulting in unstable weighing. The desiccant in the weighing chamber should be removed to maintain a stable weighing environment;
Seven, the balance open problem _ open no display at all:
1) The weighing plate is not installed: after the power is cut off, the correct weighing plate is installed first, and then the balance is turned on;
2) Weighing the disc: use the correct weighing plate that matches the balance. 3) The disc is in contact with the windshield: due to improper installation, please find out the cause of the collision and re-install it correctly.
How to handle the method that the electronic balance cannot be started
First, open the problem - no display after opening:
