Laboratory electronic balances are precision instruments. Customers often complain about such problems or problems. Problems often require professional personnel to repair. Can our customers solve their own problems? The common problems of the electronic balance have no display at all after booting. The following gives you a detailed explanation of the reasons for the 7 common phenomena without display:
1, open the problem _ open no display at all
(1) The environment in which the balance is placed is too bad to improve the environment;
(2) After the parameter setting in the balance menu is not well loaded into the menu, use the “RESET†function to exit the menu correctly and return to the factory settings;
(3) The human body temperature in the weighing chamber is minimized. (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€
2, open the problem _ open 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 entering the menu, use the “RESET†function to exit the menu correctly and return to the factory settings;
3, open the problem _ open no display at all:
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;
4, open the 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 disc: use the correct weighing plate (3) that matches the balance. 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.
5, open the problem _ open no display at all:
(1) There is no 220V current on the power socket to connect the AC battery;
(2) AC adapter error, choose 220V~ AC adapter (external transformer) suitable for China's work; AB-S/A8-1.4v~50/60HZ6VA; PB-S/A9.5-20VDC6W; AB/PB/GB9. 5-14.5V50/60HZ1.5VA;
(3) The AC adapter is burned and the AC adapter is replaced;
6, open the problem _ open no display at all
(1) Loss of calibration data, recalibrate the balance;
(2) Instantaneous interference effects;
7, open the problem _ open no display at all:
Use the balance of the internal school, AB-S/A, PB-S/A; use the balance of the external school, AB/PB/GB/SB;
(1) The environment where the balance is placed is too poor, the windproof window is not closed, the environment of the balance is improved, and all the windproof windows are closed. (2) Calibration characteristics: After the 1st preheating of the AB-S/A balance, the first automatic calibration is performed; The secondary 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 (internal) at any time if necessary.
(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 AB-S/APB-S/A balance display: When “CALL†appears on the display, the display makes the balance work now, and it needs to be an internal school. After completing the internal school, “CALL†will disappear automatically.
We must consider the accuracy level when purchasing and using an electronic balance. Requirements for the range of symmetry: In addition to the accuracy of the electronic balance, it should be noted whether the maximum weighing meets the needs of the range. Usually take the maximum load plus a small insurance factor, that is, the common load can be relaxed, not the bigger the better.
