The balance that uses the electromagnetic force to balance the weight of the object is called an electronic balance . It is characterized by accurate and reliable weighing, fast and clear display, automatic detection system, simple automatic calibration device and overload protection. So what are the common problems and solutions for electronic balances? Electronic balance common problems and solutions : 1. Open the problem _ After opening, there is 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 work; AB-S/A8-1.4v ~50/60HZ6VA; PB-S/A9.5 -20VDC6W; AB/PB/GB9.5-14.5V50/60HZ1.5VA; (3) AC adapter burned, replace the AC adapter; 2, open the problem _ no display after the start (1) calibration data loss, recalibrate the balance; (2) transient interference effects; 3, open the problem _ open no display after all: the balance of the internal school, AB-S / A, PB-S / A; using the balance of the external school, AB / PB / GB / SB; (1) the balance placed environment is too bad wind The window is not closed, the environment of the balance is improved, and all windproof windows are closed. (2) Calibration features: AB-S/A balance after 1 hour preheating, do the first automatic calibration; the second environment is after the balance is opened for 2 hours; then the balance After 150 hours of power-on, on-time auto-calibration can be manually triggered (internal) at any time if needed. The PB-S/A balance is automatically calibrated after it is turned on, and the calibration can be triggered manually (internal school) if necessary. AB/PB/GB/SB 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 AB-S/APB-S/A balance display: When “CALL†appears on the display, it means that the balance is not working properly and needs to be an internal school. After completing the internal school, “CALL†will disappear automatically. 4, open the problem _ open no display after all (1) the environment placed on the balance is too bad to improve the environment; (2) the parameter settings in the balance menu is not good to adjust the menu, use the "RESET" function, correctly exit the menu, 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 microbalances†5, open the problem _ open after no display: (1) the environment placed on the balance is too bad: environmental factors include: vibration, airflow, temperature, external magnetic field, must improve the above environment, close the windscreen of the weighing room, the balance can work properly. (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 setting; 6Open the problem _ After opening, there is no display at all: 1. The water absorption and water release of the desiccant are formed. Airflow in different directions causes changes in air buoyancy, resulting in unstable weighing. The desiccant in the weighing chamber should be removed to maintain a stable weighing environment; 7 open problem _ no display after opening: (1) no weighing plate : After power off, first install the correct weighing plate, then turn on the balance; (2) said the disk is wrong: use the correct weighing plate that matches the balance (3) and the disk is in contact with the windproof ring: please find out the difference due to improper installation. The reason for reinstalling correctly.
