1 open question _ no display after opening
(1) There is no 220V current on the power outlet to turn on the AC outlet
(2) AC adapter error
Choose the 220V ~ AC adapter (external transformer) suitable for our 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

(1) Calibration data is missing
Recalculate the electronic balance
(2) instantaneous interference effects

Using the balance of the school, AB-S / A, PB-S / A
Using the balance of the outside school, AB / PB / GB / SB
(1) Electronic balance placed environment bad Windproof window is not closed
Improve the electronic balance of the placement environment, close all windproof windows
(2) calibration characteristics
AB-S / A balance 1 hour after the first warm-up, do the first automatic calibration; the second environment is open after the balance 2 hours; and then maintain the power balance after 150 hours, on-time automatic calibration if necessary, you can manually trigger Calibration (internal school).
The PB-S / A balance is automatically calibrated when it is turned on and, if necessary, the calibration can be triggered manually at any time. AB / PB / GB / SB can only be outside the school.
(3) calibration error
AB / PB / GB / SB with the wrong, the external weight of the school. When entering the outside school program, the balance will appear a flashing weight value, the use of this value of the weight of the outside school.
(4) AB-S / APB-S / A balance display at the top right of the "CALL"
When the display appears "CALL", the monitor makes the balance is now working, and need to do the school. After completing the school "CALL" will automatically disappear.

(1) The electronic balance placed in the environment is too bad
Improve the environment
(2) The parameters in the electronic balance menu are not set well
After recalling the menu, use the "RESET" function to exit the menu correctly and return to the factory settings
(3) weighing the room to keep the body temperature
Minimize this human factor
(4) the temperature of the object to be weighed is not equal to the balance
Place the sample beside the balance.
(5) samples exist water absorption, water discharge, static electricity, magnetic ... ... and other characteristics.
Refer to the METTLER TOLEDO balance for proper weighing / electronic analytical balance to overcome these effects in order to properly weigh and properly use the microbalance.

(1) the balance placed in the environment is too bad
Environmental factors include: vibration, airflow, temperature, external magnetic field, must improve the environment, close the weighing room of the windshield, balance to work properly.
(2) The parameters in the balance menu are not set well
After the menu is transferred, use the "RESET" function to exit the menu correctly and return to the factory settings

1, the desiccant of the water and water to form a different direction of the air flow, causing the air buoyancy changes, resulting in weighing instability
The desiccant in the weighing chamber should be removed to maintain a stable weighing environment
7 open the problem _ completely no display after opening
(1) not loaded plate
After the power, first installed the correct weighing plate, and then open the balance
(2) said the disk wrong
Use the correct title plate to match the balance
(3) said the disk and the wind collision
Due to improper installation of the reasons, please find out the reasons for re-correct installation.
