Electronic balance show no reason analysis and solution
2014/10/27 Viewers:
Laboratory of electronic balance are precision instruments, customers often complain about the problem or the kind of problems, problems are generally need professional personnel to repair, our customers themselves can resolve itself? Electronic balance ordinary problems have no display after boot completely, the reason for all the detail of 7 common phenomenon without display the:
1, open problems _ after the opening, no video
(1) the balance placed poor environment to improve the environment;
(2) the balance parameter settings from the menu is not good in the menu, use the "RESET" function, the correct exit the menu, back to factory settings;
(3) left hand weighing chamber temperature to minimize the human factors
(4) were weighing body temperature is not reached and balance the sample placed in isothermal isothermal balance side.
(5) the presence of a sample water absorption, water, electrostatic, magnetic...... Characteristics. Refer to the "METTLER TOLEDO - United States balance correctly weighing / electronic analytical balance, overcome the influence, use the right to correct the weighing and microbalance"
2, open problems _ after the opening, no video:
(1) the balance placed poor environment: environmental factors include: vibration, air flow, temperature, external magnetic field, the environment must be improved, close the windproof window weighing room, balance to work properly.
(2) the balance parameter settings from the menu is not good: into the menu, use the "RESET" function, the correct exit the menu, back to factory settings;
3, open problems _ after the opening, no video:
1, water absorption and water form the desiccant flow in different directions, caused changes in the buoyancy of the air, resulting in instability should be weighing, weighing chamber desiccant removed weighing environment to maintain stable;
4, open problems _ after the opening, no video:
(1) not fitted with said plate: after power failure, first install the known correct disk, then open the balance;
(2) called knotted: with the right in line with the balance of the said disc
(3) called the disc and the windproof ring collide: due to improper installation produced, please find out the reasons against the re installed correctly.
5, open problems _ after the opening, no video:
(1) the power socket is not connected to AC base 220V current;
(2) the AC adapter error, select the 220V~ AC adapter for our work (AC); AB-S/A8-1.4v~50/60HZ6VA; PB-S/A9.5-20VDC6W; AB/PB/GB9.5-14.5V50/60HZ1.5VA;
(3) the AC adapter burned, replace the AC adapter;
6, open problems _ after the opening, no video
(1) calibration data loss, re calibrated balance;
(2) the instantaneous interference;
7, open problems _ after the opening, no video:
Using the internal calibration scale, AB-S/A, PB-S/A; using the school scales, AB/PB/GB/SB;
(1) the balance placed poor environment windproof window is not closed, improve the balance place environment, close all storm window
(2) calibration features: AB-S/A balance for 1 hours after preheating, do the first automatic calibration; second environmental balance was open 2 hours; and then the balance to maintain state power after 150 hours, punctual automatic calibration if necessary, may at any time to manually trigger calibration (in school).
(3) calibration error: AB/PB/GB/SB error, external weights for school. On entering the school program, the balance will appear a flashing numerical weights, using the numerical weights for the school. (4) the AB-S/APB-S/A balance display right over the "CALL": when the "CALL" appears in the display when the display to make balance now work not, need to do in school. Done within the school after the "CALL" will disappear.
We must consider the precision grade in the purchase and use of electronic balance. The weighing range requirements: electronic balance in addition to its precision, also should see whether the largest weighing scale to meet the needs of. Usually the maximum load plus a little insurance coefficient can be, which is commonly used to load and then relax, bigger is not better.
