Why, electronic balance to range correction?
We weigh the items is to know its quality, but the internal data processing of electronic balance is on a weight basis, which relates to the acceleration of gravity, the acceleration of gravity with latitude and longitude, altitude change, W=M * G, (W for weight, M quality, G is the acceleration of gravity the changes of G, W) changes, it affects mainly the range change of electronic balance. So, the electronic balance in the installation, preheating after must be a range of electronic balance correction, in order to obtain accurate weighing results.
Why two, electronic balance is preheated?
Electromagnetic balance type electronic balance is composed of a sensor, a magnetic steel body, coil, a circuit board and other components, just when energized coil, circuit board components are fever, a moment can produce the change of the temperature, and the temperature variation will affect the electronic balance range and zero, also can cause when weighing data drift without stability. The electronic balance must have the preheating time, enough in the boot after the proposal: 1/100000 electronic balance (AUW-120D and AUW-220D) preheating for more than 120 minutes, 1/10000 electronic balance (AUW/AUX /AUY Series) preheated 30 - 60 minutes, 1/1000 electronic balance preheat for 30 minutes. If you want to lower the preheating time, speed up the balance of speed, can be in the preheating about glass doors open point (about 5 cm left and right). Electronic balance preheating after must do a range correction for the electronic balance, maintain accuracy of electronic balance weighing data.
Why electronic balance three, automatic correction of the frequent correction?
Frequent calibration is mainly the environment changes, the current location of automatic correction mainly has two kinds: temperature trigger (PSC) and time triggered (Clock-CAL, AUW-D only, AUW and UW). Time triggered in the electronic balance is arranged with three bit timing automatic calibration of electronic balance, and with the change of environment temperature trigger is not timing automatic calibration of electronic balance. Frequent is mainly the influence, so as to avoid temperature, temperature fluctuations may be placed more than 1/10000 of electronic balance room.
Four, how to avoid the frequent calibration and stability measurements?
To keep the balance of electronic balance weighing room temperature and humidity, avoid the strong convection air flow, avoid electronic balance surrounding vibration, avoid high temperature radiation. The other in the operation should pay attention to avoid the frequent hand in the weighing chamber import, otherwise easy to cause the unstable readings.
Five, electronic balance matters needing attention:
1, read before using electronic balance operation manual carefully to avoid misoperation brought to the electronic balance damage;
2, electricity before the horizontal transfer of electronic balance, placed on the tray, windproof ring, and then the electricity;
3, for the UW series, before switching on the power, should first transport screw electronic balance at the bottom of the counterclockwise rotation in the end, a good tune level, put on the pad and the tray, then electricity;
4, electricity for preheating, preheating the glass door slightly open point (electronic balance of about 5 cm, on more than 1/10000 of the amount of sense), can reduce the preheating time;
5, the preheating finished press operation manual for the electronic balance of the right range correction.
Simple fault treatment six, electronic balance:
1, AU series electronic balance:
CALE2: in the process of correction scale objects, remove objects;
CALE4: in the process of correcting weight is not accurate, use the right weight.
There are some fault treatment please refer to the operating instructions.
2, UW series electronic balance:
CALE0: this fault show that the electronic balance bottom transport screw not loosened, the electronic balance flip, will transport the screw press release direction (counterclockwise) rotation in the end, then energized.
