Precautions for using electronic balance, hydrostatic electronic balance

Four points to note when using electronic balances Four points to note when using electronic balances.


The first is to warm up in advance. Electronic balances usually need to be warmed up before use, and the warm-up time of each balance is often different. Generally speaking, the higher the accuracy level of the balance, the longer the warm-up time is required. Preheat, if necessary, extend the preheat time (usually the lower the ambient temperature, the longer the preheat time). In fact, many users use the balance out of the box, which cannot guarantee the weighing performance of the balance. Therefore, the warm-up of the electronic balance is the key to accuracy.


The second is environmental conditions. Environmental conditions are also an important factor affecting the measurement performance of electronic balances. If no special temperature limit is specified in the operating instructions of the electronic balance, the balance should work normally at the temperature of -10 ℃ ~ 40 ℃; if a special temperature limit is specified, the balance should work at the specified temperature condition; electronic The balance also has requirements for the humidity of the environment. For example, the relative humidity of the Class I balance requires no more than 80%.


The third is the horizontal state. Generally, high-precision electronic balances are equipped with a level adjustment device and a leveler. In use, the horizontal state of the balance should be checked frequently. In fact, some users often neglect to check the horizontal status of the balance (the electronic balance often causes squareness or unevenness due to movement or other reasons). This is also the main reason for the inaccuracy of the balance data.


The fourth is calibration at any time. Some people believe that the electronic balance is accurate within the validity period after the periodic verification, and the importance of calibration is often ignored or even not calibrated. As everyone knows, due to changes in environmental conditions, man-made factors and other factors, the measurement performance of electronic balances often changes slightly, which requires us to calibrate them in daily use. So how do we calibrate? The electronic balance should be calibrated daily or before each use, and the frequency of calibration can be increased if necessary. The weight for calibration is theoretically the higher the level, the better. Generally, the weight error should be no more than 1/3 of the allowable error of the balance, and it should be sent to the quality supervision department for regular inspection. If the error is found to exceed the standard, Send it to the quality supervision department for testing in time to avoid loss.
