Operation procedure of electronic balance
Operation procedure of electronic balance.
1. There should be a good environment for the use of electronic balance, and the experimental platform should be stable. Do not have strong electromagnetic equipment around the interference, first of all, check and adjust the balance to the horizontal position.
2. Check in advance whether the power supply voltage is matched (if necessary, configure voltage regulator), according to the requirements of the instrument power preheating to the required time. Usually half an hour.
3. Turn on the balance switch after enough warm-up time, the balance will automatically adjust the sensitivity and zero point. Then the balance is calibrated. The balance is divided into built-in and external calibration, the specific operation according to the manual shall prevail. After the stabilization mark is displayed, formal weighing can be carried out.
4. When weighing some specific items will be clean weighing bottle or weighing paper on the weighing plate (some do not need to be used, depending on the situation), close the side door, gently press the tare key, the balance will automatically calibrate the zero point, and then gradually add the substance to be weighed until the desired weight.
5. Weighing should be removed in time at the end of the weighing bottle (paper), close the side door, cut off the power supply, and do a good job of registering the use of the situation.
