Use electronic balance tips

First, the electronic balance of the heart-gravity electromagnetic sensor reed (usually a total of 618) thin and thin, easily damaged, and the higher the precision of the balance, the gravity sensing reed is thinner, so in use Should pay special attention to protection, do not load onto the balance of objects weighing more than the scope of the weighing range, must not press the scale or hand the balance to the ground, so as not to damage the balance or change the performance of the gravity sensor, in addition to weighing an object For temples and other heavier objects, it is generally not to exceed 30 seconds. The weighing pan and its trays should be removed when moving and transporting.

2. The electronic balance is actually an instrument that measures the gravitational force of the earth on an object that is open on the weighing plate. Due to the difference in the latitude of the Earth's path, the gravitational acceleration (9-9.8 m2/s) is not the same everywhere. The accuracy of the weighing in the local area depends on whether or not correct corrections have been made and the accuracy of the correction of the forks. If you find that the scales that have been calibrated in Guangzhou have a certain error in the local area, this does not mean that there is any malfunction in the balance. The methods described in each model's electronic balance manual can be accurately weighed by correcting them using standard anvil codes approved by the metrology department.

Third, the electronic balance calibration agencies generally divided into three categories:

Fully automatic calibration: within the standard anvil and servo motor, only one function key can be used to complete the calibration in dozens of seconds. Generally, the electronic day average over the new type of one thousand one-gram accuracy is a fully automatic calibration mechanism. ;

Semi-automatic correction: built-in standard fork but no servo mechanism, after entering the calibration program, you need to manually load and remove the calibration code;

Manual calibration: There is no standard fork and servo in the balance need to manually enter the calibration program and add the standard anvil code to correct. The balance of low precision is manually corrected. 4. The electronic balance is a highly sensitive electronic measuring instrument that is highly sensitive to the environment. When using, care should be taken to install the table should be no obvious vibration, do not open in the air conditioning port, if these conditions can not be met, should take some improvement measures such as changing the location to install windproof ink, etc. At the same time pay attention to adjust the bottom angle screw level indicator The bubble centered. The lack of adjustment of the balance is one of the reasons for weighing errors.
