Electronic precision balance is an electronic balance in the high precision electronic balance,built-in high-precision weighing sensor,so its accuracy and sensitivity have been improved,is widely used in laboratories,research institutes and other places of quantitative analysis.We all know that electronic precision balance is the use of electromagnetic force balance principle to achieve weighing,although the measurement accuracy and sensitivity are more than the traditional mechanical precision balance,but because of this balance vulnerable to external temperature,electromagnetic environment and so on,so we use It is necessary to pay attention to some details,so that we can improve its weighing accuracy.

Precise balance use precautions:

1,fully preheated before use,generally should be more than 30 minutes,the higher the accuracy of the balance,preheat time should be extended accordingly.

2,before using the standard weight calibration,the accuracy of different scales used in the corresponding level of weight.In this case,

3,should be fixed after the time of reading load,such as 5 seconds after the show to load or read the unit are displayed when the value read.In this case,

4,multiple measurements,whichever is the average(3 to 5 times).

5,the room should avoid direct sunlight,the best choice for shade room or shading approach.

6,precision balance should be far away from the source,such as railways,highways,vibrators and other vibration machinery,can not be avoided when the shock measures taken.In this case,

7,should be away from heat and high-intensity electromagnetic fields and other environments.

8,the working room temperature should be constant to 20 or so is better.

9,the relative humidity in the working room should be between 45%to 75%is better.

10,the work room should be clean and avoid the impact of airflow.

11,before use to adjust the level bubble to the middle position.
