Electronic balance

How to calibrate before use? Electronic balances must be calibrated for long periods of time, otherwise measurement errors will be large, so it is important to have the correct calibration method.

Electronic balance

The calibration methods mainly include internal comparison and external school.

Electronic balance

Internal school:

1, the balance should be warmed up, the time is about 2-3 hours

2, the balance should be horizontal, if not to adjust

3. When the balance is weighing the weighing object, it should be displayed as zero.

4. Press the “CAL” button to start the calibration of the balance. The electronic balance will display “C” later, indicating that the internal calibration is in progress.

5. When the electronic balance display shows zero position, the electronic balance should be calibrated.

If an error occurs during the calibration, the electronic balance display will display “Err” for a short time and should be re-zeroed and recalibrated.

Electronic balance

Foreign school:

1, the balance should be warmed up for more than 30 minutes

2. The balance should be in a horizontal state

3. When the balance is weighing the weighing object, it should be displayed as zero.

4. Press the “CAL” button to start the calibration function of the balance.

5. The weight value of the external correction weight is displayed on the display of the balance.

6. Place the standard weight that meets the accuracy requirements on the scale of the balance.

7. When the display value of the electronic balance is unchanged, it indicates that the external calibration work has been completed, and the standard weight can be taken out.

8. The balance shows that the zero position is inactive.

If an error occurs during the calibration, the electronic balance display will display “Err” for a short time and should be re-zeroed and recalibrated.
