1. The balance should be preheated for about 2-3 hours
2. Because the balance should be horizontal, if it is not to be adjusted
3. When the weighing plate of the balance is not weighed, it should be displayed at zero position stably
4. Press the "CAL" key to start the internal calibration function of the balance, and then electronically. Explain that the electronic balance should have been calibrated
If there is an error in the calibration, the electronic balance display will display "Err" for a short time, so it should be reset and calibrated again. Second, external calibration
1. The balance should be preheated for more than 3 minutes
2. The balance should be in a horizontal state
3. The balance plate should be stably displayed as zero when there are no weighed items
4. Press the "CAL" key. Start the calibration function of the balance
5. Display the weight value of the external calibration weight on the display of the balance
6. Put the standard weight meeting the accuracy requirements on the weighing plate of the balance
7. When the display value of the electronic balance remains unchanged, it means that the external calibration work has been completed, and the standard weight can be taken out
8. The zero position of the balance is in standby state
If there is an error in the calibration, the electronic balance display.
2. External calibration
1. The balance should be warmed up for more than 3 minutes
2. The balance should be in a horizontal state
3. When the weighing plate of the balance is not weighed, it should be stably displayed as zero
4. Press the "CAL" key. Start the calibration function of the balance
5. Display the weight value of the external calibration weight on the display of the balance
6. Put the standard weight meeting the accuracy requirements on the weighing plate of the balance
7. When the display value of the electronic balance remains unchanged, it means that the external calibration work has been completed, and the standard weight can be taken out
8. The zero position of the balance is in standby state
If there is an error in the calibration, the electronic balance display.
