Two methods to effectively calibrate the one-ten-thousandth balance? Professionals from Tianma Instrument Network said that they found in the verification that the error in the first measurement test of the balance was relatively large. No calibration has been performed during the interval and the balance is considered to show zero for direct weighing. (It should be pointed out that the zero point displayed when the balance is turned on for one ten-thousandth does not mean that the accuracy of the data weighed by the balance meets the test standards, but only that the stability of the zero position of the balance is qualified. Because it needs to be comprehensive Consider compliance with other specifications). Due to long storage time, location movement, environmental changes or to obtain accurate measurement, the balance should generally be calibrated before use. There are two types of calibration methods: internal calibration and external calibration.
First, one-ten-thousandth scale Internal calibration:
(1) The one-thousandth balance should be preheated, and the time is about 2-3 hours.
(2) The one-thousandth balance should be horizontal, if it is not, it must be adjusted.
(3) When there is no item to be weighed on the weighing pan of the one-thousandth balance, it should stably display zero.
(4) Press the "CAL" key to start the internal calibration function of the one-ten-thousandth balance, and the one-thousandth balance will display "C" later, indicating that the internal calibration is in progress.
(5) When the 1/10,000 balance display shows zero, it means that the 1/10,000 balance should have been calibrated. If there is an error in the calibration, the display of the ten-thousandth balance will display "Err", and the display time is very short, and it should be reset to zero and re-calibrated.
Second, one-ten-thousandth balance school:
(1) The one-thousandth balance should be preheated for more than 30 minutes.
(2) One ten-thousandth balance should be in a horizontal state.
(3) When there is no item to be weighed on the weighing pan of the one-thousandth balance, it should stably display zero.
(4) Press the "CAL" key to start the calibration function of the ten-thousandth balance.
(5) The weight value of the external calibration weight is displayed on the display of the one-thousandth balance.
(6) Put the standard weight that meets the accuracy requirements on the weighing pan of the one-ten-thousandth balance.
(7) When the displayed value of the one-thousandth balance remains unchanged, it means that the external calibration work has been completed and the standard weight can be taken out.
(8) One ten-thousandth balance shows that the zero position is in a standby state. If there is an error in the calibration, the display of the ten-thousandth balance will display "Err", and the display time is very short, and it should be reset to zero and re-calibrated.
