Leading to acquired test data, there are regular hour errors.Therefore increased newly again on the basis of original voltage calibration the time this
One calibration item, primarily directed to the calibration of system clock, but time calibration is in the manual calibration stage.
Legacy data acquires equipment calibration method disadvantage:
1) existing calibration method is in semi-automatic semi-manual state, is not carried out complete auto-calibration, however it remains
The drawback come of manual calibration tape.
2) cause data acquisition equipment overall calibration method to be dispersed with manual calibration method and depositing due to calibrating automatically, not at
System.
3) the calibration result format disunity that self calibration generates.
4) partial collimation result still needs to manually compute.
5) Calibration Report and calibration certificate still need to manually participate in establishment.
6) poor operability is calibrated, calibration progress is slow.
