Chapter 1 Calibration Notices
Calibration Interval
Regular calibration can ensure the performance specifications of DG1000Z. You are
recommended to calibrate the instrument at a one-year calibration interval. You can
select a proper calibration interval according to your requirement of performance
accuracy. However, the calibration interval cannot exceed 2 years; otherwise, the
specifications cannot be guaranteed.
You are recommended to perform a complete calibration at the selected calibration
interval to ensure that the instrument will remain within specifications before the
next calibration.
Calibration Safety
You need to input the correct password before calibration each time you want to
calibrate the instrument. The password is used to prevent accidental or unauthorized
calibration of the instrument.
Press Utility Test/Cal Manual Cal, input the correct password using the
numeric keyboard. Then, press OK to enter the calibration interface.
The calibration password is “123456”. The password is stored in the non-volatile
memory and will not change at power-off or remote interface reset.
You are allowed to modify the calibration password. Press Utility Test Cal 
Password Modify, press Old, New and Confirm in turn, input the corresponding
password and then press OK to finish the password modification.
To Stop the Calibration
You can power off the instrument to stop the calibration at any time during the
calibration. The calibration data stored will not be cleared when the calibration is
stopped and you do not need to calibrate the items already calibrated again in the
next calibration.
CAUTION
If the calibration is stopped when the instrument is writing the new
calibration constants into the Flash, you may lose all the calibration
constants and you need to perform the calibration again.
