If the calibration is stopped when the instrument is writing the new
Flash, you may lose all the calibration
Chapter 1 Calibration Notices
Calibration Interval
Regular calibration can ensure the performance specifications of DG4000. You are
recommended to calibrate the instrument at a one-year calibration interval. You can
choose a proper calibration interval according to your requirement of the
performance ac cur acy but the calibration interval can not exceed 2 years (otherwise,
the specifications can not be guaranteed).
You are recommended to perform complete calibration at the calibration interval to
ensure that the instrument will remain within specifications for the next calibration.
Calibration Safety
T o perf orm calib ration, y ou need to input the correct password. The password is used
to prevent accidental or unauthorized calibr at ion of the instrument.
Press Utility Test/Cal Secure Code, input the correct password
using the knob and direction keys, press Secure and the calibration safety
protection turns off. Press CaliSelf to enter the calibration interface. Press Preset to
restore the calibration values to their default values.
The calibration password is “2010”. The password is stored in the non-volatile
memory and will not change at power-off or remot e interface res e t .
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 yo u do not need t o calibrate the items already calibrated again in the
next calibration.
CAUTION
calibration constants into the
constants and you need to perform the calibration again.
