Druck DPI 142/150 Calibration Manual

K382 Issue No. 1
Introduction
At manufacture this instrument is calibrated against precision calibration
equipment which is traceable to the U.K. National Physical Laboratory.
The DPI 142 and DPI 150 incorporate a calibration menu; for the indicator to
stay accurate, a calibration check should be carried out at chosen intervals (
the
recommended maximum interval is 12 months
). If the accuracy of the indicator
is not within the permissible deviation, carry out a calibration adjustment.
Using the
Set-up/Status/Calibration History
menu, the calibration status of
the indicator can be displayed on the front panel screen. The
Calibration
History
menu gives a list of dates of the stored calibration corrections.
