Operation of the Protec P3000
3.5.2 Internal calibration
Notice
A calibration can only be performed while the unit is in one of the two
measurement modes: standard operation mode or I•Guide operation
mode. A calibration will not be started if the main menu is opened.
If the sniffer tip is inserted into the opening of the PRO-Check reference leak with the
right probe button pressed while in measurement mode a calibration will be started
automatically. While holding the sniffer tip in the test leak opening, the Protec P3000
will measure the test leak. Afterwards the operator will be requested to remove the
sniffer tip from the leak opening.
After completion of the internal calibration a screen summarizing the results of the
calibration will be displayed. The old calibration factor as well as the new calibration
factor will be displayed. If warnings are active and have been acknowledged during
the calibration process, the message is endorsed with the information "with active
warnings".
To avoid unintended overwriting of a previous external (more accurate) calibration,
the operator needs to “Accept new values (anyway)?”.
