Operation of the Protec P3000
When operating in I•Guide Mode, the info page will state information about the
currently selected program: the selected program name, the gas used for this
program, the number of points to be checked for this program, the selected
measuring and wait time as well as the global trigger.
3.5 Calibration and Self-Test
The Protec P3000 can be calibrated internally with the built-in PRO-Check reference
leak or externally with an external calibrated leak (Cat. No. 122 37 - 122 39).
Notice
If a calibration is started during the first 20 minutes after power on, a
warning will be issued.
Do not calibrate the Protec P3000 during the first 20 minutes after start-up.
Also a verification of the calibration may lead to wrong results in the first 20
minutes after start-up.
Only confirm and continue with the calibration if the real warm-up has been
longer than 20 min. (e.g. after a quick restart of the Protec P3000.)
The built-in PRO-Check reference leak can be used for a self-test of the Protec
P3000 as well as for internal calibration.
Notice
The PRO-Check reference leak is a temperature compensated leak. It
must only be used when electrically connected to the main unit, either
when inserted into its port or when connected to the main unit via a Sub-D
extension cord. The leak rate printed onto the body of the PRO-Check is
only valid at 20°C (68F) and will vary greatly with temperature and time.
To compensate for this the PRO-Check reference leak is equippend with a
temperature sensor and a compensation curve is stored in the software
which automatically compensates the test leak rate for changes in
temperature when connected to the main unit.
A calibration or verification with the PRO-Check reference leak not being
connected to the main unit will cause a wrong calibration of the Protec
P3000 and / or will lead to wrong testing results.
