Standby Delay
The Protec P3000 offers a STANDBY mode to preserve filters and sensor life time in
times when the Protec P3000 is not used. During the STANDBY mode the flow through
the sniffer line will be stopped, thus no dirt is pumped through the filters and the
sensor is not subjected to the helium background presented in the testing
environment.
The time until the Protec P3000 goes into STANDBY mode is determined by the
STANDBY DELAY time. The STANDBY delay time can be set to values between 10 s and
1 h. If the probe is not moved for the set STANDBY delay time the Protec P3000 will
switch to STANDBY mode automatically. If the probe is moved during this time, the
counter will be set back to zero and start again.
If the probe is picked up when the Protec P3000 is already in STANDBY mode the
Protec P3000 will go back into operation automatically and will be ready for
measurement again in approx. 5 sec.
Default value: 10 min.
Notice It is recommended to keep the STANDBY delay time as short as possible to
minimize wear of the systems without causing too much interruption of your
operations.
Cal
In the CALibration submenu an internal calibration can be ENABLED or DISABLED . If the
function is set to DISABLED , only a proof function with the built-in PRO-Check
reference leak will be possible.
Default value: ENABLED
Change menu PIN
Any changes to the current settings may be password protected. The menu PIN can
be changed in the “change menu PIN” submenu.
If a new PIN is entered the Protec P3000 software will ask to repeat the new PIN to
prevent entering errors. Afterwards the menu PIN will be changed to the new value.
