Operation of the Protec P3000 37
The Protec P3000 may automatically go into standby after a preset time of inopera-
tion (see Chapter 4.4.1 for details on how to set-up this function) and operation will
automatically resume if the probe is picked up again.
The Protec P3000 can also be set into
STANDBY mode manually by pressing the
Standby button in the main menu.
To resume work you can move the sniffer tip or, alternatively, press the start button
in the main menu.
Operating in moist environment
For operation in an environment where moisture (e.g. condensating water) may
occur, a water-protection tip is available (Cat. no. 12246) which will protect the
Protec P3000 against intake of liquids if necessary. For details on how to install the
water potection tip see 1.6.2)
Protection mode and high helium background
The Protec P3000 is equipped with a protection mode against contamination with
huge amounts of helium. This contamination mode will help the leak detector to clean
up faster after detection of gross leaks.
If the Protec P3000 switches to
GROSS MODE the item „GROSS“ is displayed and an
acustic signal is to hear.
If a huge amount of helium is detected the Protec P3000 may show the message
HELIUM CONTAMINATED. The leak detector will come back to measurement mode auto-
matically after clean up and the displayed item „GROSS“ disappears.
Notice The Protec P3000 should not be switched off or set to
STANDBY mode while
HELIUM CONTAMINATED is displayed as this will trap the increased levels of
helium inside the sensor and it cannot be pumped away for clean up of the
Protec P3000. Switching off the Protec P3000 while contaminated with
large concentrations of helium will in fact lead to significantly increased
start-up times afterwards. If this has happened unintentionally, just switch
on the Protec P3000 and let it sit in "Warm up" until it reaches
measurement mode.
Notice In
HIGH FLOW mode leak rates in the range < 1x10
-5
mbar l/s are reduced
during a time of 30 Sec. to the current background value.
For details on how to set up the
CONTAMINATION LIMIT please refer to Section 4.4.1.
3.4.1 Standard Operation Mode
Provided the Protec P3000 has been set-up to meet the requirements of the partic-
ular application and it has been calibrated (see Section 3.5), a measurement is
performed as follows:
Do not suck in any liquids.
