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

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.
