How the Protec P3000 Works
• The green LED will indicate that the Protec P3000 is in operation (switched on).
The green LED will show continuous green light if an external display unit is
connected and will blink if no external display unit is detected.
• The red LED will be blinking in case of an error message, continuous red light
indicates a warning.
If no display unit is connected, error messages or warnings may be acknowledged
by pressing both buttons of the SL3000 sniffer line simultaneously.
The external display unit offers four additional buttons:
• The START / STOP buttons have no function (the external display unit may also
be used with other INFICON leak detectors which need these buttons)
• The MENU button will open the software menu.
• The ZERO button will set the current background reading to zero. (For details on
the ZERO function see Section 4.4.1)

The probe handle also offers a small display for operating the Protec P3000 remotely
without access to the main unit during normal leak detection operation.
