2-4 How the Instrument Works
kina22e chapter 2.fm technical handbook(1206)
If no display unit is connected, error messages or warnings may be acknowledged
by pressing both buttons of the sniffer line simultaneously.
The external display unit also offers four 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)
2.3.2 Sniffer line with probe display
The probe handle also offers a small display for operating the Ecotec E3000 remotely
without access to the main unit during normal leak detection operation.
In addition to the display, the sniffer probe offers two press buttons. The left button
will function as the ZERO button in any operating mode. By pressing the left button
the current background reading is set to ZERO. The ZERO function can be disabled
by holding the ZERO button for 2 seconds. A beep will indicate that the ZERO
function has been successfully switched off. The ZERO function can be re-activated
by pressing the ZERO button once again. For details on the ZERO function see
section 4.5.1)
