Please hold the sniffer tip to the outlet of the external calibrated leak. Hold the sniffer
tip steady and very close to the opening, however, do not clog the opening with the
sniffer tip.
Some air also needs to enter the sniffer tip in addition to the refrigerant from the
external calibrated leak. If the leak rate signal indicated by the bar graph is stable
press “
OK
”.
Keep holding the sniffer tip steady in front of the opening while the Ecotec E3000
reads the leak rate of the calibrated leak. During this time the text “Please wait…” will
be displayed.
When the analysis of the calibrated leak signal is completed a message “sniff air!”
will be displayed.
Remove the sniffer tip from the opening of the calibrated leak and hold the sniffer tip
into the air, as far as possible from any sources of refrigerant. Wait until the bar graph
shows a stable signal again and press “
OK
” once more.
Notice: When calibrating for helium or Hydrogen, the air signal will decrease only
slowly and the time for the air signal to stabilize may be as long as 30 sec.
Please do not confirm the air signal too early, as this will lead to a wrongly
calibrated leak rate signal later.
A message “Please wait…” will be displayed until the calibration is finished. After
completion a menu page summarizing the old values as well as the new values will
come up. To activate the new calibration please “confirm to save new values”.
