3.5.1 Verifying a calibration (proof function)
Notice: The description of how to perform a verification applies to the use of the
ECO-Check reference leak for detecting helium or hydrogen (forming gas)
accordingly.
Notice: A verification can only be performed while the Ecotec E3000 is in
measurement mode (not when the main menu is opened or during start-
up).
If the sniffer tip is inserted into the opening of the ECO-Check reference leak a
verification of the calibration (proof function) will be started automatically.
While holding the sniffer tip in the test leak opening, the Ecotec E3000 will check the
reading from the ECO-Check. Afterwards the operator will be requested to remove
the sniffer tip from the leak opening.
Notice: Any time during the verification procedure an internal calibration may be
started by pressing either the right sniffer probe button or the CAL button
on the main display.
The results of the verification will be displayed in a summarizing screen.
For gases that are enabled for internal calibration either “Check ok” or “Recalibration
required” will be stated.
For gases that are disabled for internal calibration “Gas disabled” will be stated.
For gases that cannot be calibrated with the ECO-Check because of very high or
very low mass positions, “gas specific check impossible” will be listed.
For returning to the measuring mode, please press the right probe button or press
“
OK
” on the main display.
