3.5.3 External calibration
For external calibration it is recommended to use leak rates > 2 g/a (0.07 oz/yr) when
calibrating the Ecotec E3000.
Notice: If significantly increased backgrounds are prevalent in your production
environment, larger leak rates for the calibration leak may be required.
Notice: If a calibration is started during the first 20 minutes after power on, a
warning will be issued. Only confirm and continue with the calibration if the
real warm-up has been longer (e.g. after a quick restart of the Ecotec
E3000)
The external calibration is a semi-automatic process during which the user will have
to follow some instructions. The calibration process may be started via the “
CAL” -
button from the measuring mode at any time (except when the menu is open or the
function has been locked). A running calibration process may be cancelled by
operating the “
ESC” button.
After pressing the CAL button the currently selected gases with their selected mass
positions will be listed. By pressing one of the four buttons on the right side of the
display, the gas to be calibrated externally will be selected. Only gases that are
currently enabled will be available for calibration.
Notice: If more than one gas is currently selected for measurement, a calibration
will be required for each gas separately.
Please check whether the leak rate and the gas type displayed equals the leak rate
and the gas type of the external leak you plan to use. If the leak rate is different press
“
EDIT LEAK RATE” and enter the correct leak rate value. Press “START” afterwards to
begin with the calibration process.
