Calibration and Self-Test
The Ecotec E3000 can be calibrated internally with the built-in ECO-Check reference
leak or externally with an external calibrated leak (Cat. No. 122 20 - 122 35).
The built-in ECO-Check reference leak can be used for a self-test of the Ecotec
E3000 as well as for calibration of gases that are measured at mass positions
between 40 and 105 amu. If a gas is measured on a mass position below 40 amu or
above 105 amu it will be permitted for internal calibration in the “
EDIT
GAS
” menu.
A ECO-Check reference leak (cat. no. 521-001) maybe connected to the Ecotec
E3000 remotely and be used for internal calibration and verification of the calibration
(proof function) for helium and hydrogen. Internal calibration and verification may be
performed accordingly.
Notice
Do not calibrate the Ecotec E3000 during the first 20 minutes after start-up.
Also a verification of the calibration may lead to wrong results in the first 20
minutes after start-up.
Only confirm and continue with the calibration or proof, if the real warm-up
time has been longer than 20 minutes (e.g. after a quick restart of the
Ecotec E3000)
Notice:
When detecting hydrogen a longer warm-up time is required. For hydrogen
please calibrate the Ecotec E3000 not before 1 h after start-up.
Notice:
The accuracy of an internal calibration is less than the accuracy of a
calibration with an external calibrated leak.
Notice:
The ECO-Check reference leak is a temperature compensated leak. It
must only be used when electrically connected to the main unit, either
when inserted into its port or when connected to the main unit via a Sub-C
extension cord. The leak rate printed onto the body of the ECO-Check is
only valid at 20°C (68F) and will vary greatly with temperature.
To compensate for this the ECO-Check reference leak is equipped with a
temperature sensor and a compensation curve is stored in the software
which automatically compensates the test leak rate for changes in
temperature when connected to the main unit.
A calibration or verification with the ECO-Check reference leak not being
connected to the main unit will cause a wrong calibration of the Ecotec
E3000 and / or will lead to wrong testing results.
