Fig. 24: Selection of another mass position
Below the selected mass is the information whether it is the preferred mass or not. In
addition, the molecular mass of the gas as well as the height of the peak in relation to the
highest peak for this gas are displayed. The standard factor is a measure of the sensitivity
of the device for the gas at the set mass position.
Cal. factor The calibration factor is displayed in this line.
Last cal. Based on this line, you can check when the last calibration took place.
Cal. method The line shows whether calibration was external or internal.
6.4.2 Calibration
The Ecotec E3000 can be calibrated most conveniently by adding an ECO-Check calibrated
leak. The ECO-Check can be integrated in the front panel of the device or set up at the
testing position. It compensates temperature fluctuation and thus enables the accuracy
required for calibration.
The ECO-Check calibrated leak includes R134a. It can be used for the calibration of gases
with a mass position from 40 to 105 amu because the Ecotec E3000 converts the
calibration result for the measurement of these gases.
You get the most accurate calibration with the external calibrated leak. The calibrated
leaks are valid for one gas each and temperature-insensitive.
When to calibrate? The device should be calibrated daily and after every operator change. Calibration is
additionally required after the following events:
 Sniffer line replacement
 Sniffer line probe replacement
 Switch between gases (if you calibrate with an external calibrated leak)
 Filter replacement
 Prompt for calibration by the system
