Fig.24: Selection of another mass position
Below the selected mass is the information whether it is the preferred mass or not.
The molecular mass of the gas and the height of the peak relative to the largest peak
is also shown for this gas. The standard factor is a measure for the sensitivity of the
device to 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.
Calibration method The line shows whether calibration was external or internal.
6.4.2 Calibrate
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 105amu because the Ecotec E3000 converts
the calibration result for the measurement of these gases.
You get the most accurate calibration with the external calibrated leaks. 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
also required after the following actions:
• 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
