1) The Technical Handbook and Instructions for Use / data sheets for the utilized sensors and the Dräger PC software CC Vision for Dräger X-am 5000 can be downloaded on the product page

of the X-am 5000 at the following Internet site: www.draeger.com See also the instructions for use provided and the data sheets for the sensors used.

2) For decreasing concentrations, the adjustment time for nonane is about 50 seconds.

3) Alcanes of methane to nonane, LEL values in accordance with EN 60079-20-1. At flow speeds of 0 to 6 m/s, the deviation of the reading is 5 to 10 % of the measured value. For an adjustment

to propane, the deviation of the display in the range of 80 to 120 kPa can be up to 6 %LEL.

4) certified measuring range for: 1 to 100 ppm

5) certified measuring range for: 0.4 to 100 ppm

6) certified measuring range for: 3 to 500 ppm

7) Range of measured values of a flammable gas that according to the standard can be around zero in a range of +/- 5 % LEL and where the instrument displays "0".

Range of measured values of oxygen that according to the standard can be around 20.9 % in a range of +/- 0.5 % LEL and where the instrument displays "20,9".

Range of measured values of a toxic gas that according to the standard can be in a range around 0 depending on the sensor and where the instrument displays "0". The exact values are

specified in the "Capture range" column for the relevant sensor.

This range of measured values is known as the "capture range" where minor measured value fluctuations (e.g. signal noise, concentration fluctuations) does not result in a changing display.

Measured values outside the capture range are displayed using their daily measured values. The set capture range can be exported using Dräger CC Vision and may be lower than

given above. The capture range is continuously activated in measuring mode and disabled in calibration mode

8) The instrument responds to most combustible gases and vapours. The sensitivities differ depending on the type of gas. We recommend a calibration using the target gas to be measured.

For the range of alkanes, the sensitivity decreases from methane to nonane.

9) A table of the cross sensitivities is contained in the Instructions for Use or the data sheet of the respective sensor.

10) The measuring signals can be negatively affected ethane, ethene, ethine, carbon dioxide and hydrogen. No O

11) The measuring signals can be affected additively by sulphur dioxide, nitrogen dioxide and hydrogen and negatively by chlorine.

12) The measuring signals can be affected additively by acetylene, hydrogen and nitrogen monoxide.
