Sensor Specifications And Instrument Settings For Other Gases - Dräger Pac 7000 Instrucciones De Uso

Footnotes:
1) For O A1 is the lower alarm threshold, used to indicate Oxygen
2
deficiency.
2) Please be aware of special settings by customer requirements.
3) Please be aware of limited lifetime of sensors. Excessive storage
reduces operating time of sensors.
o
Temperature range of storage is 0 ... 35 C (32 ... 95
4) Multiply cross sensitivity factor by gas concentration to get reading.
5) Range of measured values of oxygen which may be within a range of
20.9 % +/-0.5 % according to the standard and in which the measuring
instrument displays "20.9". Range of measured values of a toxic gas
which may be around zero according to the standard, within a range
depending on the sensor, and in which the measuring instrument
displays "0". The exact values are specified in the "Capture range"
column of the respective sensor.
This range of measured values is referred to as the "capture range", in
which slight variations of the measured value (e.g. signal noise,
fluctuations in concentration) will not result in a change of the displayed
value. If measured values are outside the capture range, the exact
measured values will be displayed. The set capture range can be read
with the Dräger CC-Vision Basic and may be smaller than specified
above. In measuring mode, the capture range is permanently activated;
in calibration mode, it is deactivated.
6) A table of the cross-sensitivities is included in the instructions for use or
the data sheet of the respective sensor.
7) The measured signals can be affected additively by acetylene, hydrogen
and nitrogen monoxide.
8) The measured signals can be affected additively by sulphur dioxide,
nitrogen dioxide and hydrogen and negatively by chlorine.
9) The measured signals can be affected negatively by ethane, ethene,
ethyne, carbon dioxide and hydrogen. No O measurement in helium.
