Safety-related informationen
1 Safety-related information
1.1 Basic safety information
Before using this product, carefully read the associated
instructions for use. This document does not replace the
instructions for use.
Incorrect calibration
An incorrect calibration leads to incorrect measured values.
► The sensitivity must be checked daily before first using the
device, with a known concentration of the gas to be
measured that corresponds to 25 to 50 % of the final
concentration. The accuracy must amount to 0 to +20 % of
the actual value. The accuracy can be corrected by
calibration.
1.2 Safety information on explosion
protection
Devices or components that are used in potentially explosive
atmospheres and which are tested and approved in
accordance with national, European or international explosion
protection guidelines may only be used under the approved
conditions in compliance with the statutory provisions.
Oxygen-enriched atmospheres
Explosion protection is not guaranteed in oxygen-enriched
atmospheres (>21 Vol% O
2
).
► Remove the device from the potentially explosive
atmosphere.
Risk of explosion!
► Do not open the gas detector in explosion-hazard areas.
Specific application conditions
In certain extreme conditions, open plastic parts and non-
earthed metal parts of the housing may store a combustible
level of electrostatic charge.
Activities such as carrying the device in a bag or attached
to a belt, operating the button field or cleaning the device
with a damp cloth do not represent a significant
electrostatic danger. However, if a mechanism which
generates static charge, such as repeated rubbing against
clothing, is identified, suitable precautionary measures
must be implemented, e.g. the use of anti-static clothing
and anti-static footwear.

4.2 Before entering the workplace
WARNING
Serious damage to health!
An incorrect calibration can lead to incorrect measurement
results, which may result in serious damage to health.
► Before performing safety measurements, check the
calibration by way of a bump test, adjust as necessary,
and check all alarm elements. If national regulations exist,
the bump test must be performed in accordance with
these regulations.
WARNING
Incorrect measurement results!
The gas inlet opening is fitted with a filter that protects against
dust and water. Contamination may change the qualities of the
dust and water filter.
► Do not damage the filter. Immediately replace damaged or
blocked filters.
To ensure correct function:
Do no cover the gas inlet opening.
Place the gas detector on clothing near the mouth.
At temperatures below -20 °C, there may be deviations of
>10 % of the measured value if the corresponding sensor
was calibrated at room temperature. Dräger recommends
calibration at the primary application temperature if
measurements will be taken at very low temperatures. This
enables the highest possible measurement accuracy.
After the gas detector has been switched on, the current
measured value is shown in the display.
Check whether the warning [!] appears. If it is displayed, we
recommend performing a bump test, see Section 4.2.3 on
Page 6.
