Check that the gas inlet opening on the instrument is not covered or dirty.
WARNING
Before any measurements relevant to safety are made, check the adjustment
with a bump test, adjust if necessary and check all alarm elements. If national
regulations apply, a bump test must be performed according to the national
regulations.
Faulty adjustment may result in incorrect measuring results, with possible
serious consequences.
NOTICE
If the gas detector is used for offshore applications, a distance of 5 m to a
compass must be complied with.
The instrument can be operated normally. If the warning message does
not disappear automatically during operation, the instrument must be
serviced after the end of use.
The instrument is not ready to measure and requires maintenance.
WARNING
Explosion hazard! To reduce the risk of ignition of a flammable or explosive
atmosphere, strictly adhere to the following warning statements:
In an oxygen enriched atmosphere (>21 vol.-% O
2
), the explosion
protection cannot be guaranteed; remove instrument from the explosion-
hazard area.
High off-scale readings may indicate an explosive concentration.
During operation
–
During operation, the measured values for every measured gas are displayed.
–
In the event of an alarm, the corresponding displays, including the visual,
audible and vibration alarms, are activated. See section "Identifying alarms".
–
If a measuring range is exceeded or not reached, the following displays are
shown instead of the measured value display:
–
After the measuring range of the TOX measuring channels has been
exceeded temporarily (up to one hour), checking the measuring channels
is not necessary.
Identifying alarms
An alarm is displayed visually, audibly and through vibration in a specific pattern.

NOTICE
Special states in which there is no measuring operation (quick menu,
calibration menu, warm-up of sensors, password input) are indicated by a
visual signal (slow flashing of the alarm LED
).
NOTICE
Fast temperature and humidity changes influence the measured signal. If
temperature and humidity jumps are anticipated, Dräger recommends using a
humidity pre-tube for the measurement.
WARNING
If an IR sensor is used in the Dräger X-am 5600, a calibration of zero point and
sensitivity must be carried out after experiencing an impact load that results in
a non-zero display when exposed to fresh air.
NOTICE
At low temperatures the legibility of the display can be improved by switching
on the backlight.
