During Operation; Identifying Alarms - Dräger X-am 5600 Instrucciones De Uso

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:
» «
(measuring range exceeded) or
» «
(measuring range not reached).
– After the measuring range of the TOX measuring channels has been
exceeded temporarily (up to one hour), checking the measuring channels
is not necessary.
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
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.

Identifying alarms

An alarm is displayed visually, audibly and through vibration in a specific pattern.
At low temperatures the legibility of the display can be improved by switching
on the backlight.
