NOTICE
The mobile app does not have to be closed or exited after operating the gas
detector. In case of an error, exiting and restarting the mobile app may be
helpful. If the mobile app icon has accidentally been deleted on the home
screen, this can be restored.

Connecting the sensor unit and control unit

Requirements:
– Sensor unit is turned on.
– Control unit is turned on.
– Mobile app is open.
Connecting the units:
1. Select Connect ( ) in the center of the Measure or Calibrate view.
 The dialogue with the connection set-up appears.
 The units are paired in just a few seconds.
 Once the sensor unit is connected, the status LED is permanently lit and
the Measure view is displayed.
Connection to another sensor unit
The connection process starts with an attempt to connect the control unit to the
most recently connected sensor unit. If the intention is to connect to a different
sensor unit, click on Other in the connection set-up dialog. Activated sensor
units which have not been connected are displayed with their serial numbers.
Select the sensor unit to be connected in order to start a new connection
process.
Repeated connection attempts
In some cases, it may take a while to establish a stable connection between the
control unit and the sensor unit. If the connection speed is too slow, the
connection is disconnected and a new connection attempt starts automatically.
A stable connection is generally established within between a few seconds and
one minute. If this is not the case, the pairing should be deleted on both units
and re-established (see technical manual). A corresponding notice appears on
the user interface. If this process does not result in any improvement, contact
Dräger Service.

Preparations for operation

WARNING
Risk of explosion!
When using an unsuitable control unit, carrying strap, or accessory, there is a
risk that flammable or explosive atmospheres could be ignited.
► The control unit on which the mobile app is installed must be suitable and
approved for use in explosion-hazard areas.
► Only use control units that are specified in the technical manual
(www.draeger.com/ifu).
► Only use the carrying strap supplied (order no. 6851846), which is made
from anti-static material.
► Only use accessories that are suitable for use in explosion-hazard areas.
Before first use, make sure that the sensor unit and control unit with installed
mobile app are available.
The functional integrity must be checked daily after the operational readiness
("every day of use") and before first use with a known concentration of the gas
to be measured close to the application-specific target concentration, or
preferably by way of a functional test with surrogate gas (For further
information, see the following chapter: "Running a functional test", page 12).
