1. Activate automatic measuring range switchover with the
Dräger CC-Vision PC software.
2. Where applicable, select the "No measured values in
Vol% range" feature with the Dräger CC-Vision PC
software.
4.11 Usage time for X-am 2600
The usage time for the X-am 2600 is initially three years, with
the option of extending this with a licence as often as
possible. The free CC-Vision PC software is used to extend
the usage time. The licence can be ordered with the order
no. 3736525. The online assistance provided with the PC
software contains information about the licence.
During the start phase of the gas detection instrument, the
remaining usage time is shown in days. Here, only values less
than 999 days will be shown. Higher values are shown in the
display as ">999 d". This information is also shown in the
device information.
In the last 30 days of the usage time, an additional warning
(Code 151) will be shown in the display.

1) The recommended calibration interval can be extended to 12 months
if it is ensured that an advanced bump test (tolerance: max. ±20 %) is
carried out and passed before use in safety-relevant measurements.
The advanced bump test checks the existing sensitivity.
2) If the gas detector is used with the PID HC neo sensor in the X-
zone 5500/5800, a bump test must be carried out after no more than
7 days. This applies in particular if the X-zone 5500/5800 is continu-
ously powered by the Ex power supply. A bump test must always be
carried out when using the gas detector in the X-zone if the location of
the X-zone changes.
3) Alternatively, a calibration interval of 6 months may be implemented.
This requires the use of the X-dock maintenance station to conduct a
reading test of the type 'Extended bump test' every working day with a
tolerance of 10 % based on the target concentration. If the gas detec-
tor fails this test, it must be calibrated.
National regulations may stipulate shorter intervals and
must be applied.
CAUTION
Danger to health
Electrochemical sensors contain corrosive liquids.
► In the event of leaking, avoid contact with the skin and
eyes. In case of contact, rinse thoroughly with plenty of
water.
For changing, retrofitting or removing a sensor, refer to the
technical manual.

5.3
Test gases
Test gas properties (e.g. relative humidity, concentration) can
®
&
be found in the relevant sensor data sheet.
The relative humidity of the test gas is not relevant for O
sensors.
Different test gases are used depending on the type of
calibration.
5.4
Performing the bump test
The bump test can be performed as follows:
– Manual bump test
– Bump test with the bump test station
– Bump test with X-dock

Maintenance
Calibration interval
Depending on the conditions
of use, daily calibration may
be necessary. The interval
may be extended in incre-
3)
ments to up to 30 days
if no
deviations occur during cali-
bration in successive tests.
See the special data sheets
for the respective sensors.
