2.3 Approvals
Copies of the name plate and the declaration of conformity are
provided in the enclosed supplementary documentation (order no.
90 33 890).
Do not stick anything on the name plate on the gas detector. The
technical suitability tests are valid for the X-am 2500 gas detection
instrument and the calibration cradle. The explosion-protection
approvals are only valid for the X-am 2500 gas detection instrument;
the calibration cradle must not be used in the Ex zone.
The BVS 10 ATEX E 080 X technical suitability test is based on the
adjustment with the target gas.
3 Configuration
To individually configure an instrument with standard configuration,
the instrument must be connected to a PC via the USB infrared cable
(order no. 83 17 409). The configuration work is carried out using the
PC software Dräger CC - Vision. The PC software Dräger CC Vision
can be downloaded from the following web address free of charge:
www.draeger.com/software.

Standard instrument configuration:
WARNING
CSA requirement: Measured values over the full scale value
may indicate an explosive atmosphere.
Only applies for class II certification. CSA standard C22.2 no.
152 does not contain any requirements for class II hazard
areas. Therefore this device was not tested for class II by the
CSA. The sensor may become blocked and not measure the
gas correctly or not warn the user that gas measurement is
not possible.
WARNING
CSA requirement: The sensitivity must be tested every day
before first use using a known concentration of the gas being
measured corresponding to 25 to 50 % of the full concentration
value. The accuracy must be 0 to +20 % of the daily value. The
accuracy may be corrected via calibration.
NOTICE
CSA requirement: Only the combustible gas detection portion
of this instrument has been assessed for performance.
The instrument has not been classified by the CSA for use in
mines.
