Drager X-am 5000 Technical Manual page 7

Use only supply units ABT 0100 (83 22 237), HBT 0000 (83 18 704) or HBT 0100
(83 22 244). Check the supply unit for approved batteries and applicable temperature
class.
Note the following for CSA (Canadian Standards Association) applications:
For the CSA approval only the functions of the device component that is used to
measure flammable gases are tested. The device is not approved by CSA for use in
mining.
Before daily use, test the sensitivity with a known concentration of the applicable gas
corresponding to 25 to 50% of the maximum concentration. The accuracy must be
within a range of 0 to +20% of the actual value. Perform a calibration to correct the
accuracy if necessary.
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.
CSA requirement: Measured values over the full scale value are displayed as an ex-
plosive concentration.
CSA requirement: a measurement suitability test must be conducted for flammable
gases.
