Dräger X-am 2500 Portable Gas Monitor Flashcards
The Dräger X-am 2500 is a 4-in-1 gas detection device
The device accurately detects O2, LEL, CO, and H2S.
The Dräger X-am 2500 instrument requires a 5-minute sensor warm-up period before the device can be calibrated and/or the peaks cleared.
While warming up, symbol is displayed in the upper right of the display screen.

Calibrating the Dräger X-am 2500
Fresh air calibration of the Dräger X-am 2500 sets the Oxygen channel to 20.9% by volume and the sensors to zero. Ensure calibration occurs in an area of clean air.
How to calibrate
- Press the blue “+M” (Quick Menu) button three times
- Press “OKon” button to activate fresh air calibration
- Press “OKon” button
Bump Test
A Bump Test uses a small quantity of test gas over the instrument to warrant that it responds as it should trigger audible and visual alarms. A Bump Test is done at the beginning of every shift. All station X-Dock stations have two calibration bottles attached: one four gas blend with methane (daily bumps) and the other pentane (monthly calibrations). The Bump Test typically takes 60-90 seconds to complete and starts by inserting the Dräger X-am 2500 X Dock station.

Alarms
O2 Sensor- low level alarm (A1) 19.5% and high level alarm (A2) 23.5%
LEL Sensor- low level alarm (A1) 10% and high level alarm (A2) 20%
CO Sensor- low level alarm (A1) 25 ppm and high level alarm (A2) 50 ppm
H2S Sensor- low level alarm (A1) 10 ppm and high level alarm (A2) 15 ppm
A1 Alarm - Low Level Alarm
“A1” alarm sounds if the concentration amount is higher than normal, but does not constitute an acute hazard
A2 Alarm - High-Level Alarm
“A2” alarm signals danger of death – leave the danger zone IMMEDIATELY!
- Alarm CANNOT be acknowledged until air quality improves to the below the high alarm level
Over-Range Alarm
Indicates the ambient air contains concentrations exceeding the measuring range of the sensor used
- The over-range symbol alternates in the display with an “A2” Main Alarm symbol
* Leave the danger zone IMMEDIATELY!
* An “A2” alarm CANNOT be acknowledged
