- IR Butane 25 % Vol - 2% Vol Butane Cal Check gas
- IR Propane 100 % Vol - 8% Propane Cal Check gas
- IR Methane 100 % Vol - 20% Methane Cal Check gas.
(1) While the device is turned ON in a clean, fresh air environment, verify that
readings indicate no gas is present.
(2) From the normal measure screen press the button to display
“BUMP TEST?”.
(3) Verify the gas concentrations displayed match the Calibration Check Gas Cyl-
inder. If they do not, adjust the values through the Calibration Setup menu.
Depending on the sensors installed, there could be one to five separate
Bump Tests performed, each with a different cylinder, regulator, and tubing
used.
(4) Attach the demand regulator [supplied in the calibration kit] to the cylinder pro-
viding the indicated gases.
(5) Connect tubing [supplied in the calibration kit] to the regulator.
(6) Attach the other end of tubing to the device pump inlet.
(7) Press the ON/OFF button to start the bump test:
the progress bar advances
the sensors respond to the gas.
The message BUMP TEST PASS indicates a successful Bump Test of the sensors.
If any sensor fails the Bump Test:
- the message BUMP TEST FAIL appears
- the failed sensor is indicated.
If there are more sensors to be Bump Tested, the next sensor displays and the
process repeats from Step 4.
If there are no more sensors to be Bump Tested, the tubing can be removed from
the device pump inlet.
In the ALTAIR 5X IR, Bump Testing of a combustible IR sensor causes the catalytic
combustible sensor to enter the LockAlarm condition. While an device with a % Vol
methane IR sensor automatically recovers from LockAlarm, % Vol propane or bu-
tane devices do not. For these devices, clear the LockAlarm state by turning the de-
vice off, then on while in a fresh air environment. See chapter 2.8 for additional
details.
