Replacing The Altair Pro Sensor (Except Remote O 2 Version); Caution; Warning - MSA ALTAIR Pro Manual De Operación

Replacing the ALTAIR Pro Sensor
(Except Remote O 2 Version)
1. Remove the four screws securing the case halves together after
the instrument is turned OFF (except Steel Mill version).
2. For Steel Mill version only, remove battery before proceeding with
sensor replacement.
3. Carefully remove the front cover to expose the sensor (located
near the top of the instrument, near the alarm lights).
4. Remove the sensor from its sockets.
5. Install the new sensor in the sockets on the PC board (it can only
be installed one way). If replacement sensor is equipped with a
"shorting" clip, it must be removed prior to installation in the
instrument. Fully seat the sensor against the board.
6. Replace the front cover, making sure the sensor, horn gasket, and
sensor gasket are properly seated.
7. Ensure the interface and connectors for the display are clean and
free of dirt for proper operation.
• If necessary, the display connectors can be cleaned with a soft,
lint-free cloth.
8. Replace the four screws.
Do not over-tighten the screws; otherwise, the case may be
damaged.
9. The instrument MUST be calibrated as previously described. Allow
a minimum of 60 minutes after the new sensor is installed before
calibrating to ensure the new sensor reaches equilibrium.
The new replacement sensor must be the same part number
and type as the one being replaced; otherwise, improper oper-
ation will result.
Calibration is required after a sensor is installed; otherwise,
the instrument will not perform as expected and persons rely-
ing on this product for their safety could sustain serious
personal injury or death.
