Replacing the Sensor

Caution!
Before handling the PC board, ensure you are properly grounded,
otherwise, static charges from your body could damage the electronics.
Such damage is not covered by the warranty. Grounding straps and kits
are available from electronics suppliers.
(1) Remove the four screws securing the case halves together.
(2) Carefully remove the front cover to expose the sensor (located near the top
of the instrument, near the alarm lights " Fig. 9).
(3) Remove the sensor from its sockets.
Caution!
The new replacement sensor must be the same part number and type as
the one being replaced; otherwise, improper operation will result.
(4) Install the new sensor in the sockets on the PC board (it can only be
installed one way). Fully seat the sensor against the board.
(5) Replace the front cover, making sure the sensor, horn gasket, and sensor
gasket are properly seated.
(6) 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.
Caution!
Do not over-tighten the screws; otherwise, the case may be damaged.
(7) Replace the four screws.
Warning!
Calibration is required after a sensor is installed; otherwise, the instrument
will not perform as expected and persons relying on this product for their
safety could sustain serious personal injury or death.
(8) The instrument MUST be calibrated as previously described.
