NOTE:

If you have a dual input analyzer, you can reapply power at this point. The initial reading from the other sensor will be momentarily zero. After about 60 seconds the reading will reach its final value.

3.Using a small Phillips screwdriver, remove the two screws holding the top flange of the sensor to the body.

4.Using a slight back and forth twisting motion carefully pull the flange from the sensor body. You are pulling against a single O-ring seal. Don’t pull too hard.

5.Using your thumb and forefinger, remove the lamp/LED circuit board from the sensor.

6.Insert the replacement board in the sensor and push the socket on the replacement board into the mating pins in the sensor.

7.Place the desiccant package in the sensor body.

8.Orient the flange so that the screw holes line up with the holes in the sensor body. Push the flange back on the sensor body and replace the screws. Don’t let wires push on lamp board. It may be necessary to turn the flange a small amount until the holes line up.

9.Place the sensor in the calibration cup and reconnect the cable.

10.Calibrate the sensor using either slope or standard calibration (Section 6.2 or 6.3). Do not use grab calibration. Failure to calibrate the sensor may reduce the life of the sensor. See Sections 8.2.5 and 8.2.6.
