2. Align the appropriate mounting holes in the Transmitter with the holes in the bracket. Use the
bolts and washers provided to secure the Transmitter to the bracket.
Transmitter Type

3. Loosen the set screw on the outside neck of the Transmitter one (1) full turn.
4. Rotate the Electronics housing a maximum of 180° left or right from the center to the position
you require and tighten the set screw 13 to 15 lb-in (1.46 to 1.68 Newton meters), using a
4mm metric hex key wrench. See the following example and

4.4 Leveling transmitters with small absolute or differential
pressure spans
Mounting position of these transmitters is critical due to the smaller transmitter spans.
To minimize these positional effects on calibration (zero shift), take the appropriate mounting
precautions that follow for the given transmitter model.
See Figure 7 for suggestions on how to level the transmitter using a spirit balance.
To perform a Zero Trim after leveling, refer Table 16 for DAC trim.
For a model SMA810 or SMA845 transmitters, you must ensure that the transmitter is vertical
when mounting it. You do this by leveling the transmitter side-to-side and front-to-back. Mount
transmitter vertically to assure best accuracy. Position a spirit balance on pressure connection
surface of AP body.
