FIGURE 13 Enclosure Rotation Considerations
Display Orientation
As supplied the display is oriented for viewing with the transmitter installed vertically, as shown in Figure
14. When the transmitter is installed in another orientation, perform the following steps to reorient the
display for ease of reading.
1.
Turn off power to the transmitter.
2.
Remove the enclosure cap that has the sightglass by rotating the cap counterclockwise.
3.
Fasten an anti-static wrist strap on your wrist and ground it to the transmitter ground screw.
4.
Use a Phillips blade screwdriver to remove the two screws holding the display; see Figure 14. The
display is electrically connected to the transmitter electronics by the display cable.
5.
Hold the display just in front of the transmitter enclosure. Rotate the display in quarter turn
increments to find the viewing position where reading is easiest. Four positions, 90° apart, are
provided. Do not rotate the display more than 180° in a clockwise or counterclockwise direction.
6.
Align the two holes in the display circuit board with the hex standoffs in the enclosure and install the
two screws removed above.
7.
Install the enclosure cap and remove the anti-static wrist strap.
