Hold the new tube vertically and gently tap it to cause any internal debris to collect at one end.
Internal debris can cause spurious counting.
3 Slide the tube into the exposed hole in the instrument rear plate. Rotate the tube as needed until it
seats in the front connector. Twist the tube slightly until it snaps into place. You may need to twist
in either direction, depending on the tube's initial position in the front connector.
4 Mount the rear connector housing over the exposed tube end.
5
Gently twist the connector while holding the tube at the back edge of the upper belt. The rotation
should be about 1/4 turn.
