2. Screw the 10 - 24 x 1/4" screws into the index mounting posts two turns. Do not tighten the screws.
3. Align the index wriggler (1) with the endpoint drive post (2). Carefully slide the index onto the mounting
screws. Verify the 100G Datalogging gas endpoint's housing drive post makes positive engagement with
the index wriggler. Hold the index in place and tighten the index mounting screws. Install and tighten the
mounting screws evenly.
Caution Indexes have varying drive mechanism styles. Failure to align the endpoint wriggler
with the index drive post can cause binding and lead to poor registration or meter failure. To
verify proper engagement of the index to the endpoint housing, spin the wriggler one
clockwise rotation, then one-counterclockwise rotation. Do not spin more than one complete
rotation. The wriggler should spin freely, with little or no resistance.
4. Slide the endpoint cover over the index and housing. The endpoint label should be clearly visible and
easily read.
