To attach the 100G Datalogging gas endpoint to the meter
1. Align the endpoint (1) so one of its four drive slots lines up with the meter's drive dog (2).
2. Carefully place the 100G Datalogging gas endpoint on the meter.
Warning Failure to correctly align the meter drive post and endpoint drive slot can cause
binding and lead to poor registration or meter failure. If there is a gap between the endpoint
gasket and the meter, it may be the drive slot of the endpoint assembly's wriggler is not
correctly aligned with the meter drive slot. Remove the 100G Datalogging gas endpoint
assembly and repeat the alignment procedure. You must establish proper engagement of
the meter drive dog within the endpoint wriggler slot.
3. Install endpoint to meter mounting screws in an alternating fashion. Use the original mounting screws if
they were the correct size and not corroded. If the original screws were discarded, use the correct
replacement screws (see Installation Prerequisites on page 7).
Insert the right index cover mounting screw and tighten the screw enough to hold it in place. Do not
completely tighten.
Install the left index cover mounting screw and tighten to a snug fit. Finish by tightening the right
mounting screw to a snug fit. Tighten each mounting screw evenly.
Important Meter manufacturers: torque the mounting screws 15 to 20 inch-pounds.
