Attaching the 100G Datalogging Gas Endpoint Assembly to
the National/Lancaster Meter
After the 100G Datalogging Gas Endpoint has been programmed, attach it to the
National/Lancaster meter.
To Attach the 100G Datalogging Gas Endpoint
1. Align the white wriggler (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 engage endpoint wriggler in the meter drive
dog.
3. Install endpoint to meter mounting screws in an alternating fashion. 100G
Datalogging Gas Endpoints for National/Lancaster meters come with new, different-
size endpoint mounting screws (SCR-0014-004 - see Installation Prerequisites on page
8 for screw information.) 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. Each endpoint mounting screw must be tightened
evenly.
Important Meter manufacturers should torque the mounting screws 15 to 20
inch-pounds.
