To assemble the 100G Datalogging gas endpoint and index
1. Separate the 100G Datalogging gas endpoint housing from the cover by pulling the cover straight out from
the housing.
2. Set the endpoint cover aside where it will not be damaged or fill with rain, dirt or snow. You will use the
cover later in this installation procedure.
Caution Use only dial-type indexes from National (or Actaris/Schlumberger/Sprague) Meter
with the 100G Datalogging gas endpoint.
Indexes with bow-tie shaped wrigglers are not compatible with 100G Datalogging gas
endpoints. Obtain a compatible index.
