Note National/Lancaster meter indexes are available in different models:
Some National/Lancaster Meter indexes have index legs
to mount the index on the
meter or endpoint. Some indexes have both legs and index mounting holes and
some have just mounting holes. Mounting methods are dependent on the index.
Index types require different mounting screws to attach the index to the 100G
Datalogging Gas Endpoint housing (see
Installation Prerequisites on page 8).
Indexes with legs must be mounted to the endpoint housing mounting posts.
Indexes with mounting holes must be attached to the endpoint housing's bracket
mounting posts.
1 Bracket mounting posts (indexes with legs)
2 Housing mounting posts (indexes without legs)
