Elster American Meter Installation
2. Set the ERT module clear 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.
Note Elster American Meter indexes are available in different models:
Index wrigglers on one-foot meters with drive slots Index meters on two-foot meters with drive
posts
Index with mounting screw holes Index with mounting slots
If your index has mounting screw slots, skip steps 3 and 4. If your index has mounting screw holes,
perform steps 3 and 4, and skip steps 5 and 6.
3. Using the original index mounting screw or a replacement screw, if necessary, place one 8 - 32 3/16-inch
screw into the index's right-hand mounting screw hole.
4. Attach the screw to the ERT module housing's right-index mounting post just enough to hold the screw
and the right end of the index in place.
5. Screw one 8 - 32 x 3/16-inch screw into the right index mounting post loosely--one or two turns. Do not
tighten the screw.
6. Place the right index mounting screw slot under the screw head. Do not tighten the screw.
7. Slide the index drive post into the ERT module shaft slot. Verify positive engagement.
