Diaphragm Meter Installation
The photo below shows how the encoder spacing tool and encoder will look after the 15 second wait time.
18. Remove the encoder spacing tool and lay the index on a flat, horizontal surface, to diminish strain on the
encoder cable.
19. Program the index reading (with the encoder mounted) into the 100G series remote gas module.
20. Read the 100G series remote gas module. If this reading is the same as the reading programmed into the
100G series remote gas module, the ERT module is programmed correctly.
Index Cover Installation Required Materials
Use the correct replacement index cover gasket for your index (see Replacement Gaskets for Itron 4-hole, 2-
hole, or 1-hole gasket part numbers).
To install the meter index covers over the 100G series remote gas module encoder cable
1. Remove the gasket center and index cover hole plugs from the new gasket.
2. Insert the index/encoder assembly through the gasket center. Verify the gasket's adhesive-backed side is
facing the meter face.
3. Align the index wriggler with the meter's drive dog. Install the index on the meter using the index
mounting screws. Tighten one index screw two turns. Install and tighten the remaining index screw.
Tighten the first index mounting screw completely (alternating fashion).
