Itron Inc. 500GR Manuel D’Utilisation

11. Tilt the acetone stick vertically with the applicator foam end down. Squeeze the acetone stick on

the black dot until the packet inside the pen breaks. Continue to hold the pen in a vertical position

until the acetone wicks into the foam applicator end. Apply a thorough coat of acetone to the index

where the encoder will be installed. Do not touch the area where the acetone was applied before

the encoder is installed.
12. Slide the thin end of the encoder spacing tool down over the magnet hub.

13. Peel the protective plastic away from the

adhesive side of the encoder.

Important: You must do the next two steps exactly as described or the 100G series remote gas
module will not work properly.

14. Press the curved side of the encoder firmly against the side of the encoder spacing tool as

shown below, with the adhesive side down. Slide the encoder down along the side of the encoder

spacing tool until it touches the surface of the index (as shown below). Using moderate pressure,

hold the encoder firmly against the index, without moving, for 15 seconds to permanently apply the

encoder.

15. Remove the encoder spacing tool and lay the

index on a flat, horizontal surface to reduce strain

on the encoder cable.

16. Program the index reading (with the encoder mounted) into the 500G remote module. Read the

remote module and verify that the reading matches the read programmed into the remote module.
17. Use the correct replacement gasket for your

meter's index. Remove the gasket center and

index cover-hole plugs from the new gasket.

Insert the index and encoder assembly through

the gasket center with the gasket's adhesive-

backed side facing the meter.
