AMR Transmitter Installation
Installation Tasks
1. Remove index cover.
2. Remove index from gas meter.
3. Mount AMR transmitter onto gas meter.
4. Assemble index and cover onto AMR transmitter.
5. Initialize AMR transmitter with HHT.
Remove index cover
1. Use small flat screwdriver to punch out the seals that cover two (2) of the
four (4) index cover screws.
2. Remove and properly dispose the four (4) screws holding the index cover
onto meter, with flat screwdriver. If two (2) or more screws shear off during
the cover removal (or were previously sheared off), the meter will need to be
replaced by a qualified utility representative. Reinstall any index cover
screws that were removed and cap with seals if possible. Enter the
appropriate information in the Mint HHT and skip to the next work order.
3. Remove the index cover and dispose of properly.

Remove index
1.
Remove and properly dispose the two (2) screws holding the index onto the
meter, with small flat or Phillips screwdriver.
2.
Remove the index and carefully clean any debris from it. Inspect for proper
index operation by turning the input shaft and verifying that the gearing turns
freely. Also, inspect the index for any missing or broken hands. Place the
index, or a new index if necessary, on a clean surface near you for
reinstallation later.
3.
With a putty knife, scrap away any gasket material that remained on the
meter when the index cover was removed.

Mount Transmitter on meter
Insure the four (4) mounting screws are available and within reach.
Place the AMR Transmitter onto the gas meter, aligning the Transmitter’s shaft
with the gas meter’s male or female wriggler; adjust the Transmitter shaft’s
position by holding it on the front side, and insert pin into hole.
1.
While holding the Transmitter in place, check that the shafts are aligned by
gently rotating the Transmitter’s shaft with your other hand. There should be
just a slight freedom of motion.
2.
Attach the Transmitter to the meter using the four (4) mounting screws with
#3 Phillips screwdriver. Place all screws, then torque down two (2) diagonal
screws. Check shaft alignment again, then tighten the last two (2) screws.
3.
Should two (2) or more screws shear or strip during the installation, the
meter will need to be replaced by a qualified utility representative. Remove
the transmitter and reinstall the index and index cover on the meter with the
original screws. Enter the appropriate information in the Mint HHT and skip
to the next work order.

Assemble index and new cover onto
transmitter
1.
Insure the two (2) index screws are available and within reach.
2.
Install the right side index screw to its place in the index (use tweezers if
more convenient). Skip this step if assembling a plastic index.
3.
Insert #1 Phillips screwdriver to hold screw in place, while placing the index
onto the Transmitter, then insert the screw just 2-3 turns, so that the index
fits loosely on the Transmitter. In case of a plastic index, or an index with
open screw positions, first insert the right screw 2-3 turns and then slide the
index mounting slot behind the screw head.
4.
Align the index male or female wriggler with the Transmitter’s shaft; adjust
the wriggler’s position by holding the proving hand on the index front side,
and insert pin into hole.

5.
Install (use tweezers) the left side index screw to its place in the index. Use
left hand to install the screw and secure index into place.
With plastic index:
6.
While the index is still a bit loose, centralize its position. Check that the
motion is smoothly transferred and there is no binding between the shaft and
wriggler, by gently rotating back and forth the index’s proving hand.
7.
Tighten the index screws, securing the index to the Transmitter.

8.
Install the index cover supplied (it only fits in one direction – the bump fits in
the right side of the Transmitter). Check that the gasket is properly aligned
and fasten to the Transmitter with the four (4) index cover screws.
CAUTION
Use care when working with a power screwdriver to insert
screws in the plastic Transmitter box. Over tightening will
damage the box and/or weaken the contact.
9.
Install the two snap seals in the index cover and insert fully with the aid of a
¼” nut driver. Align the end of the nut driver on the snap seal and tap the
end of the nut driver handle with your hand until it is fully seated.
