8. By using an SRP or other suitable interrogator/programmer,
verify that the pre-divider is correct. (The pre-divider for a 1-ft
drive is 100 and the pre-divider for a 2-ft drive is 50; refer to the
Appendix for the definition of pre-divider).

9. Remove any subcounts or counts from the mechanical index by
rotating the drive dial clockwise by the same number of counter-
clockwise rotations that were placed on the mechanical index in
the previous steps.

Mounting the Transponder/Index Assembly
NOTE: Be sure to have your transponder/index assembly,
screwdriver, index cover and index cover gasket within easy reach
before starting this procedure.
1. Visually align transponder wriggler with meter wriggler (drive
dog).
• If wriggler cannot be put in a fixed position, position it
correctly by rotating the drive dial with your finger.
2. Mate the transponder wriggler with the meter wriggler (drive
dog) and hold the mated assembly against the meter.
3. While holding the assembly against the meter, gently try to turn
the drive wheel clockwise, then counterclockwise.
• If the drive wheel meets resistance in both directions, it is
properly mated. Proceed to Step 4.
• If it meets no resistance in either direction, and can rotate
freely through an angle of 360 degrees and beyond, then
make sure the meter is completely free of old gasket
material and forcefully press the transponder into the meter.
Repeat this step (Step 3). If the unit still does not correctly
engage with the meter, return it to AMCO Automated
Systems.

Repeat this step (Step 3). If the unit still does not correctly

Systems.
• For AMCOAS Transponders Only: If the AMCOAS
transponder meets resistance in one direction then turns
360 degrees the other way before again meeting resistance,
it is not properly mated. Repeat from Step 1.
360 degrees the other way before again meeting resistance,
it is not properly mated. Repeat from Step 1.
CAUTION: It is very important that the wriggler on the
transponder is correctly engaged onto the meter. If it is not, it
could produce an erroneous indication during utility leak test
procedures that monitor drive dial (proving dial) movement.
Incorrectly engaged wrigglers could also cause meter damage.
CORRECT EXECUTION OF STEPS 1, 2 and 3 IS CRITICAL.
4. Verify that the gasket material on the index cover is free of rips
or tears.
• If it is not, remove the damaged gasket from the index cover
and replace with a new one.
