8. By using an Handheld 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. For Rockwell 415 Transponders Only: Install the meter
adapter to the meter using the two 6/32 supplied in the
assembly. Note: Make sure the gears on the adapter and meter
are properly meshed.
2. Visually align transponder wriggler with meter wriggler or meter
adapter (drive dog).
• If wriggler cannot be put in a fixed position, position it
correctly by rotating the drive dial with your finger.
3. Mate the transponder wriggler with the meter wriggler or meter
adapter (drive dog) and hold the mated assembly against the
meter.
4. 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 Elster Integrated
Solutions.
