Remove Existing Cover & Prep Meter

• Remove the existing index cover

and index from the meter.

• Clean the meter index area

and make sure to remove any remaining parts of the old gasket.

9

Attach the Tamper Magnet Holder

• On an American meter,

attach the magnet so that the protrusion holding the magnet points down and to the left and the gap in the circle fits around the notch on the meter.

American

• On a Rockwell meter, attach the

magnet holder so that the protrusion holding the magnet points down and to the left and the inner pin is inserted into the index screw hole.

Attach Meter Index to IMU

• Align the IMU drive train

with the index wriggler.

Index Wriggler

11

Attach Meter Index to IMU (cont.)

• Use the two index screws

to firmly attach the index to the IMU.

• Torque:

– Rockwell: 13-15 inch pounds – American: 14-17 inch pounds

• Rotate the IMU drive train two turns,

clockwise or counter-clockwise to ensure it spins freely.

12

Attach IMU Assembly to Meter

• Insert the four cover screws

through the index cover and set the cover down.

• Attach the IMU assembly to

the meter so that the drive train aligns with the meter wriggler and the screw holes on the meter align with those on the cover.

13

Attach IMU Assembly to Meter (cont.)

• While holding the enclosure

against the meter to maintain proper alignment, rotate the test hand to verify proper engagement.

• Attach the index cover and

screws to the meter.

• Torque:

– Rockwell: 17-20 inch pounds – American: 25-35 inch pounds

• Tighten the four screws firmly.

• Use the nut driver to push the

two red tamper seals into place.

14

Prepare the IMU for Programming

• Slowly pass the service magnet once (for 2 to 5 seconds) over the top of the IMU.

• Doing so wakes up the IMU, enabling you to program it.

Remove the Index Cover and Index

1. Remove the existing index

cover and index from the meter.

2. Clean the meter index area

and make sure to remove any remaining parts of the old gasket.

21

Fasten the Adapter Plate to the Meter

1.Position the adapter plate pin

into the center left hole on the meter and seat the adapter onto the meter.

2.Position an index screw in the

center right hole and fasten the adapter using 7-8 in-lbs of torque.

22

Fasten the Adapter Plate to the Meter (continued)

4. Rotate the gear on the plate clockwise until you feel it engage with the

gear inside the IMU. Make sure that the gears are not locked up.

23

Fasten the Meter Index to the IMU

1. Attach the meter index to the IMU with

two index screws using 7-8 in-lbs of torque.

2. Make sure that the gears engage by

moving the lower dial.

24

Fasten the IMU to the meter

1. Angling in from the left, seat the

IMU on the adapter plate on the meter. Adjust the rear gasket as needed and make sure that the gears are engaged but not locked up.

2. Rotate the lower dial to make

sure it is engaged with the gear on the adapter.

25

Fasten the index lens cover and the tamper seals

1. Fasten the lens cover and the IMU

to the meter using the four long lens cover screws and a torque of 13-15 in-lbs.

2. Use a nut driver to push the three

tamper seals into the openings on the IMU.

26

Prepare the IMU for Programming

Slowly pass the service magnet once (for 2 to 5 seconds) over the top of the IMU. This activates the IMU so you can program it.
