To program the 100G DLS gas ERT module
Program the meter drive rate into the 100G DLS gas ERT module using the endpoint programming
device.
For all programming and Check Endpoint operations, hold the handheld programmer as close to
vertical as possible. For best success, keep the handheld programmer within 6 feet of the target ERT.
Verify you have the correct programming mode (Fixed Network Mode, Mobile High Power Mode,
Mobile/Handheld Mode, or Hard to Read Mobile/Handheld Mode) for your application.
Programming parameters are based on the configuration file loaded into the ERT module programming
device. During programming, the 100G DLS gas ERT module is set to the nearest 100 cubic feet; the last two
digits (tens and units) are programmed as zeros (0). After programming is complete, the ERT assembly will
read to the nearest cubic foot.

against the back of the screw.
4. Remove the screw completely after the index is free of the meter.
5. Set the index aside where it will not be damaged or fill with dirt, rain, or snow. You will mount the index
in the ERT later in this procedure.
6. Discard the index mounting screws. The 100G DLS for National (Lancaster) meters includes new,
different-sized index mounting screws (see Installation Prerequisites on page 12 for screw information).
7. Remove the old gasket, gasket residue, and dirt from the meter (if applicable). The meter face must be free

To assemble the 100G DLS gas ERT module and index
1. Separate the 100G DLS housing from the cover by pulling the cover straight out from the housing.
2. Set the ERT cover aside where it will not be damaged or fill with rain, dirt, or snow. You will use the
cover later in this installation procedure.
Caution Use only dial-type indexes from National, Actaris, Schlumberger, or Sprague meters with the
100G DLS.
Indexes with bow-tie shaped wrigglers are not compatible with the 100G DLS. You must use a
compatible index.
Note National (Lancaster) meter indexes are available in different models:
Some National meter indexes have index legs to mount the index on the meter or ERT. Some indexes
have both legs and index mounting holes and some have just mounting holes. Mounting methods are
dependent on the index. Index types require different mounting screws to attach the index to the 100G
DLS housing (see Installation Prerequisites on page 12). Indexes with legs must be mounted to the ERT
housing mounting posts. Indexes with mounting holes must be attached to the ERT housing's bracket
mounting posts.

If your index has legs with mounting screw slots, skip steps 3 and 4. If your index has mounting screw
holes in the index back plate (no legs), perform steps 3 and 4, and skip steps 5 and 6.
3. For indexes with mounting screw holes in the index back plate (no legs), use replacement index mounting
screws (SCR-0037-001, see Installation Prerequisites on page 12). Place one screw into the index's right-
hand mounting screw hole (1).
Note National index mounting screws are thread-forming screws and may require more torque.
4. Attach the screw to the ERT housing's right-index mounting post (2) just enough to hold the screw and the
right end of the index in place.
5. For indexes with legs (mounting slots), screw one 10 - 20 x 3/8-inch screw (SCR-0017-001, see
Installation Prerequisites on page 12 for screw information) into the right index mounting post one or two
turns. Do not completely tighten the screw.
