Elster American Meter Installation
To program the ERT module assembly
1. Program the meter drive rate into the 100G series gas ERT module using the endpoint programming
device.
2. For all programming and Check Endpoint operations, hold the handheld programmer as close to vertical as
possible. For optimal results, keep the handheld programmer within 6 feet of the target ERT module.
3. 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.
4. Programming parameters are based on the configuration file loaded into the ERT module programming
device. During programming, the 100G 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 module assembly will read
to the nearest cubic foot.
Attaching the 100G ERT Module Assembly to the Meter
After you program the 100G, attach the ERT module assembly to the Elster American meter.
Warning For 5B-225 aluminum meters only: cut 1/16-inch off each ERT wriggler post to prevent
the wriggler from rubbing on the face of the nut holding the meter drive dog in place. Trimming the
drive post may make the module incompatible with other 2-ft. drive meters.
To attach the ERT module to the meter
1. Align the ERT wriggler to connect with the drive post (or slot) of the meter.
• For one-foot meters: Align the ERT assembly wriggler perpendicular to the meter drive post.
• For two-foot meters: Align the ERT assembly wriggler perpendicular to the meter drive slot. The pin
on the ERT wriggler may be installed inside or outside the meter drive slot. For easy assembly, Itron
recommends installing the pin on the 100G wriggler outside the meter drive slot.
Warning Failure to correctly align the meter drive post and ERT module drive slot can cause binding
and lead to poor registration or meter failure. If there is a gap between the ERT module gasket and the
meter, it may be the drive slot of the ERT module assembly's wriggler is not correctly aligned with the
meter drive slot. Remove the 100G assembly and repeat the alignment procedure. You must engage the
ERT module wriggler with the meter drive dog.
