Itron Meter Installation
The ERT module is programmed based on the meter's drive rate. Take note of the index drive rate shown on
the drive dial on the index. The ERT module is programmed based on the drive rate. Sprague meter index
drive rates are typically 2-cubic feet.
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.
Installing the 100G Gas ERT Module Assembly on the Sprague 175RM
Meter
After you program the 100G, install the ERT assembly on the Sprague 175RM meter.
To install the ERT module on the 175RM meter
1. Align the module wriggler (1) with the meter's drive dog (2).
Warning Failure to properly align the ERT wriggler with the meter drive post can cause binding and lead
to poor registration or meter failure.
