Programming the module using the EA_Installer
Although modules may contain default or utility-specified values that are programmed during manufacturing, it is important to program
certain data only after the module has been installed in the field:
• Modules can accumulate subcounts during shipping, handling and installation due to the movement of its wriggler.
• The module’s tamper sensing switch must be told which orientation should be considered its normal (not tampered) condition.
• During a field module retrofit the meter’s existing index is reused and that index reading must be programmed into the module.
Therefore, all modules (even those mated with indexes set at 0000) should be programmed after installation on the meter.
Note: If required, be sure to have the module’s pressure compensation factor. Contact Elster Support at [phone].
For specific instructions for installing and programming modules using Elster’s EA_Installer handheld please refer to the Elster Handhelds
