The Elster Power Master Unit (PMU) software is a specialized, utility-grade application developed by Elster Metering Systems (now part of Honeywell ). It serves as a central hub for configuring, commissioning, and managing a wide range of Elster electricity meters across commercial, industrial, and domestic applications.
The specific version of PMU required depends heavily on the model of the meter being serviced. While Elster has historically provided this software for free on physical media, digital copies are often hosted on specialized utility forums or through official support channels.
