When a meter fails or displays an error code, the PMU software provides the diagnostic depth needed to identify the issue. Technicians can view internal diagnostics that aren't visible on the meter’s liquid crystal display (LCD). Seamless Integration
For installations that include external modems or other peripherals, the PMU provides configuration options for the serial port power supply. The software supports three modes: disable serial port power (power for the modem is disabled), always power serial port (power to the modem is permanently enabled), and interrupt serial port power (power is interrupted for 20 seconds at a programmable interval between 1-24 hours). This granular control helps ensure correct operation of connected devices while preventing power-related issues. Elster Metering Systems Power Master Unit Software
The software can convert legacy Master Unit files to ensure continuity with older metering systems. Security Features When a meter fails or displays an error
