Web Interface Overview

4.5Sensor Names and Status

The Web interface displays four items about sensors in all windows available through the Summary, Sensors and Power tabs, as shown in Table 10.

The sensor’s Name is an optional user-defined description; the Description is created at the factory and cannot be changed. The Status and Current Value reflect the most recent sensor reading and are color-coded for easy identification. Status is determined by the thresholds that may be configured by the user.
