Chapter 4 Using the MRX920 Unit
Using the MRX920 unit to collect readings begins with the host
software building a route file that is transferred to the MRX920
unit via the USB flash drive. The meter reader inserts the USB
flash drive in the MRX920 unit and begins automatic meter
reading by driving the vehicle through the route and collecting
readings. After the readings are complete, the meter reader
returns to the utility, shuts down the MRX920 unit, and removes
the USB flash drive to give it to the host computer operator. The
host computer operator transfers the data from the USB flash
drive to the host computer software and transfers the data to the
utility billing system computer.
Reading Meters
Because the MRX920 automatically reads meters, efficient use of
the system depends on two factors:
• the distance of the MRX920 unit from the MIU being read.
• the vehicle’s driving speed.
In a typical meter reading scenario, you drive your vehicle through
the routes listed on the route selection screen in any order. You
can position your vehicle at any route or starting address as
required by driving conditions and route distribution for the most
efficient data collection. The MRX920 unit reads and stores
readings regardless of the order of the routes displayed.
