Testing the R900i SP Inside Installation
After the MIU has been installed, follow these steps to verify that
the MIU is working properly.
1 Power up the handheld unit (HHU) test device to start the
testing program provided.
2 When the R900i SP is installed correctly, its MIU ID#
and a meter-reading appear on the HHU’s display within one
minute. Verify that this is the correct meter reading by comparing
it to the meter’s dial.
3 If a meter reading does not appear on the HHU’s display, or
the meter reading in the HHU’s display is not the same as the
reading on the meter’s dial, do the following:
• Reactivate the MIU by using a flashlight to activate the
photo sensor light.
• Verify the battery is connected.
• Test the installation again (repeat steps 1 and 2).
Completing the R900i SP Inside Installation
1 Read the MIU once more before leaving the site to ensure MIU
is transmitting.
2 Make sure the appropriate ID# on the MIU has been assigned
to the meter setting.
To avoid RF signal saturation of the HHU, position the receiver at least 2
to 3 feet from the MIU. In a densely saturated area, removing the antenna
from the handheld can assist with readings.
A register reading of 8 digits will be returned.
The light sensor is located under a small recess near the center of the dial
plate. This recess is denoted by a flashlight symbol on the dial plate.
