Testing the R900i SP Pit 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 appears 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:
• 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 Pit Installation
1 Read the MIU one more time before leaving the site to ensure

2 Make sure the appropriate ID# on the MIU has been assigned

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.
