R900 Wall and Pit MIU Installation and Maintenance Guide 21
Testing the Installation
To test the installation, complete the following steps.
1 Power up the handheld unit (HH with HHIU) and put in RF
test mode.
2 When the MIU is installed correctly, its ID number(s) and
meter reading(s) appear on the display of the HH. Verify the
correct meter reading(s) by comparing it to the meter’s dial. If
the readings are the same, proceed to the next section.
3 If a meter reading does not appear on the HH’s display, or the
meter reading in the HH’s display is not the same as the read
-
ing on the meter’s dial, do one of the following:
• Reactivate the MIU using the magnet.
• Verify all electrical connections.
• Verify registers are programmed correctly.
• Test the installation again.
4 If a ProRead (ARB VI) Encoder Register is used:
• Ensure the unit is programmed in 3-wire mode.
• Verify all electrical connections.
• Reactivate the MIU. (See Step 1.)
5 If an ECRIII register is used, make sure the register is pro-
grammed in a
compatible format.
If a problem still exists, contact your Neptune Sales
Representative.
To avoid RF signal saturation of the HH, do one of the following:
• Position yourself at least two to three feet from the MIU.
• Remove the antenna from the HH.
Activating the MIU with a magnet is recommended, but not a mandatory step.
The R900 automatically checks every eight (8) hours for the presence of a reg
-
ister. If one is detected, the MIU wakes up and starts transmitting.
