Troubleshooting
The following table offers troubleshooting tips for some common
Transponder conditions. For all other matters, contact AMCO Automated
Systems.
Symptom Possible Cause Solution
The incorrect serial number has been
entered into the interrogator
Verify that the correct serial number is being
interrogated
The transponder is not within range of
the interrogation device
Be certain that the interrogator is within range of
the transponder. An SRP should be within 3
inches of the transponder. If operating an MMI in
Lat/Long or GEO Mode be certain that the
transponder is in the reading window.
Interference from another interrogation
device.
Verify that no other interrogations are taking
place, either with an SRP, PI, URFI, or MMI.
Transponder cannot be
interrogated with an SRP, MMI or
PI Device
Interference from another interrogation
device.
Any MMI within range of the transponder must
have the transmitter turned off while you are
interrogating with the SRP.
The SRP is out of range of the
transponder.
Move the SRP (and particularly the top, where
antenna resides) closer to the transponder.
Transponder will not program
The programming device (SRP, PI) is
attempting to communicate with the
incorrect transponder serial number
Correct the serial number in the programming
device.
Malfunctioning Interrogator Check operation of interrogator on known good
transponder
Interference from external sources Clear area around transponder of metal objects
(lawn chairs, bicycles, etc.).
Transponder will not read from
street
Hard-to-read location Place a known good transponder at the same
location and attempt to read both units from the
street. If the new unit will read replace the old unit
and reinstall it on a meter with shorter range
requirements.
Tamper flag will not reset The orientation of the transponer at the
time it was programmed is different from
the current orientation of the transponer.
Reprogram the e-index reading. This will reset
the tamper to “false” and establish the “no tamper”
position of the transponder.
I rotated the drive hand forward
three times and back three times
but the subcount increased
anyway.
Transponders will accumulate
subcounts with rotation of the drive hand
in either the counterclockwise or
clockwise direction.
If the index is rotated in reverse during installation
and/or troubleshooting procedures the
transponder should be reprogrammed to the
current index reading to reset subcounts to zero.
