Troubleshooting
The following table offers troubleshooting tips for some common SRP
conditions. For all other matters, contact AMCO Automated Systems.
Symptom Possible Cause Solution
Upon start-up, SRP displays
“RECHARGE BATTERY”
message.
Battery voltage too low. Recharge batteries.
Upon interrogation, SRP displays
the “CARRIER NOT DETECTED”
message and does not display
transponder data.
The SRP is out of range of the
transponder.
Move the SRP (and particularly the top, where
antenna resides) closer to the transponder.
The SRP is receiving outside
interference.
Move the SRP (and particularly the top, where
antenna resides) closer to the transponder. If
other TRACE readers or programmers are
operating nearby, wait until they have moved
away and try again.
Manually entered transponder serial
number is not valid.
Wait 2 seconds, re-enter the desired serial
number and interrogate again. If interrogation fails
again, check source of serial number and
verify/correct number.
Transponder is not responding to
interrogation signal.
Move the SRP (and particularly the top, where
antenna resides) closer to the transponder. If
other TRACE readers or programmers are
operating nearby, wait until they have moved
away and try again.
First History/TOU or Set Meter
Parameters program command
interrogation (VRT).
Interrogate for the second time.
Second or subsequent History/TOU or
Set Meter Parameters program
command interrogation attempted
beyond 1 minute timeout (VRT).
Restart command sequence by re-entering
transponder serial number in SN-ADR/CMD field
and interrogating. Repeat command
interrogation.
Upon interrogation, SRP displays
“READ DATA ERROR.”
The SRP is receiving outside
interference.
Move the SRP (and particularly the top, where
antenna resides) closer to the transponder. If
other TRACE readers or programmers are
operating nearby, wait until they have moved
away and try again.
Two or more transponders are within in
range of the SRP simultaneously.
Set the SRP (and particularly the top, where
antenna resides) directly on the desired
transponder.
