Range. The SRP’s range extends outward to approximately twelve (12)
inches from the top of the handheld unit. Actual communication range
may vary dependent upon environmental conditions.
Battery Life. The internal battery allows approximately 24 hours of
normal operation on a single charge. Recharging takes about 2 hours.
How the SRP Works
The SRP is both an interrogator (can talk to and receive information from
transponders) and a programmer (can program transponders). It sends
out a radio frequency (RF) signal embedded with special authorization
codes that the transponder recognizes, and thus establishes
communications with the transponder for performing various functions.
It is designed to operate at short range (within about 12 inches of the
transponder) for programming transponders with the current meter index
value (and other parameters) at the time of installation. This range
limitation helps ensure the SRP programs only the intended transponder
and reads back that same transponder’s status to verify its programming.
The SRP has functions built into its internal programming (firmware) that
allow the user to determine precisely which transponder is being read
and/or programmed. It also allows the user to search for a specific
transponder by serial number if there are a number of transponders in
the area.
With the SRP, the user can also determine and reset the tamper status
of transponders, read meter index data and synchronize transponder
time with SRP time.
