Extended Tamper Flag
(retrievable with two-way communication).
Low Battery Warning. The 100W-R and 100WP-R ERT modules include a battery life estimator. The
estimator is based on the number of data packets sent at the various power levels and the age (self-
discharge) of the ERT module. The low battery warning allows the utility to easily identify which
ERTs are nearing end-of-life in a mixed population and gives the opportunity to schedule replacement.
The low battery warning is a single flag set when the battery has less than 10% remaining capacity,
typically 2 years life remaining Battery life is evaluated daily at midnight.
Cut Cable Flag
.
100W-R encoder ERT module. The Cut Cable Flag sets if the LGR Flag is active for 24 hours.
100WP-R pulser ERT module. The Cut Cable Flag sets if the LGR Flag is active for two consecutive
times.
The Cut Cable Flag remains active for 40 days in Mobile mode.
The Cut Cable Flag remains active for 24 hours in Fixed Network mode.

Battery Life
Powered by two non-replaceable, long-life lithium batteries, the 100W has an expected battery life of 20 years
when the ERT module operates in default Mobile or Fixed Network Operating mode. If the 100W series ERT
module is programmed for Hard to Read Mobile Mode, the battery life is reduced to 13 years. To proactively
indicate the battery has reached a <10% useful battery life, a
Low Battery flag
is set to indicate impending
battery failure. Battery life is 15 years for the 100WP-R when ERT module cable lengths exceed 150 feet.
