Operation: C1SD, C1ST, and C1SL Versions
5-2 CENTRON Meter Technical Reference Guide
• Self-Read Capability—Billing data can be stored automatically at
programmable times to be read later.
• Load Profile—The C1SL module provides 32K RAM for load profile data.
• Expansion Capability—An expansion port is available for future functions.
• Bidirectional Metering—All three multifunction versions are capable of
measuring and displaying forward and reverse energy only (kWh). These
modules have two separate registers; one for forward kWh and one for reverse
kWh. When the meter is programmed with electronic detent, both the forward
kWh register and the reverse kWh register will be utilized. When the meter is
programmed to be undetented, the forward and reverse energy will
accumulate in the forward kWh register.
The C1SD, C1ST, C1SL modules are available with an LCD display and a
polycarbonate cover. The cover contains the optical port adapter and demand
reset button.
