REX Meter
2 Product Description Technical Manual
2-6 30 November 2006
The load profiling interval is specified in minutes and must be 15, 30, or 60
minutes. The load profiling interval length can be different from the demand
interval length.
Note: If the metered quantity is kWh net, load profiling stores the
number of kWh delivered pulses.
K
h
pulse divisor. A pulse divisor is used to scale down the number of K
h
pulses recorded in each load profiling interval. This allows recording of data that
may exceed the maximum number of pulses that can be stored in each load
profiling interval (each interval can store 4095 pulses before overflowing).
The standard value of K
h
for all REX meters is 1.0. If the divisor is set to 10, then
each load profiling pulse count represents 10 Wh.

■ meter cover
