Figure 4.7 LCD Display with Segment Check
The three triangle segments in the bottom right corner of the display represent a
watt disk emulator. This electronic load indicator will advance with each pulse,
since each pulse is equivalent to one watthour. Reverse power is indicated by a
reversal in the direction of the electronic load indicator.
Stepper Motor Revision
As of May 2000, the stepper motor connector on the CENTRON C1S Clock and
Cyclometer personality modules, as well as the mating connection point on the
metrology board was revised. This revision, as shown in Figure 4.8 below, will
increase accessibility when removing or installing the registers.
