Display Functions
The LCD is configured for five digits of energy consumption and will rollover at
100,000 kWh. The LCD is automatically adjusted for contrast over the operating
temperature range.
A watt disk emulator is located on the lower right hand corner of the display. The
indicator consists of three square segments in the lower right-hand corner of the
display, which scroll in the direction of energy flow. Figure 7.3 below illustrates
this revision.
