Programming defines the Eclipse’s personality. If the installer wants the unit to act
like an orange, he must program it to act like an orange. If the installer wants the unit
to act like an apple, he must program it to act like an apple. Of course, some creative
installers will program units to act like fruit salad. The Eclipse hardware can be used
in a wide variety of ways; how the hardware works depends upon how the unit is
programmed.
The program resides in the unit’s memory, in an area so small that it cannot be seen
by the human eye. If we were to magnify this area in our mind’s eye, we could think
of the program as a series of columns, with each column being made up of blocks,
as represented in the diagram below:
Each block has a name and a value, selected from a range of values, and each block
is associated with a particular programmable feature of the unit called a parameter.
In the program mode, the microprocessor is able to access these blocks, and
fortunately for all of us who are not Superman, put the names and their values up on
the display. Programming is accomplished by entering the “right” value for each
parameter. For instance, program block F1 is the K factor 1 parameter. If the flowme-
ter has a K factor of 25.3 pulses per gallon, the installer would enter 25.300 into this
block.
Each column contains parameters that are related to a general function of the Eclipse.
Column F (Factors) is made up of parameter blocks that handle the count and rate
scaling, which convert raw flowmeter pulses into meaningful count and rate dis-
plays. Column d (defaults) is somewhat of a miscellaneous collection of display
and totalizer mode parameters. It also contains the blocks where the default pro-
