Section IV - Operating Procedures

Trending -

The trending screen is a graphical display

of the compressor operation over the

previous 6 hours (samples taken every

minute).
The lines indicate pressure (dark, solid

line), temperature (dark, solid line), and

calculated horsepower (gray, broken line)

and are plotted from right to left (leftmost

values being most recent).

The scale on the left indicates the plotted

value and the scale along the bottom, is

the sample number.
The control buttons allow the graph to be

viewed in varying frames (from all 6 hours

at one time to expanded sections that may

be scrolled left or right).
