This screen displays the measurement type, value and engineering units in digital format.
Bottom line displays either Power or Temperature depending on selection.
This screen displays the measurements in the same order as in SCREEN 1, but this time
displays the value, engineering units and a bar graph which corresponds to the value
indicated. The bar graph is scaled from zero to the maximum value for the tester (see below).
Bottom line displays Power or Temperature depending on selection.
NB. Analogue bars update @14Hz to provide a visual indication of rapid activity.

This screen is used for testing pump volumetric efficiency. The screen initially displays flow
and pressure on the top two lines as in SCREEN 2 and power on the bottom two lines. Once
the efficiency reference point has been captured, then the third line displays the current
efficiency and the bottom line shows the reference point, the top two lines will continue to
display the current flow and pressure.
Screen 4 (Data Review)
This screen displays any recorded parameters and provides delete options.
