Description of function
'SCALE-t' Total Scale Factor
Defines the arithmetic relationship
between the rate and total
displays. May be adjusted
between 0.0001 and 65535
SCALE-t = Units of rate display
Units of total display
To calculate SCALE-t the required
units of measurement for the total
display must be converted to the
units of measurement used for the
rate display.
See section 5.13, 6 and Fig 6.
'CLIP-OFF' Percentage Clip off
To prevent totalisation at very low
flow rates, this function enables
the user to select a percentage
rate below which the rate display
is forced to zero. Adjustable
between 0 and 10% of flow for
linear inputs, and 5 to 10% when
the root function is used to
linearise a square law input.
See section 5.14
