Analog Scaling Factor
The Scaling Factor is a method of adjusting the 4-20mA profile by using a multiplication
factor.
Press +/- from the HOME screen to access the scaling factor.
Use the +/- keys to enter a multiplication factor. A figure of 1.00 will not alter the
4-20mA profile. A figure of 2 will double the flow rate output from a specific mA
signal. A figure of 0.5 will halve the output.
Press SELECT once you have chosen the required factor.
Press ACCEPT to confirm the new 4-20mA PROFILE figures. This will not alter the
stored A and B points, the multiplication factor will re-scale the 4-20mA profile. To
re-set the original flowrates re-set the multiplication factor to 1.00.
