Transducer Control 5 User Manual (RWT3746IM)
Revision 7, September 2020 - Page 14
Data Ranges
The data range parameters control how data from the selected internal variable is
taken and scaled. This feature is useful when the user is working in a specific
measurement area and requires a greater change in analog output.
The low and high range values effectively rescale to the Zero and FSD voltages
set in the Analog Voltage Scaling section. Values that fall below or above the range
are masked off; the range selection applies to both negative and positive sides.
Data Range
The user can select a default scale or opt for a custom scale, by selecting from the
“Data Range” combo box.
Default FSD Range
The “Default FSD Range” option scales the selected internal variable based
on the FSD rating programmed into the transducer, i.e. 0 to FSD.
User Defined
The “User Defined” option allows the user to adjust the “Range Low” and
“Range High” sliders to select a custom scale.
Range Low / Range High
The
“Range Low” and “Range High” slider bars control the low and high scale
values. The “Range Low” parameter can be set between 0 and 80% of FSD, and
the “Range High” parameter can be set between 20% and 100% of FSD. The
parameter value is displayed in a text box to the right of each range slider. The
value is displayed in an appropriate unit for the selected data variable, i.e. Torque
= Nm or the configured unit, Speed = RPM, Power = Watts.
To change the high or low range values adjust the slider bar to the left or right until
the number in the text box equals the required value. The difference between the
“Range Low” and “Range High” must be greater than 10% of FSD and “Range
High” must be a higher value than “Range Low”.
