EXAMPLE 1:
Variable value= OUTPUT FREQUENCY, range= 0-100 Hz
Range needed for output= 0-50 Hz
Output signal 0 or 4 mA is needed at 0 Hz (0% of range) - set par. 6-51 to 0%
Output signal 20 mA is needed at 50 Hz (50% of range) - set par. 6-52 to 50%

It is possible to get a value lower than 20 mA at full scale by programming values >100% by using a formula as
follows:
