ADJUSTMENT PROCEDURE:
1. With no input, adjust Bias (n061 setting) until an output of
0.0 Hz is obtained.
2. With full scale input, adjust Gain (n060 setting) until an output
of 60.0 Hz (or other desired max. output frequency) is obtained.
NOTE: Follow the same adjustment procedure for other desired frequency setpoints.
For inverse-acting frequency reference
1. Begin with n060 & n061 settings as shown below.
2. Fine tune as indicated above.
