PARAMETERS
(5) Frequency setting voltage (current) bias/gain adjustment method
(a)Method to adjust any point by application of voltage (current) to across the terminals 2-5 (4-5).
REMARKS
⋅ If the frequency meter (indicator) connected to across terminals CA-PC does not indicate just 50Hz, set calibration parameter C0
CA terminal calibration. (Refer to page 251)
