Fig. 6-83: Signal adjustment of terminal 2
Fig. 6-84: Signal adjustment of terminal 4
There are three methods to adjust the frequency setting voltage (current) bias/gain:
● Method to adjust any point by application of voltage (current) to across the terminals 2-5
(4-5). (Refer to page 6-157.)
● Method to adjust any point without application of a voltage (current) to across terminals 2-5
(4-5). (Refer to page 6-158.)
● Adjusting only the frequency without adjusting the voltage (current).
(Refer to page 6-159.)
NOTE
When voltage/current input signal for terminal 4 was switched using Pr. 267 and voltage/cur-
rent input switch, perform calibration without fail.
