NOTE
• Always calibrate the input after changing the voltage/current input signal with Pr.73 (Pr.267) and the voltage/current input
selection switch.
 Frequency setting voltage (current) bias/gain adjustment method
 Adjustment by applying voltage (current) between terminals 2 and 5 (4 and 5) to set the voltage
(current) at the bias/gain frequency (Example of adjustment at the gain frequency)
