쑶
Example
쑴
The frequency of the maximum analog voltage of the potentiometer (at 5V) has to be
changed from the initial setting of 50Hz to 40 Hz. Set 40Hz in Pr. 125.

Change the frequency of the maximum analog value
NOTES
Set the frequency at 0V using calibration parameter C2.
As other adjustment methods of frequency setting voltage gain, there are methods to adjust
with a voltage applied to across terminals 2-5 and adjust at any point without a voltage
applied. (Refer to section 6.20.5 for the setting method of calibration parameter C4.)
Turn the digital dial until P.125 (Pr. 125) appears.
Press the SET key to show the currently set value.
The initial value "50.00" (50.00Hz) appears.
Turn the digital dial to change the set value to
"40.00" (40.00Hz).
Press the SET key to set.
Press the MODE key twice to choose monitor/
frequency monitor.
Turn the start switch (STF or STR) on and turn the
volume (frequency setting potentiometer)
clockwise to full slowly. (Refer to Fig. 5-32,
