External operation
5.3.4 Change the frequency (40 Hz) of the maximum value of potentiometer (at 5 V)
Example
The frequency of the maximum analog voltage of the potentiometer (at 5 V) has to be changed
from the initial setting of 50 Hz to 40 Hz. Set 40 Hz in Pr. 125.
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" (50.00 Hz) appears.
Turn the digital dial to change the set value to
"40.00" (40.00 Hz).
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. 5-27,

NOTES Set the frequency at 0 V 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 6.16.3 for the setting method of calibration parameter C4.)
