Software:

Adjust the RTC
oscillation frequency
using the PC tuning
mode. Perform the
procedures below.
1. Apply 5V DC to the
“CLKC” terminal
of the control unit
(X53-412).
2. Measure the
output from the
“32KOUT” termi-
nal of the control
unit (X53-412)
using the calibrated
frequency counter.
3. Enter the measured
frequency value to
“Crystal Oscillation
Frequency” of RTC
correction in the
PC tuning mode
and then click [OK]
button.
Note:
It is not necessary to
adjust the RTC oscillation
frequency under normal ad-
justments.
The RTC oscillation frequency
must be checked and ad-
justed when the 32kHz crystal
resonator (X700) is replaced.
