(2) After setting the oscillation adjustment register, 1Hz clock period changes every 20seconds ( or every 60
seconds) like next page figure.
1Hz clock pulse

T1
1 time
19 times
Measure the interval of T0 and T1 with frequency counter. A frequency counter with 7 or more digits is
recommended for the measurement.
(3) Calculate the typical period from T0 and T1
T = (19
×
T0+1
×
T1)/20
Calculate the time error from T.
