7.2.3 Clock Accuracy
The clock built into the PS-B (RTC) has a slight error. The error is ±180 seconds
per month when the PS-B is turned off and kept under normal temperature. How-
ever, the error may become as large as ±300 seconds per month depending on the
temperature differences and years of service. If using the PS-B in the system in
which clock accuracy is vital, be sure to adjust the clock periodically.
Clock Accuracy ±180 seconds/month
