TIME-OF-DAY CLOCK CHIP

DANIEL INDUSTRIES MODEL 2500 microcomputer units that have a
time-of-day clock chip will continue to provide the time even when the unit is
without power either because of a power failure or because the instrument is in
storage.
When the MODEL 2500 is in operation, the clock chip is updated several times a
day as follows:
- Approximately two-hour intervals
- Shortly after midnight each day
- Whenever the time of day is changed
The clock chip is additional and secondary to the time of day maintained by the
software clock, which is an integral part of the MODEL 2500 operating system.
