Real Time Clock
The Series 500 Real Time Clock offers the following
set of features:
• Accuracy to within 45 ppm over the range O°C -
45°C. Note: 45 ppm is approximately 2 min.lmonth.
• A "keep alive" time of 30 days (nominal) and 10
days (worst case).
• Provides date and time of day.
Models 530,540 and 550
The Models 530 and 540 use the same Memory
Processor Module as the Model 520 but they are
packaged in either an HP System II rack-mount enclosure
or in a stand-alone mini-cabinet. The Model 550 is housed
in a small package, 325 mm wide. Modular packaging is
useful for workstations and multi-user applications that
have specific peripheral requirements.
