Power Source: Two 1.5-volt watch cell batteries powerthe dispiay, and a third 1.5-volt battery
powers the internal circuitry.
Weight:
Approximately 170 grams (6 ounces).
Time Accuracy:
The HP-01 time function was set at the factory to an initial accuracy of within
30 seconds per year. Because of the effects of temperature variations, aging, shocks, and
vibrations on its quartz-crystal time standard, the HP-01 time accuracy may vary.
Stopwatch Resolution:
+0.01 second.
Operating Temperature:
0° to 55°C (32° to 131°F). When worn on the wrist, the HP-01
battery operating temperature will remain relatively close to body temperature even though the
ambient temperature may be far below freezing.
Storage Temperature:
Without batteries:
—40°to 75°C (—40° to 167°F).
With batteries:
—40° to 55°C (—40° to 131°F).
Anti-magnetic:
The HP-01 will operate in a magnetic field up to 60 gauss without adverse
effect.
