The
HP
81 12A
Is not designed for outdoor use. To prevent potential
fire or shock hazard, do not expose the
HP
81 12A
to rain or other
excessive moisture.
The HP
8 1 12A
may be operated in temperatures from 0°C to 55°C.
The HP
8 1 12A
may be operated in environments with humidity up
to 95% (0°C to +40°C). However, the HP
81 12A
should be protected
from temperatures or temperature changes which cause condensation
within the instrument.
The HP
8 1 12A
is equipped with a cooling fan mounted inside the
rear panel. The instrument should be mounted so that air can
freely circulate through it. When operating the HP
8112A,
choose a
location that provides at least 75 mm
(3
inches
)
of clearance at the
rear, and at least
25
mm
( 1
inch
)
of clearance at each side. Failure
to provide adequate air clearance will result in excessive internal
temperature, reducing instrument reliability.
If
physical damage is evident or if the instrument does not meet
specification when received, notify the carrier and the nearest
Hewlett-Packard Service Office. The Sales
/
Service Office will arrange
for repair or replacement of the unit without waiting for settlement of
the claim against the carrier.
