Temperature
The HP 8153A may be operated in temperatures from O^C to 55“C.
Humidity
The HP 8153A may be operated in environments with humidity up to 95%
(O^C to +40°C). The HP 8153A should be protected from temperatures or
temperature changes that cause condensation within the instrument.
Instrument Cooling
The HP 8153A has a cooling fan mounted internally. Mount or position the
instrument so that air can circulate through it freely. When operating the HP
8153A, choose a location that provides at least 75mm (3mches) of clearance at
the rear, and at least 25mm (linch) of clearance at each side. Failure to provide
adequate air clearance may result in excessive internal temperature, reducing
instrument reliability.
