IIMSTRUMENT COOLING
The HP 3326A is equipped with a cool ing fan mounted on the rear panel. The HP 3326A
should be mounted so that air can freely circulate
through it. When operating the
HP 3326A, 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 ade
quate air clearance will result in excessive internal temperature, reducing instrument
rel iabi l ity. The fi lter for the cool ing fan can be removed for cleaning. The filter is re
moved by disconnecting the power cord and removing
the four knurled nuts (HP part
number 0535-0013). The filter (HP part number 3150-0218) should be removed and
cleaned by flushing with soapy water every thirty days.
