Overview
In order for the instrument to meet specifications, the operating
environment must be within these limits. Refer to
page 3.
The instrument is not designed for outdoor use. To prevent potential fire
or shock hazard, do not expose the instrument to rain or other excessive
moisture.
Instrument Cooling
The instrument has a cooling fan mounted internally.
Mount or position your instrument upright and horizontally, as shown in
the following figure so that air can circulate through it freely.
Operating Position
When operating the instrument 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 may
result in excessive internal temperature, reducing instrument reliability.
The instrument should not be operated when resting on its rear or side
