Dimensions and Weight

Do not block the air intake at the front and side, or the exhaust at the rear of the instrument.
The front air inlet requires a minimum of 6 inches (15 cm) clearance. Inlet air temperature must be
l
within the temperature range of 20°C to 30°C.
The rear air outlet requires a minimum of 6 inches (15 cm) clearance.
l
The small air outlet on the left side of the unit must also be unrestricted, with a minimum clearance of
l
1.25 inches (30 mm) or more. Clearance to the instrument support rail could be as small as 10 mm if
rack mounted.
The instrument should not be installed in a pressured rack or enclosure.
