Cooling fans
This instrument contains one or more cooling fans. For continued safe operation of the instrument,
the air inlet and exhaust openings for these fans must not be blocked nor must accumulated dust
or other debris be allowed to reduce air flow. Maintain at least 25 mm clearance around the sides
of the instrument that contain air inlet and exhaust ports. If mounted in a rack, position power
devices in the rack above the instrument to minimize instrument heating while rack mounted. Do
not continue to operate the instrument if you cannot verify the fan is operating (note some fans
may have intermittent duty cycles). Do not insert any object into the fan's inlet or outlet.
For continued safe use of the instrument
• Do not place heavy objects on the instrument.
• Do not obstruct cooling air flow to the instrument.
• Do not place a hot soldering iron on the instrument.
• Do not pull the instrument with the power cord, connected probe, or connected test lead.
• Do not move the instrument when a probe is connected to a circuit being tested.
