Environment
2 10
The following environmental requirements are provided to ensure proper
operation and long instrument life.

Operating Temperature

The TDS 520A, 524A, 540A, & 544A Digitizing Oscilloscopes can be operated
where the ambient air temperature is between +4_ (0_ without the floppy
disk) and +50_ C and can be stored in ambient temperatures from -22_
(-40_ without the floppy disk) to +60_ C. After storage at temperatures
outside the operating limits, allow the chassis to stabilize at a safe operating
temperature before applying power.

Ventilation Requirements

The TDS 520A, 524A, 540A, & 544A Digitizing Oscilloscopes are cooled by
air drawn in and exhausted through its cabinet side panels by an internal fan.
To ensure proper cooling of the instrument, allow at least two inches
clearance on both sides and 3/4 inch on the bottom of the Digitizing
Oscilloscopes. (The feet on the bottom of the oscilloscope provide the
required clearance when set on flat surfaces.) The top of the oscilloscope
does not require ventilation clearance.
If air flow is restricted, the Digitizing Oscilloscopess power supply
may temporarily shut down.
