32 M8190A Getting Started Guide
4.3 Thermal Protection
Overheating Detection The instrument monitors its internal temperature. If the temperature exceeds
approximately 80°C the power supply is switched off. The instrument will not turn on
automatically if the temperature is decreasing again.
Fan Failure If a fan is broken or prevented from operating by a blockage the temperature will
increase. When the temperature exceeds approximately 80°C the overheating
detection switches off the instrument for safety reasons. For reliability, it is
recommended to send instruments with broken or defective fans immediately to
Keysight Service for repair.

The instrument is not designed for outdoor use. Do not expose the instrument to rain or
other excessive moisture. Protect the instrument from humidity and temperature
changes, which could cause condensation within the instrument.
Do not operate the instrument in the presence of flammable gases, fumes or powders.
Operation of any electrical instrument in such an environment constitutes a definite
safety hazard.
4.6 Cleaning Recommendation
To prevent electrical shock, disconnect the instrument from mains before cleaning. Use
a dry cloth or one slightly dampened with water to clean external case parts. Do not
attempt to clean internally.
