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.
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.
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.
