The following environmental requirements are provided to ensure proper
operation and long instrument life.
Operating Temperature
The

Oscilloscope can be operated where the ambient air temperature
is between
O
O and 40 °C and can be stored in ambient temperatures from
-55
°C to
+75
°C. After storage at temperatures outside the operating limits,
allow the instrument to stabilize at a safe operating temperature before
applying power.
Ventilation Requirements
The
