temporary conductivity caused by 
condensation must be expected. 
 
Protection Class 1 refers to a grounded 
equipment, in which protection against 
electric shock is achieved by Basic 
Insulation and by means of a connection to 
the protective ground conductor in the 
building wiring. 
Cooling Requirements
The instrument relies on forced air cooling 
with internal fans and ventilation openings. 
Care must be taken to avoid restricting the 
airflow around the apertures (fan holes) at 
each side of the scope. To ensure adequate 
ventilation it is required to leave a10 cm (4 
inch) minimum gap around the sides of the 
instrument. 
CAUTION
Do not block the ventilation holes 
located on both sides of the scope. 
CAUTION
Do not allow any foreign matter to enter 
the scope through the ventilation holes, 
etc. 
AC Power Source
The instrument operates from a single-
phase, 100 to 240 V
rms
(+/-10%) AC power
source at 50/60 Hz (+/-5%), or single-phase 
100 to 120 V
rms
(+/-10%) AC power source at
400 Hz (+/-5%).
No manual voltage selection is required 
because the instrument automatically adapts 
to line voltage. 
Depending on the accessories installed (PC 
port plug-ins, Ethernet & GPIB options, etc.), 
the instrument can draw up to 75 W (75 VA). 
Note:
The instrument automatically adapts 
itself to the AC line input within the 
following ranges: 
Voltage 
Range: 
90 to 264 V
rms
90 to 132 V
rms
Frequency 
Range: 
47 to 63 Hz
380 to 420 Hz
