by condensation is expected.
IP Rating
IP20 (as defined in IEC 60529).
2.4 Cooling Requirements
This 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) on each side of the scope. To
ensure adequate ventilation it is required to leave a 15 cm (6 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.
2.5 Power and Grounding Requirements
The instrument operates with a single-phase, 100 to 240 Vrms (+/-10%) AC power at 50/60 Hz (+/-
5%), or single-phase 100 to 120 Vrms (+/-10%) AC power at 400 Hz (+/-5%).
No manual voltage selection is required because the instrument automatically adapts to line voltage.
Depending on the type and number of options and accessories (probes, PC port plug-in, etc.), the
instrument can consume up to 380 W of power for the 8-channel models and 193 W for the 4-channel
models.
The instrument automatically adapts to the AC line input within the following ranges:
Voltage Range:
90 - 264 Vrms
90 - 132 Vrms
Frequency Range:
47 - 63 Hz
380 - 420 Hz
The instrument includes a grounded cord set containing a molded three-terminal polarized plug and a
standard IEC320 (Type C13) connector for making line voltage and safety ground connections. The
AC inlet ground terminal is connected directly to the frame of the instrument. For adequate protection
against electrical shock hazards, the power cord plug must be inserted into a mating AC outlet
containing a safety ground contact. Use only the power cord specified for this instrument and certified
for the country of use.
Warning: Electrical Shock Hazard!
Any interruption of the protective conductor inside or outside of the
scope, or disconnection of the safety ground terminal creates a
hazardous situation.
Intentional interruption is prohibited.

The position of the oscilloscope should allow easy access to the socket. To make the oscilloscope
completely power off, unplug the instrument power cord from the AC socket.
The power cord should be unplugged from the AC outlet if the scope is not to be used for an extended
period.
CAUTION: The outer shells of the front panel terminals (C1~C8, EXT) are
connected to the instrument’s chassis and therefore to the safety ground.
2.6 Cleaning
Clean only the exterior of the instrument, using a damp, soft cloth. Do not use chemicals or abrasive
elements. Under no circumstances allow moisture to penetrate the instrument. To avoid electrical
shock, unplug the power cord from the AC outlet before cleaning.
Warning: Electrical Shock Hazard!
No operator serviceable parts inside. Do not remove covers.
Refer servicing to qualified personnel
2.7 Abnormal Conditions
Do not operate the scope if there is any visible sign of damage or has been subjected to severe
transport stresses.
If you suspect the scope’s protection has been impaired, disconnect the power cord and secure the
instrument against any unintended operation.
Proper use of the instrument depends on the careful reading of all instructions and labels.
