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%).
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 400 W.
The instrument automatically adapts to the AC line input within the following ranges:
Voltage Range:
90 - 264 Vrms
Frequency Range:
47 - 63 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~C4, EXT) are connected
to the instrument’s chassis and therefore to the safety ground.
