Getting Started Manual
WJ-A-GS-E Rev A 11
Power and Ground Connections
The instrument is provided with 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 connection. The AC inlet
ground terminal is connected directly to the
frame of the instrument. For adequate
protection against electrical shock hazard,
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 scope should be positioned to allow
easy access to the socket-outlet. To
completely remove power to the scope,
unplug the instrument’s power cord from the
AC outlet.
It is recommended that the power cord be
unplugged from the AC outlet if the scope is
not to be used for an extended period of
time.
CAUTION
The outer shells of the front panel
terminals (CH1, CH2, CH3, CH4, EXT)
are connected to the instrument’s
chassis and therefore to the safety
ground.
Calibration
The recommended calibration interval is one year. Calibration should be performed by
qualified personnel only.
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.
