LeCroy WAVESURFER User Manual

WaveSurfer DSO
WS-OM-E Rev B 29
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 DSO, or
disconnection of the safety ground terminal
creates a hazardous situation.
Intentional interruption is prohibited.
The DSO should be positioned to allow easy
access to the socket-outlet. To completely remove
power to the DSO, unplug the instrument’s power
cord from the AC outlet after the DSO is placed in
Standby state.
In Standby state the DSO is still connected to the
AC supply. The instrument can only be placed in a
complete Power Off state by physically
disconnecting the power cord from the AC supply.
It is recommended that the power cord be
unplugged from the AC outlet if the DSO is not
being used for an extended period of time.
See On/Standby Switch for more information.
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.
On/Standby Switch
The front panel On/Standby switch controls the operational state of the DSO. This toggle switch is
activated by momentarily pressing and releasing it.
There are two basic DSO states: On or Standby. In the "On" state, the DSO, including its
computer subsystems (CPU, hard drive, etc,) is fully powered and operational. In the "Standby"
state, the DSO, including computer subsystems, is powered off with the exception of some
"housekeeping" circuitry (approximately 2 watts dissipation).
Always use the On/Standby switch to place the DSO in Standby state so that it executes a proper
shutdown process (including a Windows shutdown) to preserve settings before powering itself off.
This can be accomplished by pressing and holding in the On/Standby switch for approximately 5
seconds.
Note: To power off completely, place the DSO in Standby state, then disconnect the power cord.
