X-Stream Operator’s Manual
WM-OM-E Rev I 49
The scope’s factory settings result in only two basic scope states: On (LED Green) or Standby
(LED Off). In this case of Standby (LED Off), the scope is powered off with the exception of some
“housekeeping” circuitry (approximately 12 watts dissipation). The scope can only be placed in a
complete power off state by unplugging the instrument’s power cord from the primary power source
(AC outlet). It is recommended that the power cord be unplugged from the AC outlet if the scope is
not being used for an extended period of time.
You have the ability to change the scope original factory settings via the “Power Options
Properties” menu in Windows by following the path: Settings Power Options. It is important to note
that the Windows Power Option named “Standby” provides control of only the scope’s computer
subsystems (CPU, hard drive, etc.) and does not affect the other subsystems within the scope. In
general, these other subsystems remain fully powered. For additional information on setting these
Power Options, see the Windows Help menu or other related technical documentation. In terms of
control buttons, this scope uses only a power button/switch and therefore references to a sleep
button are not applicable.
The scope can always be placed in the Standby state (LED Off) Power Off (except for some
“housekeeping” circuits) by pressing and holding in the Standby toggle switch for approximately 5
seconds.
Fuse Replacement
Set the scope’s Standby (power) switch to Standby mode
(LED off) and disconnect the power cord before
inspecting or replacing the fuse. Open the black fuse
holder (located at the rear of the instrument directly to the
right of the AC inlet) using a small, flat-bladed
screwdriver. Remove the old fuse, replace it with a new
5x20 mm “T” rated 10.0 A/250 V fuse, and reinstall the
fuse holder.
WARNING
For continued fire protection at all
line voltages, replace fuse with the
specified type and rating only.
Disconnect the power cord before
replacing fuse.
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.
