LabMaster 10 Zi Oscilloscopes
against electrical shock hazard, the power cord plug must be inserted
into a mating AC outlet containing a safety ground contact.
WARNING Only use the power cord provided with your
instrument. Any interruption of the protective conductor inside or
outside of the oscilloscope, or disconnection of the safety ground
terminal creates a hazardous situation. Intentional interruption is
prohibited.
In Standby mode, the oscilloscope is still connected to the AC supply.
The instrument can only be placed in a complete Power Off state by
removing the power cord.
CAUTION Do not place the instrument so that it is difficult to
reach the power cord inlet to disconnect the instrument.
CAUTION Always use the Power Switch or File → Shutdown
command in the software to properly shut down your instrument.
Never substitute this practice by pulling the instrument power cord
from the socket or shutting down a connected power strip.
Standby (Power) Switch and Oscilloscope
Operational States
For the MCM-Zi Master Control Module, the Standby (Power) switch
controls the operational state of the oscilloscope. This toggle switch is
activated by momentarily pressing and releasing it.
The oscilloscope's factory settings result in only two basic oscilloscope
states: On or Standby. In the case of Standby, the oscilloscope is
powered off with the exception of some housekeeping circuitry. The
oscilloscope can only be placed in a complete power off state by
unplugging the power cord from the primary power source (AC outlet).
It is recommended that the power cord be unplugged from the AC
outlet if the oscilloscope is not being used for an extended period of
time.
