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.
WARNING - Electrical Shock Hazard
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.
The oscilloscope should be positioned to allow easy access to the socket-
outlet. Disconnect the oscilloscope from the AC supply by unplugging the
instrument’s power cord from the AC outlet after the oscilloscope is placed
in Standby state.
CAUTION
The outer shells of the front panel BNC terminals (CH1, CH2, EXT TRIG)
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.
Avoid electrical shock hazard by unplugging the power cord from the AC
outlet before cleaning.
