To avoid Fire or Personal Injury:
• Use Proper Power Cord. Use only the power cord supplied with the product
and certified to use in your country.
• Connect or Disconnect Correctly. When the probe or test lead is connected
to a voltage source, please do not connect and disconnect the probe or test
lead.
• Product Grounded. This instrument is grounded through the power cord
grounding conductor. To avoid electric shock, the grounding conductor
must be grounded. The product must be grounded properly before any
connection with its input or output terminals.
When the instrument is powered by C, do not measure C power sources
directly otherwise it will cause a short circuit. This is because the testing
ground and power cord ground conductor are connected.
• Check all Terminal Ratings. To avoid fire or shock hazard, check all ratings
and markings on this product. Refer to the user manual for more
information about ratings before connecting to the instrument.
• Do not operate without covers. Do not operate the instrument with covers
or panels removed.
• Use the Proper Fuse. Use only the specified type and rating fuse for this
instrument.
• void exposed circuit. Be careful when working on exposed circuitry to
avoid risk of electric shock or other injury.
• Do not operate if any damage. If you suspect damage to the instrument,
have it inspected by qualified service personnel before further use.
• Use your Oscilloscope in a well-ventilated area. Make sure the instrument
installed with proper ventilation.
• Do not operate in damp conditions.
• Do not operate in an explosive atmosphere.
• Keep product surfaces clean and dry.
