Operating Precautions
8
Handling the Instrument
• Do not allow the instrument to get wet, and do not take measurements with wet
hands. This may cause an electric shock.
• Do not attempt to modify, disassemble or repair the instrument; as fire, electric
shock and injury could result.
To avoid damage to the instrument, protect it from physical shock when transporting and
handling. Be especially careful to avoid physical shock from dropping.
This instrument may cause interference if used in residential areas. Such use must be
avoided unless the user takes special measures to reduce electromagnetic emissions to pre-
vent interference to the reception of radio and television broadcasts.
Handling the Cords and Probes
• Avoid stepping on or pinching cables, which could damage the cable insulation.
• To avoid breaking the cables, do not bend or pull them.
• To avoid damaging the power cord, grasp the plug, not the cord, when unplugging it from
the power outlet.
• When disconnecting the BNC connector, be sure to release the lock before pulling off the
connector. Forcibly pulling the connector without releasing the lock, or pulling on the cable,
can damage the connector (p. 23).
• Use only the specified connection cables. Using a non-specified cable may result in incor-
rect measurements due to poor connection or other reasons.
• Before using a test fixture, read the instructions provided with it.
Before Turning Power On
Before turning the instrument on, make sure the supply voltage matches that indi-
cated on its power connector. Connection to an improper supply voltage may damage
the instrument and present an electrical hazard.
