Handling the Test Leads and Cables
• Before turning the instrument on, make sure the power supply voltage matches
that indicated on the its power connector. Connection to an improper power
supply voltage may damage the instrument and present an electrical hazard.
• To avoid electrical accidents and to maintain the safety specifications of this
instrument, connect the power cord provided only to a 3-contact (two-conduc-
tor + ground) outlet.
To suppress noise, the instrument needs to be set to match the frequency of the
power source. Before operating, set the instrument to the frequency of your com-
mercial power. If the power supply frequency is not set properly, measurements
will be unstable.
See "2.5 Selecting the Line Frequency" (

p.20).
Make sure the power is turned off before connecting or disconnecting the power
cord.
• To avoid damage to the instrument, protect it from physical shock when trans-
porting and handling. Be especially careful to avoid physical shock from drop-
ping.
• Do not apply heavy downward pressure with the stand extended. The stand
could be damaged.
This instrument may cause interference if used in residential areas. Such use
must be avoided unless the user takes special measures to reduce electromag-
netic emissions to prevent interference to the reception of radio and television
broadcasts.
• To avoid breaking the test leads and cables, do not bend or pull them.
• Avoid stepping on or pinching cables, which could damage the cable insula-
tion.
