• The maximum rated voltage between input terminals
and ground is 600 V DC/AC (CAT III). Attempting to
measure voltages exceeding 600 V DC/AC with
respect to ground could damage the instrument and
result in personal injury.
• 1000 V or 600 V may be labeled depending on the
supplied test leads, but this is the rating of the test lead
and not the rating performance of this instrument.
Please refer to the Specifications for the rating
performance of this instrument.
• Before attaching to or removing the test lead from the
instrument, please remove the Test Lead from the
tested objected and turn the rotary selector to OFF.
• Test leads should only be connected to the secondary
side of a breaker, so the breaker can prevent an
accident if a short circuit occurs. Connections should
never be made to the primary side of a breaker,
because unrestricted current flow could cause a
serious accident if a short circuit occurs.
• Persons wearing electronic medical devices such as a
pacemaker should not use the 9804-02 Magnetic
Adapter with magnet (option). Such persons should
avoid even proximity to the 9804-02, as it may be
dangerous. Medical device operation could be
compromised, presenting a hazard to human life.
Please only use batteries for electrical supply. Any other
electrical supply may damage the instrument and tested
object and cause electric shock.
