Electrical Power
This instrument is intended to be powered from a CATEGORY II mains power environment. The mains
power should be 115 V RMS or 230 V RMS. Use only the power cord supplied with the instrument and
ensure it is appropriate for your country of use.
Do not use this instrument in an electrical environment with a
higher category rating than what is specified in this manual for this
instrument.
You must ensure that each accessory you use with this instrument
has a category rating equal to or higher than the instrument's
category rating to maintain the instrument's category rating. Failure
to do so will lower the category rating of the measuring system.
Ground the Instrument
To minimize shock hazard, the instrument chassis and cabinet must
be connected to an electrical safety ground. This instrument is
grounded through the ground conductor of the supplied, three-
conductor AC line power cable. The power cable must be plugged
into an approved three-conductor electrical outlet. The power jack
and mating plug of the power cable meet IEC safety standards.
Do not alter or defeat the ground connection. Without the safety
ground connection, all accessible conductive parts (including
control knobs) may provide an electric shock. Failure to use a
properly-grounded approved outlet and the recommended three-
conductor AC line power cable may result in injury or death.
Unless otherwise stated, a ground connection on the instrument's
front or rear panel is for a reference of potential only and is not
to be used as a safety ground. Do not operate in an explosive or
flammable atmosphere.
