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.
Electrical Power
This instrument is intended to be powered from a CATEGORY II mains power environment. The mains
power should be 120 V RMS or 240 V RMS. Use only the power cord supplied with the instrument and
ensure it is appropriate for your country of use.
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
