SAFETY SUMMARY ii
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 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.
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.
Do not operate the instrument in the presence of flammable gases or vapors, fumes, or finely-divided particulates.
The instrument is designed to be used in oice-type indoor environments. Do not operate the instrument
• In the presence of noxious, corrosive, or flammable fumes, gases, vapors, chemicals, or finely-divided
particulates.
• In relative humidity conditions outside the instrument’s specifications.
• In environments where there is a danger of any liquid being spilled on the instrument or where any liquid
can condense on the instrument.
• In air temperatures exceeding the specified operating temperatures.
• In atmospheric pressures outside the specified altitude limits or where the surrounding gas is not air.
• In environments with restricted cooling air flow, even if the air temperatures are within specifications.
• In direct sunlight.
