Accuracy

We dene measurement tolerances in terms of f.s. (full scale), rdg. (reading) and dgt. (digit) values with the

following meanings:

f.s. (maximum display value/range)

The maximum displayable value. This is usually the name of the currently selected range.

rdg. (displayed value)

The value currently being measured and displayed on the measuring instrument.

dgt. (resolution)

The smallest displayable unit on a digital measuring instrument, i.e., the input value that causes

the digital display to show a “1” as the least-signicant digit.

Usage Notes

Follow these precautions to ensure safe operation and to obtain the full benets of the various

functions. Read the separate document “Operating Precautions” carefully before using the

instrument. Ensure that your use of the product falls within the specications not only of the

instrument itself, but also of any accessories, options, batteries, and other equipment being

used.

DANGER

•To prevent an electric shock, do not touch any areas beyond the barrier

while the instrument is in use.

See: "1.2 Part Names" (p.12)

•The maximum measurement current varies with the frequency, and the

current that can be measured continuously is limited. Operating the

instrument at less than this limitation is referred to as derating. Do not

measure currents in excess of the derating curve. Doing so may result in

instrument damage or malfunction, a re, or burn due to sensor heating.

•To prevent an electric shock, conrm that the white portion (insulation layer)

inside the cable is not exposed. If a color inside the cable is exposed, do not

use the cable.
