To Calculate Total Measurement Error

142
The multimeter's accuracy specifications are expressed in the
form:
( % of reading + % of range ). In addition to the reading
error and range error, you may need to add additional
errors for certain operating conditions. Check the list below
to make sure you include all measurement errors for a given
function. Also, make sure you apply the conditions as
described in the footnotes on the specification pages.
• If you are operating the multimeter outside the
temperature range specified, apply an additional
temperature coefficient error.
• For AC voltage and AC current measurements, you may
need to apply an additional low frequency error or crest
factor error.
