To Calculate Total Measurement Error
The multimeter's accuracy specifications are expressed in the form:
(% of reading + count)
In addition to the reading error and count 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.
