To Calculate Total Measurement Error

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
• For dc voltage, dc current, and resistance measurements, you may need
• For ac voltage and ac current measurements, you may need to apply an

inaccuracies that result from the function and range you select, as well as
the input signal level. The reading error varies according to the input level
on the selected range. This error is expressed in percent of reading. The
