Understanding the " % of range " Error
The range error compensates for
inaccuracies that result from the function and range you select. The range
error contributes a constant error, expressed as a percent of range,
independent of the input signal level. The following table shows the range
error applied to the multimeter's 24
–
hour dc voltage specification.
Total Measurement Error
To compute the total measurement error, add the
reading error and range error. You can then convert the total
measurement error to a "percent of input" error or a "ppm
(parts
–
per
–
million) of input" error as shown below.
Error Example
Assume that a 5 VDC signal is input to the multimeter on
the
10 V
range. Compute the total measurement error using the 90
–
day
accuracy specifications: ± (0.0020% of r 0.0005% of range).
Reading Error = 0.0020% x 5 VDC = 100
