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 (part-per- million) of input” error as shown below.
% of input error
=
ppm of input error

Error Example
Assume that a 5Vdc signal is input to the multimeter on the 10 Vdc 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 5Vdc
=
100
V
Range error
= 0.0005% x 10Vdc
=
50
V
Total error
= 100
V + 50
V
=
150
V
=
0.0030% of 5Vdc
=
30 ppm of 5Vdc
