5 Specifications
Accuracy Specifications
Transfer Accuracy
Transfer accuracy refers to the error introduced by the multimeter due to
noise and short
–
term drift. This error becomes apparent when comparing
two nearly
–
equal signals for the purpose of "transferring" the known
accuracy of one device to the other.
24
–
Hour Accuracy
The 24
–
hour accuracy specification indicates the multimeter's relative
accuracy over its full measurement range for short time intervals and
within a stable environment. Short
–
term accuracy is usually specified for a
24
–
hour period and for a ±1 °C temperature range.
90
–
Day and 1
–
Year Accuracy
These long
–
term accuracy specifications are valid for a 23 °C ± 5 °C
temperature range. These specifications include the initial calibration
errors plus the multimeter's long
–
term drift errors.
Temperature Coefficients
Accuracy is usually specified for a 23 °C ± 5 °C temperature range. This
is a common temperature range for many operating environments. You
must add additional temperature coefficient errors to the accuracy
specification if you are operating the multimeter outside a 23 °C ± 5 °C
temperature range (the specification is per °C).
