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).
