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.

Year Accuracy
These long
–
term accuracy specifications are valid at the calibration
temperature (T
cal
) ± 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 at the calibration temperature (T
cal
) ± 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 the ± 5 °C temperature range (the specification is per °C).
