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.
1-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).
