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).
