Notes:
(1)
Precision is defined as the combined effects of linearity, repeatability and
hysteresis.
(2) Expression of accuracy (uncertainty) conforms with the recommendation of the
ISO Guide to the Expression of Uncertainty in Measurement and includes RSS of
precision, stability, temperature effects, and the calibration standard to 2 sigma
(95%). The expanded uncertainty in the standards utilized by RUSKA to calibrate
the LEM is typically 0.1
