Precision is defined as the combined effect of linearity, repeatability, and hysteresis throughout the
operating temperature range. Some manufacturers use the word “Accuracy” in place of “Precision”,
however the meaning is identical.
2
Zero drift typically improves with sensor age.

Requires Additional Uncertainty when operating in gauge mode 7050 or 7050i in the absolute mode. This
uncertainty component would be combined RSS with the gauge mode uncertainty of the instrument.
