Calibration
R71MD models offer three calibration methods:
Zero Calibration, Span Calibration and Linearity Calibration.
R71MHD models offer 5 calibration methods:
Zero Calibration, Span Calibration, Linearity Calibration, Internal Calibration and
Automatic Calibration.
Do not disturb the scale during any calibration.

5.3.2
Zero Calibration
Use this calibration method to adjust the zero calibration point, without affecting the span or linearity
calibration.
5.3.3
Span Calibration
Span calibration uses two calibration points, one at zero load and the other can be chosen by the user by
using the numerical keypad.
With the scale turned ON and no load on the pan, start Span Calibration to initiate the
procedure. Additional calibration values to be used are shown on the display. The best
accuracy is achieved using the mass closest to the full span value.
