In general, if your location is between the 45th parallel and the equator, gravity correction is
greater than 1.0. For example, you add 1.0006 for an error that is .06% because gravity is
less at these latitudes. For locations between the 45th parallel and the North or South Pole,
your correction factor is less than 1.0 (for example, .9994 for an error that is -.06%).
Gravity Correction compensates for an object weighing less at the equator than at the North
or South Pole. This allows you to enter the correction factory for your location and apply it to
your C2 calibration. This is not used for the hard calibration.

5.2.11 Tare Weight
Tare weight is the amount of weight tared off with the last tare command or the amount you
entered. The tare weight equals the difference between the net and gross weight readings.
