7.12.8.1 Calculating SPAN value
SPAN indicates the equivalent input voltage in mV/V related to the maximum load (Max)
of the scale.
It is calculated as follows:
* load cell sensitivity C
n
= rated output C
n
(see technical data of the load cell)
The input voltage in mV/V equivalent to the dead load can be calculated by using the
dead load rather than the maximum load using the formula specified earlier.
Normally, calculation of the dead load (scale without load/empty hopper) is not
necessary.
Subsequent dead load correction (as described in Chapter 7.12.8.1 ) can be used for later
re-determination of the dead load, when the scale/hopper is empty.
4. Confirm the entries.
Weight value, weight unit and measuring signal in mV/V corresponding to this
value are displayed in the line [Calibrated at].
The verification is displayed by "Setting Span mV/V ".
