3.2 Factory default curve
The commands described in this section are used to set up the factory default curve:
D Adjusting the default curve: SZA
, SFA
D Gravitational acceleration correction: ACA, ACU
Setting the characteristic curve
The WE works initially with a factory default curve SZA
, SFA. This factory default calibration
is made with a calibration standard for 0mV/V and 2mV/V (=200000 internal digits). This
factory default curve should not be modified.
A second characteristic curve (LDW
, LWT) is available for the scale adjustment.
The gravitational acceleration correction is then activated via command ACA and ACU, if the
place where the scale was adjusted is not the same as the place of installation and the
gravitational acceleration factors are different.
Setting the factory default curve with SZA
, SFA (absolute value calibration in mV/V)
