Span setpoint
Check the span setpoint using function 22.
The displayed setpoint must agree with the calibration gas value. If this is not the case, make
them agree using function 22.
Select the leading measuring range for "Total calibration".
The setpoints must lie as far from the zero point as possible (at least 60% of the respective
full-scale value). Provide the corresponding calibration gases for the span calibration. Enter
the setpoints under function 22.
Changing measuring ranges
The linearized characteristic for the largest measuring range (according to the rating plate) is
stored in memory. If the largest measuring range (function 41) is changed, this full-scale
value must not be exceeded.
The measuring range must not fall below the smallest measuring range (according to the
rating plate), since in this case the noise and temperature influences on the measured value
will increase relative to the measuring range, which would impair repeatability and worsen
the drift behavior.
