8.2.7.1
Calibration: AUTOCAL/drift values: Drift values
This function is used to display the drift values of the zero point and sensitivity, and to
change them if necessary. The drift values are the total of the deviations in measured values
for the zero and sensitivity calibrations. This parameter is specific to the component.
This menu display appears following selection of the drift va
l-
ues and allows selection of the desired component.
You can switch between the individual components by pres
s-
ing an arrow key. You can select the displayed component
using the <ENTER> key.
You can now view the dri
ft values and reset them if neces
sary.
To do this, position the cursor on the 4th line (reset) of the
display and press the <ENTER
> key.
