Automatic
calibration
(AutoCal TEC,
AutoCal DIN)
Here you can cancel the calibration procedure with <M>. This corresponds to a
single-point calibration. The value of the zero point (ASY) is displayed. Pressing
<ENTER> displays the value of the slope (SLO).
Here you can cancel the calibration procedure with <M>. This corresponds to a
two-point calibration. The value of the zero point (ASY) is displayed. Pressing
<ENTER> displays the value of the slope (SLO).
