As an example the steps needed to change the unit from bar to PSI are shown below.
6.3.2 Correcting the Zero Point (tlr)
You can correct the zero point by up to ±20% of the measuring range with the "teach lower
range" menue item (tlr). When the menue item is selected the entry points to "-rEt-".
To trigger the function go to "YES" with one of the arrow buttons and confirm with the mid-
dle button. This extra step prevents any unintentional zero shift while navigating the
menue.
With the final confirmation, the applied pressure is stored as zero point. "donE" appears on
the display to confirm that the zero point has been adjusted and the device switches back
to the menue item "Teach Lower Range" " (tlr).
Display
The steps needed to adjust the zero point are shown below (starting from display mode).
