Tare function
By pressing the [TARA] button, the display will be set to "0". All
measurements from then on are displayed relative to the set tare value.
If the tare function is activated, the 'Tare' arrow will be displayed. To
deactivate, press and hold the [TARA] button for > 2 seconds.
⇒
By activating [TARA] the Min. and Max. memory will be deleted.
Zero point correction (for gauge pressure sensors)
When there is no pressure on the pressure ports, the instrument will display
a "0". However, if there is a permanent deviation (when operating in trouble-
free ambient conditions), there is a possibility to carry out a permanent zero
point correction.
In order to carry out a zero point correction, press the [TARA] button for
approx. 5 seconds. (Only possible if the display value deviates from the
factory calibration by less than 2 %, e.g. 0 ... 25 bar (0 ... 360 psi)
⇒
Zero point correction up to 0.5 bar (7.3 psi) possible.
