6.3 Important device se ngs for calibraon using mode CALBRATING
Calibraon date
The calibrator has an integral real-me clock with date. The current date of a calibraon is (with
oponal
soware stated later in the calibraon cerficate. Before starng a
calibraon, you must ensure that the internal date of the ist correct (see chapter
7.4.5 „ addional menu opons: -Configuraon“).

6.4 Pressure unit and resoluon
Aer selecng one of the main menu items (e.g. , or - )
from the menu (press key), using the menu opon „Unit“, and its associated
submenu respecvely (move the cursor to „Unit“ and press the right or le arrow key), you can set
the unit and adjust its resoluon (see chapter 7.3 „Operang modes“).

6.5 Zero point and/or Offset correcon
Zero adjustment for overpressure (gauge) instruments
If the measured value shown on the , with a posive/relave reference
pressure sensor connected and the test assembly vented to atmosphere, is not equal to zero, then
by pressing the
key twice (within five seconds), the zero point can be corrected (maximum
allowable correcon value is twice the magnitude of the accuracy class).
