6.4.1 Pressure units (unit)

Depending on the measuring range of the current pressure sensor, the pressure value
can be displayed in any one of the following units: mbar, bar, Pa, kPa, MPa, mmHg, inHg
or psi.

6.4.2 Sea-level (SL) and altitude (Alti) correction for absolute pressure sensor

With a connected absolute pressure sensor, the instrument measures absolute pressure.
This is not to be confused with the "air pressure at sea level" given by the weather station.
With this pressure indication, the altitude-dependent atmospheric pressure drop is
calculated. The instrument is capable of making this air pressure altitude correction.
Setting of "SL" and "Alti"
1. Press the [SET/MENU] button for 2 seconds.
⇒
The main menu "SEt" is accessed.
2. With the [TARA] button, select the "SL" parameters.
3. With the [MIN] or [MAX] buttons, activate the "SL" parameter.
4. With the [STORE/QUIT] button, confirm the entry.
5. With the [TARA] button, select the "Alti" parameters.
6. With the [MIN] or [MAX] buttons, enter the altitude.
7. With the [STORE/QUIT] button, confirm the entry.
8. Press the [SET/MENU] button.
⇒
Return to main menu.
The setting is only possible, if an absolute pressure sensor is connected to
sensor connection 1.
When the "Sea Level" function is activated, the arrow for 'SL' is indicated below in the
display. Once the altitude of the fixed location above sea level has been entered, the
instrument displays the absolute pressure at sea level.
