4.1 Operating modes (ModE)
The unit provides three selectable operating modes for flow measurement:
Operating
mode
Medium
Display unit
REL
Liquids, air
% (of the taught range) → 10.2.8
LIQU
Liquids
m/s, l/min, m3/h (fps, gpm, cfm)
GAS
Air
m/s, l/min, m3/h (fps, gpm, cfm)
The selected operating mode has no effect on the temperature measure-
ment, only absolute values in °C or °F are indicated.
The parameter settings are saved in the respective operating mode, i�e�
when the operating mode is changed, the settings are not lost�
If the operating modes LIQU and GAS are selected:
► Define the medium and the internal pipe diameter (→ 10.2.1).
► If required, calibrate curve of measured values (→ 10.4.9).
4.2 Select the medium (MEdI)
The unit has characteristic curves for different media� Depending on the operating
mode, the following media can be selected in the menu (→ 10.4.3):
Operating mode
Medium
REL LIQU GAS
*OIL1:
viscosity ≥ 40 mm²/s at 40 °C / ≥ 40 cSt at 104 °F
**OIL2:
viscosity ≤ 40 mm²/s at 40 °C / ≤ 40 cSt at 104 °F

4.3 Define the internal pipe diameter (diA)
In the operating modes LIQU and GAS the internal pipe diameter has to be
entered to define the volumetric flow (→ 10.2.2)
