the FLOW display indication appears, which provides all relevant information of the
measurement.
Meaning of the display elements (FLOW):
o
Top left: Display of current operating mode (ZERO = zero setting, FLOW =
volume flow measurement operation, ERR = overload error)
o
In the upper middler: maximum measurement range (cannot be changed, size
according to model)
For some units the value 99.999 can be indicated, in case
the maximal possible pressure value exceeds an volume flow value >=
100.000.
o
Top right: physical unit
o
In the middle: current volume flow measurement value (calculated from
measurement value of the internal pressure sensor).
o
Bottom left: Rechargeable battery charger display (at mains operation: plug
symbol)
Example
(compare illustration):
- Operating mode volume flow (FLOW)
- Maximal volume flow = 40828 l/s
- Current measurement value = 0 m/s
- Tightness = 1,2 kg/m

- mains operation (bottom left)
Protection against overload:
IMPORTANT: Please bear in mind that the connected pressure does not exceed
125% of the measurement range of the Pneumator. If this happens slowly, the
internal magnetic valve will lock at this value and ERR appears in the display. Make
sure that the high pressure is no longer present and unlock the equipment by
pushing the button OK.
ATTENTION:If an overload occurs too quickly (approx. <1ms), the pressure sensor
can be destroyed.
Manual zero balance (ZERO)
In case the reference measurement element has to be set to zero during the
measuring procedure, please press the button ZERO. After approx. 3-5 seconds the
measurement operation will proceed again.
