5 Operation
5.1 Display elements
1: Main display
Display of current measuring value or of
minimal measured value (“Lo” blinking) or
maximal value (“Hi” blinking)
minimal measured value (“Lo” blinking) or
maximal value (“Hi” blinking)
LOBAT
Indicates low battery
5.2 Pushbuttons
on/off:
on/off switch, press key long to switch device off
mode:
press short: changes between actual measuring
value, the minimal measured value (“Lo” blinking) and
maximal measured (“Hi” blinking) value.
press >2s: reset Min and Max value
value, the minimal measured value (“Lo” blinking) and
maximal measured (“Hi” blinking) value.
press >2s: reset Min and Max value
zero:
press >2s:
activates / deactivates the “Zero-function“
6 Starting
Switch the device on with button
.
After the segment test
( )
the device displays some information to its current configuration:
, if offset correction is active
, if scale corrections active
Unit of meas. value: nbAr (=mbar) | nnHg (=mmHg)
, if sea-level correction is active
P.OFF, if auto power-off is active
Afterwards the device is ready for measuring.
Afterwards the device is ready for measuring.
7 Min-/max- value memory
Display MIN-value (Lo):
Press button mode shortly
Display changes between „Lo‟ and min-value
Display MAX-value (Hi):
Press mode shortly again
Display changes between „Hi‟ and max-value
Display actual value again: Press mode shortly again
Actual value is displayed
Delete MIN/MAX:
Press button mode for 2 s
MIN&MAX are deleted. „CLr‟ (Clear) is displayed
shortly
The Min-/max- display is automatically set to actual value display after 10 s.
The Min-/max- values are deleted if the device is switched on after it had been turned off.
The Min-/max- values are deleted if the device is switched on after it had been turned off.
8 Zero-function (relative measuring)
With help of the Zero-

“ NULL” is displayed shortly and the displayed value is set to 0. Press again “zero” for 2s to display
the absolute value again.
the absolute value again.
Note: Setting and resetting the Zero function will delete your min-/max- value memory.
Field of application: Over/ Under pressure measurement, please mind the measuring range!
9 General information on absolute pressure measurement
The device measures the absolute pressure. This must not be confused with the pressure at sea
level display by weather stations. There the pressure loss due to height above sea level is
deducted. The device is also able to perform this sea-level correction on the displayed air pressure.
Therefore
level display by weather stations. There the pressure loss due to height above sea level is
deducted. The device is also able to perform this sea-level correction on the displayed air pressure.
Therefore
(Sea Level correcti
on) has to be activated (= “on”) and the current height above
sea level (ALTI = Altitude in [m]) has to be entered at the configuration.
