Application Field
The ecom-UNO is suitable for the
measurement of overpressure, low
pressure and differential pressure of
gases. It is especially suitable for works
at heating, ventilation and air-conditioning
systems.
The measurement range covers pressures
from -200 up to +200 hPa. Never use the
ecom-UNO to measure higher pressure
values!
Pressures higher than the
indicated overload
will destroy the sensor !
Battery Change
Both 1,5 V AA (Mignon) batteries must
be replaced when the capacity indication
blinks (no point anymore).
Change the batteries as follows:
- Open the battery compartment cover
while slipping at the marked position.
- Extract used batteries and replace with
batteries of similar size (observe
polarity!).
Dispose used batteries
by specialized
collecting points!
- Close the battery compartment while
slipping the cover back.

Magnetic Fixation
The ecom-UNO is equipped with a fixing
magnet providing with a secure
positioning on most metal surfaces.
The magnetic field can
influence on the
function of heart
pacemakers!
Initiation
- Connect the tubings.
- Press the ON/OFF key.
3
- The ecom-UNO starts in the lower
measurement range and after 3 seconds
the instrument is ready for operation.
Auto-Off-Function
The ecom-UNO switches off automatically
after 5 minutes (by values up to 1 hPa/
mbar) respectively after 15 minutes (by
values higher 1 hPa/mbar).
4
Range Switch
By pressure beyond 20 hPa/mbar, the
ecom-UNO automatically switches over to
the higher range (resolution 0,01 hPa/
mbar -> resolution 0,1 hPa/mbar).
Range Exceeding
By exceeding of the measurement range
from -200 until +200 hPa four dashes are
displayed.
- Press ADJUSTMENT key.

moves from unit to unit.
- Release ADJUSTMENT key once the
desired unit is achieved.

HOLD / MIN /MAX
- Press HOLD key.
- Measurement values are „frozen" (value
sampled by pressing the key is indicated).
- Press again HOLD key.
- Min-value (lowest value since instrument
switch on) is indicated.
- Press again HOLD key.
- Max-value (highest value since instrument
switch on) is displayed.
- Press again HOLD key.
- The ecom-UNO is back to the
measurement mode.
- Keep HOLD key pressed.
- Min- and Max- values are erased.
