4. Analyzer start up
The portable analyzer is switched on at
the “ON” button (Push for 2 seconds).
At the same time an air pump is switched on. This pump is responsible for the suction of
the gas sample.
For a reliable measurement, please observe the minimum warm-up time in the
lower right corner of the display until the word
“READY” is displayed in the lower left corner
Since the analyzer sucks in the gas sample autonomously, do not insert gas under pressure into the
analyzer. The gas sample must not contain any water at all.
To protect the sensors a dust/dirt/moisture filter is included in the delivery.
A new hydrophobic filter can be ordered separately, see Table 2: Spare parts.
After warming up the screen will display the current O

and/or CO

measurement:

Never work with the analyzer without this hydrophobic filter.
The analyzer has to be recharged with the battery charger included in the
delivery. Take care that the built-in battery is always completely recharged.
Charge battery only at a temperature higher than 5 °C.
During a long time of inactivity, charge battery onto 40% and recharge it to
this level every 2 to 3 months. This avoids a deep discharge of the battery
which could lead to a breakdown of the battery.
