16 STARTING UP
W A R N I N G !
False supply voltage can damage the equipment. When connec t-
ing the equipment, please ensure that the supply voltage is
identical with the information provided on the model type plate!

Check electrical connections and gas connections.

Switch on mains voltage.
 Turn measuring range selection switch from „0“ to the desired measuring range. The
analyser is ready for operation immediately.
C A U T I O N !
If during transport the analyser was exposed to extreme
changes of temperature, an adequate time for temperature ada p-
tion has to be observed, to prevent condensation in the device.
16.1 EXECUTION WITH RECHARGEABLE BATTERY
Check charge condition of the battery. For that purpose actuate the push-
button „battery check“
at the rear side of the device. The digital indication has to show a value of min. 83. Ist der Wert
geringer, muss der Akku aufgeladen werden. For this connect the low heat device connector of
the provided connection cable at the rear side with the low heat device socket and the earthing
type plug with the mains power
. In position “0” of the measuring range selector switch the battery
is charged in approximately 14 hours.
N O T E !
Never fully discharge the battery (battery check indication < 83),
hereby the life time is reduced.
The analyser with battery also can be operated alwaysat the mains.
17 CALIBRATION
The accuracy of an analyser mainly is dependent on its calibration.
N O T E !
Before calibration it has to be assured that the calibration condi-
tions correspond to the conditions during measurement. The
flow rate, the ambient temperature and the barometric pressure
conditions have to be constant. Under this terms a calibration of
the analyser is necessary aproximately one time a week to main-
tain the accuracy. If flow rate, ambient temperature or barome-
tric pressure conditions are changing significantly, a new cal i-
bration is necessary.
During calibration the device must not be exposed to vibrations.
For zero calibration of the analyser an oxygen-free gas, mostly nitrogen (N
2
5.0) is used.
