Measurement
6.1.
Preparation of each measurement
Power supply
The analyzer can be operated with an internal battery to warm up the instru-
ment or to use internal instrument functions. A mains connection is required
for the measurement including heated gas sampling probe and heating
hose.
Charging state of the battery
The battery symbol in the display indicates approximately the remaining ca-
pacity of the battery.
From 2% remaining capacity, the charging indicator starts to flash red. If the
instrument is not connected to the mains power supply within one minute,
the analyzer switches off to prevent battery discharge.
Even when the battery is discharged, the instrument can be operated com-
pletely on the power supply.
CAUTION
Acid from the condensate
Acid burns may result from weakly acidic liquids from the condensate.
►
If you come into contact with acid, wash the area immediately using a
lot of water.
DANGER
Risk due to toxic gases
There is a risk of poisoning.
Noxious gases are sucked in by the measuring device and released into
the ambient air.
►
Only use the measuring device in well ventilated spaces.
Connections to the instrument
►
Connect the gas sampling probe to the instrument (gas plug and electri-
cal plug).
►
Consider to connect a hose or collecting container if necessary to the con-
densate outlet when appropriate.
►
The hose and any connected reservoir connected to the outlet must not
be closed against ambient or include an air outlet to avoid overpressure.
►
Please note that measuring gas may leak at the instrument side or at the
VENT outlet. Connect a pump to the VENT output to collect the sample
gas. If an “active VENT” option is installed, an internal gas pump feeds the
sample gas completely to the VENT outlet, where an evacuating gas hose
should be connected.
►
In the case the option active vent is installed, note that the sample gas at
the exit may be diluted with ambient air and is therefore not adequate to
be reused in the process.
►
Ensure that ambient fresh air can be sucked in at the fresh air inlet. Con-
sider to connect a hose leading to fresh ambient air, when the instru-
ment’s environment contains toxic gases or a high CO
2
level.
