USER MANUAL NOVAplus
MRU GmbH, D-74172 Neckarsulm 8 / 95
1.3. Ensure safety
► Please read the user manual completely before the first use.
► Only use the analyzer for the intended use and within the parameters
specified in the technical data.
► Do not use any violence.
► Avoid falls.
► Do not put the analyzer into use, if the housing, power supply unit or
supply leads are damaged.
► Do not store the analyzer together with solvents. Do not use
desiccants.
► Only carry out maintenance and service work on this analyzer as de-
scribed in the User Manual. Observe the prescribed action steps.
► Operate the analyzer only in closed, dry rooms and protect it from
rain and moisture.
► When operating the analyzer on mains power, operate it only with
the mains adapter supplied
► The analyzer must not be located in the immediate vicinity of open
fire or great heat.
► Do not use the metal tube of the gas sampling probe or other metal-
lic parts / accessories as electrical conductors.
► Do not use the analyzer in or under water.
► The specified temperature range of the gas sampling probe must not
be exceeded, otherwise the probe tube and temperature sensor will
be destroyed.
► Moisture, being pumped out of the condensates trap can be slightly
acidic.
In case of skin contact IMMEDIATELY: clean affected parts of the
body. Avoid getting liquid in eyes. Please carefully clean all parts that
come into contact with the condensates.
► After measurement, vent the analyzer with ambient air and allow the
probe to cool. A hot probe could cause burns or ignite flammable
material.
► Electrochemical sensors are by their operating principle not only sen-
sitive to the gas they are intended for, but for other gases as well.
This cross sensitivity is compensated by MRU for the typical applica-
tion of flue gas analysis. However, unusual high concentration levels
of single gas components might lead to a reduced measurement ac-
curacy of other gas components and to a temporary change of the
sensitivity of sensors, which may require several hours recovery time.
Especially concentration levels as high as several % for single gas
components may affect the measurement of other gas components
at ppm level. Those applications need to be discussed with MRU in
detail
