Electrical characteristics
AUTOCAL function Automatic calibration (adjustment) of all channels with ambient air (in case
oxygen is present as measured component) or nitrogen (depending on
measured component), adjustable cycle time from 1 … 24 hours. If 0 hours
is entered, the cycle is deactivated.
AUTOCAL cycle must be activated for certied emission measurements
Options Add-on electronics, with 8 additional digital inputs and 8 additional relay
outputs, for e.g. triggering of automatic calibration, PROFIBUS PA/DP
Climatic conditions
Permissible ambient temperature
• During operation
• During transportation and storage
+5 ... +45 °C (+41 ... +113 °F) (limited when used with H
2
S sensor,
cf. Hydrogen sulde sensor (Page 41))
-20 °C ... + 60 °C (-4 ... +140 °F)
Permissible ambient humidity < 90% RH (relative humidity) during transportation and storage (Delivery
information (Page 12))
Permissible ambient pressure 600 ... 1200 hPa (absolute)
Maximum operating altitude 2000 m above sea level
Pollution degree 2
Gas inlet conditions
Sample gas pressure
• Without pump
before device: On the inlet side, the overpressure of the gas with respect to
ambient pressure must not exceed 45 hPa.
after device: On the outlet side, the gas outlet must be depressurized
against ambient pressure.
• With pump
before device: Depressurized suction mode
after device: On the outlet side, the gas outlet must be depressurized
against ambient pressure.
Sample gas ow 72 ... 120 l/h (1.2 .. 2 l/min)
Sample gas temperature 0 ... +50 °C (+32 ... +122 °F)
Sample gas humidity < 90% RH (relative humidity), non-condensing
Note
Since measuring ranges can be changed, all accuracy data applies to the ranges specied on the
label!
