Model 400E Ozone Analyzer
Instruction Manual
In its standard configuration the analyzer Analog Outputs can be set for the
following DC voltage signal levels. Each range has is usable from -5% to + 5% of
the rated span voltage.
The following DC Current output options are also available from the factory:
RANGE
0-20 mA
These are the physical limits of the current loop modules, typical applications use 2-
20 or 4-20 mA for the lower and upper limits. Please specify desired range when
ordering this option.
Pin assignments for the output connector at the rear panel of the instrument are
shown in Table 6-9.
