1 Instrument description

With the 891 Professional Analog Out, digital signals of Metrohm ion
chromatographs can be converted to analog signals and processed in
non-Metrohm software.

Like the ion chromatograph, the 891 Professional Analog Out is operated
with the MagIC Net software. When the 891 Professional Analog Out is
connected to an ion chromatograph or an extension module, MagIC Net
recognizes it automatically. The software checks its functional readiness
and controls and monitors all devices connected to one another.

The 891 Professional Analog Out is equipped with two high-resolution
outputs, Out 1 and Out 2, as well as with two low-resolution auxiliary out­puts, Aux 1 and Aux 2. All outputs can be used for transmitting detector
data and information on pump flow, temperature, etc. The output of
detector data on the low-resolution auxiliary outputs is not recommen­ded.
