Use the screwdriver to adjust the Span potentiometer RV2 such that
the O
2
reading indicates the correct percent concentration. For
example, 25% oxygen span gas should be set to produce a measurement
of 25.00%.

Replace the cover, wait 30 minutes for the instrument to stabilize, and
repeat the four steps in the “Calibration” procedure.
A 5-10 micron pore size, two-inch diameter Teflon® element is available for
the Model 410
i
. This filter should be installed just prior to the
SAMPLE
bulkhead. When using a filter, all calibrations and span checks must be
performed through the filter.
The I/O expansion board provides six analog current output channels (0-
20 mA or 4-20 mA) and eight analog voltage inputs (0-10V). The DB25
connector on the rear panel provides the interface for these inputs and
outputs.
The 25-pin terminal board assembly is included with the optional I/O
expansion board. Refer to “Terminal Board PCB Assemblies” on page
2-5
for information on attaching the cable to the connector board. For
associated part numbers, refer to “
External Device Connection
Components
” on page

.
The optional terminal block and cable kits provide a convenient way to
connect devices to the instrument. These kits break out the signals on the
rear panel connector to individual numbered terminals.
Two types of terminal block and cable kits are available. One kit is for the
DB37 connectors and can be used for either the analog output connector
or the relay output connector. The other kit is for the DB25 connector and
can be used for the optional I/O expansion board. For associated part
numbers, refer “

Each kit consists of:
●
one six-foot cable
●
one terminal block
●
one snap track
