5. Switch the calibrated 43i into the span mode.
6. Measure the flow rate into the ZERO bulkhead on the rear panel of the
43i. Be sure that the charcoal scrubber is connected. Note the flow and
measured SO
7. From the flow and measured concentration, compute the permeation
tube release rate.
A 5-10 micron pore size, two-inch diameter Teflon® element is available for
Teflon
the Model 43 i Trace Level-Enhanced. 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" in the
Installation" chapter for information on attaching the cable to the
connector board. For associated part numbers, refer to the "Servicing"
chapter.
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 to the "Servicing" chapter.
Each kit consists of:
one six-foot cable
●
one terminal block
●
one snap track
●
Note Supporting all of the connections on units with the optional I/O
expansion board requires:
concentration.
