2.3 Control Board Inputs
The SP2 control board inside the chassis has three inputs for sampling external voltages and
recording the data in the housekeeping file. These inputs are J13, J14, and J15, corresponding to
Aux Input 0, Aux Input 1, and Aux Input 2, respectively. Pin 1 of the connector is the signal input
and pin 2 is the return. These inputs have buffer amplifiers so that low-level signals can be
connected to the inputs.

Unpacking and Setup
3.1 Unpacking
The SP2 will be shipped in two cartons. One is a case specially designed to fit and protect the
analyzer chassis. This case should be saved and used to return the analyzer to DMT if service is
needed. The other carton will contain the sample pump, keyboard, monitor, cables and other
accessories. Check both cartons for damage immediately upon receipt, and notify the carrier and
DMT if damage is noted. After unpacking, remove the cover from the analyzer chassis to look for
components shaken loose in transit.
3.2 Set Up
To set up the SP2, follow the instructions below.
Note:
Users who have the SP2 with an Auto
Sampler and Nebulizer should consult
DOC-0318,
the
Set-up and Operation Manual for the SP2 with
Auto Sampler
for this procedure.
1.)
Using Poly tubing with ¼” Swageloks (included), connect the exhaust port on the SP2 to the
