Sri 302 Installation

A/D Board Capacitor and Ground Wire Installation

302 and 333 Boards

To prevent loss of communications
the installation of a 0.1 uf capacitor
and a grounding wire to the A/D
data system (302 or 333) may be
necessary. To perform this modifi-
cation you will need a 0.1 uf ca-
pacitor, a 1000 ohm 1/2 watt resis-
tor, a length of insulated wire,
shrink wrap (or electrical tape) and
a soldering iron. These parts can
be obtained from SRI Instruments
for little or no charge.
Gain access to the inside of the
GC by removing the six screws
that hold the chassis to the base
plate of the GC. Tilt the GC up on
its side. The A/D board is located
on the far right of the GC.
Remove the 4 hex screws, located
on the outside of the chassis, that
secure the A/D board to the chas-
sis by using a 5/64" allen wrench.
Pull out the board so that you can
work on it.
