Installation procedure
1 A top and bottom cover needs to be installed over the reference device located
on the DC Reference assembly. To install the covers, place one cover over the
top of the device and another on the bottom side of the DC Reference
assembly printed circuit board. Use your fingers to hold the covers in place.
Then line up the screw holes in the covers with the screw holes on the printed
circuit board. The covers should now completely enclose the reference device.
2 Line up the DC Reference board with the connectors on the
DC Circuitry assembly. Hold the covers over the reference device in place while
installing the DC Reference assembly. Then plug the board all the way into the
connectors.
3 Use the #TX10 Torx driver to install the two screws on the
DC Reference assembly.
4 Use the Covers installation procedure in this section of the manual to install
the 3458A top cover and top shield.
