Access the Calibration Switches and the Battery
The Control board is located on the outside of the Constellation board. It must be removed to provide
access to the battery and the P600 board, which are both locate on the Constellation board.
1. As shown in the figure, disconnect the ac input wires from the ac connector. Move them to the side
so they will not interfere with accessing the switch or battery. If your unit has the optional GPIB
board, you can access the battery and calibration switches directly as shown in the last figure.
Note that only the MP4302A units have a ferrite core installed on the wiring.
Lift the orange locking
tabs all the way and
remove the ac wires.
Move the wires to the
side as indicated by the
arrow.
2. If your unit does not have GPIB board, you must also remove the shield located underneath the ac
wires.
