The polarity of the Z-Axis output can be inverted by set-
ting $501 on the A2 PC board. This switch is set at the

negative (< —5V) intensifying pulses and OV baseline.
To gain access to this switch:
1, Disconnect the 3314A from its power source.
2. Remove the top handle and then the top cover.

Assembly shield to the main deck. See Figure 2-3.
4. Raise the A3 PC Assembly on its hinges to expose
the A2 PC Assembly.
5. S501 is located at the left edge of the A2 PC

blanking pulses. "ВІК--" is for positive blanking
pulses.
7. Re-assemble the 3314A.
