NOTE

Repair

Power Sensor repair consists of replacing either the A1 Bulkhead Assembly, or the

A2 Power Sensor Board Assembly.

The recommended repair strategy for the A1 Bulkhead Assembly is to completely

with a calibration report and a new calibration sticker for the Power Sensor.

Adjustment" on page 45. If you did not disturb the wires, it is likely that no

adjustment is necessary.

Although the recommended Bulkhead strategy is to completely replace it, we are

aware that some customers have both the ability and experience that enables them to

disassemble and repair Bulkheads to a lower level. For this reason, Appendix B

provides exploded views of the various Bulkheads, and tables listing the parts.

Lower level Bulkhead repair can be more economical than replacement, although

this may be offset by the need to invest in sensor calibration equipment and a SWR

test set-up.
