REGULATED VOLTAGE ADJUSTMENT

TM 11-5805-387-34-2

Adjustment precautions: Observe the following precautions when making adjustments.

Before making adjustments, make sure that the front panel meter reads + 20 VDC, indicating proper

regulated voltage.

Before starting a procedure, carefully read all steps to become familiar with them.

Use insulated test probes, or wrap test probes in insulated tape. Use a nonmetallic screwdriver. This will

prevent signals to the module cover from being accidentally shorted.

During adjustment, do not disconnect test equipment until instructed to do so.

Do not use adjustment procedures as a substitute for troubleshooting.

Make adjustments only if the value being measured is outside the given tolerance.
