[TowerTalk] Inaccurate Bird Slugs.

[Maurizio Panicara]

Before trying to adjust anything you should use a dummy load and check if
the plug in error is constant over the band range.
If the reading (error) is not constant with frequency the problem is in the
coupling and/or compensation.
The parts to check and correct for this occurrence are under the teflon cap
but this is a job for qualifyed and trained personell only.
If the error is constant and moderate you can try to adjust by yourself the
trimmer that's located under the aluminium metal plate, that one indicating
the plug type and power rating.
After the circular plate is removed (heating a bit the aluminium plate with
an hot air stream helps, but this removal is not an easy task) a hole is
visible and trough it you can adjust the reading using a small screwdriver
and a calibrated reference.
....of course I take no responsibility.
