P.S. IF you are really desperate, either remove
the silver cover, or drill a hole , about dead
center, in the (Power. Letter, as in ,where,say
1000 C, in the rectangular box),Just the aluminium
plate, NOT any deeper!).This about 6 o'clock position. There is a
calibration pot accessable
thru an access hole in the slug, and can be
adjusted- BUT I highly recommend against it! Jim

Heck best thing can do, is find someone else with a wattmeter, and then
compare the measurement, vs.
your slug/wattmeter. If within +- 5 % don't worry! You wouldn't even
hear the diff at 10 %!, but if memory serves, these are susposed to be
accurate to 5%.. Jim NN7K

I have a 2,500 watt, HF slug that I don't have confidence in. Anyone
know who calibrates slugs for a reasonable fee?

Thanks.

Have you contacted Bird? Last I heard, they were still making equipment.
As to "reasonable" - thats a good question. But then at least you would
know it is "accurate".
