I had the oppurtunity to serve in the United States Army for 8+ years as
a Test Measurement and diagnostic equipment specialist. I repaired and
calibrated many types of power meters including my own. The best meter
I found for repeatibility was hands down the bird. Most of this
equipment that came to our shop was usually abused badly. However when
it left our shop or any other Military PMEL shop you can bet it was
accurate to manufacturer/military specs that was traceable to NBS (now
the national institute of standards and technology).
Bottom Line Carl's right, if it is not calibrated in this manner you
don't know or can't prove how accurate it really is.
