If you are lucky. I calibrate Birds at a nist lab. All are limited to +/-
!0% of full scale or more. They are very nonlinear on frequency. I
personally have never understood the reverence for Bird meters. The only
pluses I can give them is no power required for operation and you can drop
them from a tower and they will survive. I would never rely on them for
anything but peaking a signal or a VERY general  output indication.
