Unfortunately Ametek at Farnborough (where the 7081 was designed and manufactured by Solartron) are no longer calibrating the 7081. I was by there about the time your meters were being calibrated, Joe. I’m not sure they’re even in business now as the last time I was by the business park in February this year their sign was gone.
