I have a 1000w metered Bird Termaline #694 oil filled wattmeter that is not reflecting
accurately the power output level. When contrasted against another calibrated 1000W
device, the Bird registers about 800W. The non-inductive load measures a perfect 50
ohm input so the problem lies elsewhere. The factory manual indicates that there are
no means available "in the field" to adjust the internal circuitry for proper
calibration. I'm not certain if that is a veiled invitation for the need to send it back
to the factory for big bucks servicing. Radio amateurs are well known for their ability
to overcome a whole range of obstacles, consequently, this posting is made in the hopes
of finding a solution if any to the calibration problem. Any assistance would be
greatly appreciated. Ron W2CQM/3
