Default Re: MFJ Dummyload faulty?

Almost certainly impossible to adjust and might contain beryllium (should be marked). Dangerous to open if so.

61Ohms is not ideal but it is not terrible. VSWR is 1.22:1 if perfectly resistive.

Is the reading stable? Frequent failure with dummy loads is at the connection between pin and resistance element or resistance element to body. Check to see if it changes with slight pressure
on the centre pin or light tapping on a wooden block.

Maybe post the model number and someone might have another to compare readings?
