    Weber Bias Rite has always worked well for me.

    I've noticed the same thing with mine. Plate voltage through the Bias Rite is lower than what I read directly off pin 3.

    Even still it sure beats the heck out of the alternatives of 1) transformer shunt (scary!) or 2) adding 1 ohm resistor to ground (invasive).

    Every meter has its own built in resistance that comes into play with readings, so no two readings will be the same with different biasing tools. I wouldn't worry about it too much unless the readings are radically different.
