It is not normally necessary to take the top off the MAF, just read the voltage range as you have done and adjust using the adjusting screw, make sure the top is sealed when you refit any moisture getting in there and it is toast. Whilst you were playing with the MAF did you clean the wire, always a good idea regular electrical contact and tuner cleaner works?
