Hi
Can anyone explain how to null the earth lead on a Primetest 300
I've looked and looked but still can't find the answer

Hi Warwick,

From when you turn the Primetest 300 instrument on, press the right hand key continuously until you get "RPE" in the top left hand of the corner of the screen - from here you will see "ZERO" above the F2 key.

Press this to effectively "NULL" the Earth lead.
