Cheers Jay, understood - the meter is very old with a damaged read out, proper nuisance for inexperienced user.
Going to order another one but in the meantime popped the old,one apart, fuse looks okay but battery flat as proverbial pan cake, went to change it pulled the terminal off lol
Soldering iron out this evening, will have another go tomorrow
Picked this one out due to Amazon reviews, it looks like a dummies version for..don't say it..
