I repair microwave ovens (amongst other items), leakage is EXTREMELY!!!!! rare - I've only ever seen two which leaked, both were the same Philips model with the door hinging downwards. However, both were still well within permitted UK limits (but not USA ones!). We are legally obliged to check every microwave we take apart, so I test a good many every year, and it's not a problem!. I would agree that it's more likely the large magnetic field from the transformer affecting your meter. >If I was you I would play it safe and get your oven checked out for leakage. If it will reassure you, get it tested, but it's unlikely to be leaking. -- Nigel. /--------------------------------------------------------------\ | Nigel Goodwin | Internet : nigelg@lpilsley.co.uk | | Lower Pilsley | Web Page : http://www.lpilsley.co.uk | | Chesterfield | Official site for Shin Ki and New Spirit | | England | Ju Jitsu | \--------------------------------------------------------------/ -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
