new test leads required

[sparkycomuk]

Hello all.... this is my first post,
on previous NICEIC assessments i have been told i require new test leads, due to fluctuating readings. I know this is caused by dirt and dust, as we all work in a dusty environment, has anybody tried spray switch cleaner to clean the connections on the tester and leads, ans does it work. .... Thanks ...Mark

Hi. Yes contact cleaner works for me. However if the battery's are good and after cleaning I still get high readings for example when zeroing the leads (we all know what they should normally be like), then I get a new set.
