help testing please

[yido81]

hi all, just practising some testing in my garage, getting the hang of it all, ive wired up 6 lights with switches, and when im doing the insulation resistance test im getting 1000Mohms on my meter, would i be right in thinking that i write this down on the certificate as >999 ?? help me please

why not >1000 if thats what it says on the tin?

i was just curious as a lot of people i know put >299 on theres, presuming thats what there meters go up to!! ive got a megger mit320!! so if i got a reading of say 657 for example, would i put >599?

hi mate as stated above whatever it says on your meter thats what you would put whether it's 692,>299 or >1000.So long as its not below 1M ohm (LV) no need to worry
