I'm hoping someone out there will be able to help me.
I have recently had the above tester ( Insulation & continuity) calibrated and the other day decided to change the batteries, (wasn't convinced of the readings I was getting)
Straight away all readings were different, I was happy, however.
I've been testing 3 different ring circuits T&E 2.5/1.5 and the end to end results are puzzling me, or am I being picky? (new spark)
Sample of results
P-P .20 .19 .18 .10 .09 .11 .20
N-N .20 .19 .18 .09 .09 .11 .22
E-E .44 .44 .43 .31 .30 .30 .47
Am I correct in thinking the E-E should be approximatly 1.67x the P-P& N-N
So I got a newish 2.5/1.5 roll of cable and got P-P .32 N-N .32 & E-E .62!!!!!
Am I too picky or has any one else had a similar experiance? Any advice greatly appreciated
