HI all!!!! Greetings from NEW ZEALAND! I am a quallified Electrician.
I ask this question on these fourms , as my work mate is from Yorksure and he told me that these meters are what most of the Brittish are using. He migrated here about 7 years ago.
I have recently aqquired a metrel 61557 Installation tester , and apart from removing the brittish 13A ( and i must say REAL PLUG , Hate to stand on that bugger in middle of the night!! ) , from the test lead , and fitting a Crappy NZ 10A one......mostly it works well.
Love the tester , and it preforms well , well for the most part but im confused with the loop test part.
It says in the manual its measurment range is from 0.2-2000OHM ,and PSC up to 1220A , or 1.2KA.
that would mean regardless of the actual impedance of the cct.......the MAX ill get is 0.20 , and 1220A prospecticve Current....a bit of a waste of time i think.
What are other peoples views on this meter , what concerns me about this , is that the MAX PSCC i seam to be able to read is 1220 A ( 1.2KA ). Our Little small plug in type MCBs are rated at 3KA, If i put this on a 150+kva transformer , with massive tails , then that be a bad situation!
IF the lowest value i can obtain is 1220A then the actual value could potentially be a lot lower , but how much?
Ive got a recenct "calabration" cert , but the Ze........doesnt go that low....they only tested with a 0.5OHM Impedance.
It does say tho that the "display" results are min 0.00 , and display up to 24KA........
Am i reading something wrong , any other users out there, results?
Many thanks guys!
