caveo security Posted October 22, 2016 Share Posted October 22, 2016 I have a question as I never done that. Will anyone be able to tell me step by step how to do resistance reading for NSI ? I know each zone need to be measured but can anyone tell me how should I do it ? Please ? Quote Link to comment Share on other sites More sharing options...
PeterJames Posted October 22, 2016 Share Posted October 22, 2016 I think you really need to try and find a basic electronics course at you local college, or a night class. Using a multimeter is the most basic elements of this industry and if you dont know how to use one, and clearly you do not, you should not be doing any work at all in this industry. Not understanding how to take basic measurements in this industry is like wondering around a crowded tube station blindfolded, your gonna bump into something sooner or later, lets hope its not a tube train. Honestly I wouldnt employ a trainee that doesnt have the basics, you would not pass our interview exam. I am giving advice here not taking the P, get on a basic electronic course once you understand the fundamentals you will have a much better understanding of whats going on. But asking us to teach you the basics is asking for trouble, because someone will rip the pss Quote Link to comment Share on other sites More sharing options...

datadiffusion Posted October 22, 2016 Share Posted October 22, 2016 Agreed should not even be on site, supervised or not, at this level Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment Share on other sites More sharing options...

datadiffusion Posted October 22, 2016 Share Posted October 22, 2016 (edited) 20 years ago might have had a chance, now the distinction between and alarm and a 'home automation' system would keep the courts busy for years... The ultimate test of 'is it an alarm you're installing?' would be an external siren I suppose, but hardly anyone DIY / low end fits them. I don't even fit them if it's monitored!

Nova-Security Posted October 22, 2016 Share Posted October 22, 2016 Not a dig, but "Do you own a Multimeter" Resistance readings for circuits is the easy part, and something than should be do regardless of the NSI / SSAIB Quote www.nova-security.co.uk www.nsiapproved.co.uk No PMs please unless i know you or you are using this board with your proper name.

caveo security Posted October 22, 2016 Author Share Posted October 22, 2016 I do own multimeter... I'm just asking because it's not working for me. I was told to twist to spare cables in each device together and measure resistance on those two cables in panel site. But each pir I have measured shows me 0 so clearly there is something wrong. The reason I ask was just simply to make sure that I'm doing it right. Quote Link to comment Share on other sites More sharing options...

MrHappy Posted October 22, 2016 Share Posted October 22, 2016 move dial to diode test (between 2ac & hFE) touch probe togther & does it buzz? Quote Mr Veritas God Link to comment Share on other sites More sharing options...
caveo security Posted October 22, 2016 Author Share Posted October 22, 2016 Yes it does I've check that in the first place. Quote Link to comment Share on other sites More sharing options...
lymebayalarms Posted October 22, 2016 Share Posted October 22, 2016 So turning it back to 200 ohms, touch the lead together what value do you get? Quote Link to comment Share on other sites More sharing options...
caveo security Posted October 22, 2016 Author Share Posted October 22, 2016 0 all the time 0. I have just checked on resistor and showed 0 as well. Obviously on kilo ohms I checked. So I just think meter is faulty? Quote Link to comment Share on other sites More sharing options...
lymebayalarms Posted October 22, 2016 Share Posted October 22, 2016 So with the meter set to 200 ohms you get 0 with the leads shorted together, what about without the lead touching, what does it display.... Quote Link to comment Share on other sites More sharing options...
caveo security Posted October 22, 2016 Author Share Posted October 22, 2016 Yeah it's display only 1 like it's ready for measuring Quote Link to comment Share on other sites More sharing options...

caveo security Posted October 22, 2016 Author Share Posted October 22, 2016 Well then why it's not showing anything when measuring simple 2k2 resistor? Anyway I'll test on other multimeter on Monday will see but I think it's faulty. Quote Link to comment Share on other sites More sharing options...
