What am I not doing?

[mickyh]

Hi I tested a small RFC. R1 = 0.28 RN = 0.28 R2= 0.46. R1 + R2 when L + N are cross connected = 0.30 (not the 0.14 I was expecting) on 6 out of 7 sockets 0.23 on other socket. I have checked all connections and they seem ok. I'm newish to testing and would appreciate any suggestions

Are you sure they where definately cross connected L1 to N2 & L2 to N1

You'll have to teach us how to test R1 + R2 with L & N cross connected

You shouldn't have a reading at all.

How are you getting R1 + R2 with L & N cross connected

**EDIT**

Wayne beat me to it

I can't even get this to work - so much for giving advice.

Don't think I like the new site much

Hello and welcome

Hi I tested a small RFC. R1 = 0.28 RN = 0.28 R2= 0.46.

Correct terminology is r1, r2, & rn.

R1 + R2 when L + N are cross connected = 0.30 (not the 0.14 I was expecting)

You have carried out a measurement of R1&RN, not R1&R2.

I'm newish to testing and would appreciate any suggestions

Have you done a course? An understanding that R2 represents the CPC and not the Neutral is very basic stuff.

Widdler,

If he carried out the measurement of R1 + Rn, he would have got 0.14 - Not 0.30

Now he said he checked all connections, and they seem okay??

Whhhhoooooooosh.

Straight over my head lads. Wanted to say something to a thread but this is the third I've read and I don't think I'll find a thread that isn't in general chat that I can reply to any time soon. haha

I'm not referring to his measurments, I'm referring to his methods.

Non dart players off the green please. Thank you.

Thanks for the replies. I think. Yes I have done a course although I can see why you might think that I hadn't.http://www.electriciansforums.net/images/smilies/mad.png r1 + rn gives me a reading of 0.30 r1 + r2 a higher reading as you would expect but both readings are higher than they should be for the length of the circuit. The reading is identical at 7 out of 8 sockets and lower at the odd socket (0.23) for r1 +rn.

Have you zero'd your equipment?

 

[rocker]

Ooh and are you sure you've connected them in a 'figure 8' i.e. leg 1 L1 to leg 2 L2 and leg 2 L1 to leg 1 L2? Cost from your first post it sounds like you have only done one connection.

Say that fast three times.

Is that a new way of saying L1 - N2 & L2 - N1

Took me a minute or two to get my head round that one

You knew what you meant

Thought Rocker was SHOUTING !
R1 R2 RN are end to end tests !
