Multimeter uses

[macka09]

Hi all

Are there any decent courses to take to help a complete novice learn how to use a multimeter to diagnose boiler faults?

 

[lame plumber]

but john reginalds book on combis or central heating, they are comprehensive in how to use them

 

[ShaunCorbs]

U tube and installer courses eg baxi, Worcester etc

 

[AllyBongo]

Baxi course is good

I haven't got a clue how to use em. I'm now getting sent to break downs and I'm struggling lol

that's actually a good way of learning, you'll learn quicker

It can be, it could also be dangerous lol!

A quick watch of the basics on a YouTube video would be a good starter tho

there are a lot more people out there with a lot more know how than me and were just waiting for them, in the mean time boilers are largly switches eg overheat stat switches can be tested in continuity or loads fan gas valve etc which can be tested in resistance so all of your testing is done with power off start safe stay safe and wait for someone to point the way

basicly you need to know two things how to test voltage and how to check for continuity voltage is done live and continuity dead

 

[Pssst]

I would say that unless you have at least a basic knowledge of electrical theory, use of a multimeter then you should not attempt to use it on mains voltages.

You could get an electric shock and/or cause damage to appliancees/ electrical installation.
