Can’t agree with you more Rob, buy a multimeter. And unless it’s a Fluke or similar quality use it only on the car.

Just make sure what you buy does DC current, have a look at this one, there is a table in the photos that show you the DC current model:

Just don’t use it on 240/415V!

I’d buy one of these though:

Funnily enough.

I bought a Jaycar meter because at the time it was the onlyAC/DC clamp meter that was in the price range for waht I was doing.

It lasted well for a few years. 

In the meantime, well over a year since I started with my cheapy, one of the fellas where I would end up on wages, used his Fluke and had an ARCFLASH.

The gizmo was less than 12 months old and the guy using it was nearly as old as me.

 

Now.

Standard multimeter issued in UG mining in your area, and actually almost industry standard is the University brand.

You should be familiar with it for HA use.

 

Get a couple of qualified electricians using one of them on 1000V and tell me what you think was the end result.

 

Right now Im learning to fly helicopters.

Theory is great.
But nothing beats the practical.

Its easier to talk to the less technical in terms of ground and earth rather than 0V so it doesnt confuse them more than they already are

 

Cheers

Thanks mate. I have a basic multimeter. How would I have used it to find the problem?

They'll all let go, just depends on what you are doing and where its being used. Fluke and other leading instruments are designed and tested to a strict IEC Standard (has also been adopted into an Australian Standard), University is one of them. Flukes used to let go if you left them on A range and put them on an LV source. They added a HRC fuse inside to protect against that.

 

You'll never convince me that the use of the term EARTH on a rubber tyred vehicle/trailer is a good idea.

 

Nando, I'll draw you up a picture of what the issue can be, so it becomes obvious. Rob might have another method but they'll do the same thing in the end. Doesn't hurt to grasp the same concept from multiple angles.

It was actually the Fluke leads that gave the problem.

All leads got replaced that week.

Meter was only a couple months old too.
