Testing Electrics?

Post by Jaeger_S2k » Wed Dec 27, 2006 1:30 pm

I have a rather older multi-meter a TMK 500. From my Ham Radio days.

What would you recommend I replace it with, something from the Fluke range, compact but will allow me to do the basics and a bit more.

What are the basic tests that I can undertake with my multi-meter and what/how to do them?

Continuity -

Polarity -

Etc...

I have a fluke 77

The basic checks are

earth continuity

resistance to earth

short circuit

Have you ever considered taking that to the antiques roadshow :lol:


If I was to buy a new multimeter I would get one that has two sets of probes, one set for probing and the other set that clips onto wires etc. This makes testing much easier.

I have to say that I prefer analogue rather than digital, somehow I just don't trust digital ones, especially when they start oscillating.

I had an anoulgue one for about 15 years and it was great, I left it in the boot of my car and it leaked in and I had to throw it :cry:

Ebay had some clamp meters :lol: and so I bought one of these, it also came with probes. The probe's work but the clamp meter bit did not work :cry:

The fluke meters seem to be what the pro's use, but many of these are expensive. The one I use now only cost about £15 and does everything I need. If it can measure resistance and voltage I am happy.

A good feature on the continuity test is the bleep function, this can make testing fuses etc. much easier.

You just reminded me of a guy at work that went to Maplin.

He got a multimeter and volt stick for less than £10 I don't think the offer is still on, but they still have some cheap test equipment :shock:

Thanks.

Maplins are always worth looking at.

Err - AFAIK the Fluke 77 is just a multimeter - don't think it goes low enough (200mV FSD) or with sufficiently precise resolution (10 milliohm) for it to be used for continuity, R=+R2 etc.... ??


I'm sorry - I can't come in to work today, the voices are telling me to stay at home and clean the guns.
