Re: 'Proper' multimeter (Maplin MT2017)
I've checked mine on resistance, they checked out fine. I've checked low volts and current and they're fine.
When I get back to work I can put them across some 600vdc, 1000vdc, 400vac and 1000vac if I'm feeling confident with them.

Re: 'Proper' multimeter (Maplin MT2017)
If this meter, or any other, has a deflection which seems totally erratic, it may be static build up on the transparent window (plastic or glass). Try breathing on the window, or wiping it with anti static solution.

Blob of washing up liquid works well too.

I've now removed the batteries from the meter as a precaution against corrosion, put it back in its box and stored it away in a drawer until if/when I need it. Quote:
I agree that shrouding the probes is a good idea. I generally use earth sleeving for this purpose.

Re: 'Proper' multimeter (Maplin MT2017)
Called in for mine today - cant say I really needed one, but at £7.00, an impulse buy.
Handed the assistant the paperwork and he came back from the storeroom with a plain white box. It felt rather light, so I opened it there and then and a good job too. It was an anemometer. I said 'that's not the correct item' and the lad said 'Oh I just saw 'Meter' and thought that was the right thing'. I explained that it's a MULTI-meter, so he went back to the storeroom, and was very pleased with himself when he returned and exclaimed "I've found it!" You'd have thought he'd found the holy grail! Nice kid, probably just doing a Saturday job, so what the heck. I did buy some sheets of FR4 single-sided PCB sheets knocked down fro £7.99 to £2.99. Yes, those probe tips are an accident waiting to happen if poking around noval or B7G valves bases. So easy to short out the tags.

Took a look at the internals, but no obvious problems, so I suspect the meter itself may be damaged. |
