Testing a tiny Chinese $2.20 analog multimeter with 1000V AC / DC range. This little thing has very small probes, thin cables and loose plugs. There are tiny SMD resistors in it, about 0.6mm spacing between PCB tracks and no fuse! And this has to handle 1000V AC / DC. The scale and the screws are rusty and the battery doesn't fit into it properly. I also have an older version of it (about 15 years old). The only difference is that the old version had THT resistors, the new one has SMD ones (and this makes it even worse). If you really want to use such multimeter, use it only for safe voltages and low currents.

Well, in all honesty, its so simple and with higher quality resistors, it'll be a good device to teach kids. Let your kids discover the world of electronics, without a 400€ Fluke or Metrawat Multimeter. Just like you, I had one of those cheap toy multi purpose instruments my dad soldered a 1A fuse in series to the leads. It worked for 3 years and it reached me a lot about the value of good equipment.

@RODALCO2007 5 лет назад

Awesome smoke test. Dangerous small SMD resistor for the 1 kV range. and very close CCT board tracks. Keep up the good work.

@JoseSilveira-newhandleforYT 5 лет назад

I generally buy these multimeters to use the movement only (print a new scale and glue it to the existing panel). You tested the old multimeter and it gave out smoke - that's because these old models use smoke signals for high voltage :-)

@redoverdrivetheunstoppable4637 4 года назад

yes, i used those multimeter indicators as VU meters onto an amplifier, they are slow to move but if you cut away the needle and replace it with something more lightweight (the original seems aluminium) like a black brush hair it moves slightly faster, sadly they are becoming rarer bought locally

@Pyridox 7 лет назад

I would never try to use that to measure 1000 volts, probably not even 220v or 110v mains voltages with that particular meter. The looks of the build quality shows that it is questionable, and no fuse. But for someone needing to measure small DC voltages (perhaps 1.5v - 24v) voltages, and resistance, without need for high accuracy should be fine. I know some folks that bought these just for the meter itself, to build custom testers, etc.

@rgones 6 лет назад

It's useless for small voltages as well. I bought one on a local store just for the lulz and it measures 5v right, but when I feed it 3.3v it measures 1v. It's just a toy.

@radionutio81ij79 6 лет назад

Yes I would agree low priced multi meters have a place in low voltage testing, zero to 24 volts ideal but when dealing with mains voltages and above a good meter is paramount. Fluke models or similar and of course a digital meter would be a better option than an old analogue style meter. I have two meters a very expensive fluke and a cheap lasar branded digital type the lasar meter cost approx 6 pounds the fluke 260 I would not attempt to use the lasar meter on the mains supply but it's ideal for automotive electrical repair, and it's not to bad on accurate.

@rogerd4559 5 лет назад

that is a meter you would give to your child as his first meter. But caution them not to measure high voltage with it only batteries. I have an old Simpson meter and it states in the cautions, do not touch the meter while measuring high voltage. Turn off the power before connecting or disconnecting to the main power

the meter electronics do seem to be well made. too bad the manufacturer doesnt offer two grades of quality for that meter for a higher price of course. I would love to see you post that diagram of your ESR-meter modifications. I have two commercial meters with ESR features and they dont agree with each other. completely different readings!

@emelitoduran1571 3 года назад

That was my first ever multimeter back in 83, and it was in kit form, I remember being so happy after assembling it that I kept it beside me when I go to bed, fix many of my relatives radios. I gave it to a friend whose into electronics also and boy was he happy, my parents bought me a sanwa 360tr for christmas. It is still a nice meter for newbies just like he said use it only for low voltages, but it can safely measure up to 220v ac and 500v dc

@RODALCO2007 5 лет назад

Chinese battery is AA- and 3 mm shorter than regular AA's.

@Velktron 5 лет назад

Actually the specs for AA batteries are quite lax, allowing for several mm in length variation and, what's worse, allowing 14.0-14.5 mm for diameter and no clear spec on electrode height/thickness or shape. Often rechargeable AAs are at the very limits of the specs, and won't fit properly in many devices that accept slimmer alkalines or zinc-carbon batteries.

KCTV Programme 'Recording it's normal, Never put the multimeter in amp mod directly in the mains because amp is I = U/R, you need to put a resistor between the multimeter and the plug

@1pcfred 6 лет назад

You are supposed to connect a meter in series with a load to measure amps. When you put a meter into an outlet you are shorting it out. There is a wire shunt inside the meter that the current passes through. The meter just measures the current across the shunt. Outlets can deliver a lot of amps instantaneously before a breaker trips. Enough current to blow stuff up. But I guess you know that now.

I'm a little wary of Harbor Freight digital meters on 120VAC, but I've never been bit. I'm pretty careful, since I used to measure 40-50,000 volts using a big Tektronix probe with SF6 insulation.

@rogerd4559 5 лет назад

A high voltage probe is the only way to measure high voltage and be safe If you must measure high voltage shut off the power connect the meter then turn on the power. do not touch the meter. That is what my Simpson meter instructs you to do on my old model 260

They actually used it for dc low voltage and they used to fixed the small ends of the probs with the pcb board by soldering. It was enough for their work. I bought it for 80 taka= 1 dollar. Still I have the red prob.
