Fun project and a working multimeter for your effort.

Just follow the directions. I used an LCR meter to confirm that I have the correct component in hand as I'm still very new to the hobby. I doubt that I'll ever get the hang of reading resistor color codes. Checked the multimeter readings against other multimeters that I have on hand, and they reasonably matched in values.

Fun project, good instructions.

Like others stated, this is NOT a serious meter for lab work. Will it work good for testing if things are dead or not, yes. The instructions were good and I like that as a learning kit it really shows how the schematic of each function works which is nice to know. Now for the bad, like many other my inductor was bad, I was able to cut the plastic away and resolved the issue with some blobs of solder. Also like others my vari pot is questionable, if I press in it works. I plan to open up the vari pot to check the contacts and if that doesn't work ill just replace it completely. Overall these kits are still worth it since they really do everything they can to guide you on troubleshooting too in the manual. I can't give it a 4 or 5 just purely on this inductor and vari pot issue seeming to be an ongoing supplier qc issue. You don't learn from your successes but that doesn't mean you should plan to fail.

Good accuracy except ohms

The kit was fun to build and the instructions were excellent. The only problem I had assembling was the buzzer. When I tried to tin the buzzer as the instructions said it just melted. Had to turn the temperature of the iron to low and use a small tip. Touched the buzzer quick with the soldering iron then it worked without melting. Wish the instructions said that. The meter accuracy is within the 3 to 5% on all functions except the resistance. The resistance reads within 3% up to 10 on the dial on all ranges. Past 10 it reads from 4 to 10% higher than my Fluke 179. I take whatever the meter is reading and subtract one division on ohms scale if reading is above 10 from reading and then the accuracy is about 3% compared to my Fluke. The buzzer works but sounds wimpy. The pointer doesn't want to stay on 0. When changing ranges or moving meter it moves a little and have to readjust. When calibrating had to adjust pot all the way to the end of it's range to get .4 volts. The pot should be more in the middle of range. I guess it's not too bad for the price. Don't expect it to be as accurate as a digital meter. I bought it to test transistors and diodes for leakage and checking potentiometers. A digital meter doesn't read leakage unless it is very bad.

It is a kit with detailed instruction. I think it is potentially good product. My kit has a bad potentionmeter for zeroing ohm range. The potentionmeter resistance jumps around. It also has a broken inductor for buzzer. The case quality is in par with $15 analog multimeter, details are not good. the face was not glued flat. Internal PCB has good quality, the probe is high quality if compared with most $15 meter. The range switch is only copper without any plating to prevent oxidation. The meter needle balance is 1-2% off if put in position other than horizontal' but can be trimmed to be perfect. The voltage can be adjusted to be within 1%, but some the ohm meter shows 10% mismatch from ideal value, bad zeroing could contribute to some excessive error. Overall, I had fun building one meter, extra imperfection provides more chances of trouble-shooting, maybe it is purposely designed that way? I fixed the broken inductor by carefully re-connect the fine wire winding for the inductor, on second thought maybe I broke it, so bend the inductor feet very carefully or it easily breaks. After fixing it, the buzzer works. For the potentionmeter, I re-assembled it and apply some contact cleaner, now it works. The linearity of the analog meter is not very good, the excessive error comes from the nonlinearity. it is about 2% near the center scale. it is still within 3% of specification though, but causes 20k resistor reads 19k.

Kit

The kit is very informative and the direction are so easy you do have to use math at all on series or parallel resister circuit installs. You just follow the pictures mainly. Also pay very close attention to the pot switch. It doesn't go on the resister side of the board. Other than that it pretty easy. Don't overload the solder and make sure you dial pas have no solder on them you good to go. I measured all the resisters before install and the margin of error is higher than the package says they are. I had 6-7% +\- on over half of them and the book said 1-2% +\-. so that is the really solid error I found with the kit. The other thing that I found was that my soldering iron had to be set to 3.5 out of 5 to lay the solder and it didn't stick to good. My suggestion to fix that is to wipe the board down really good with alcohol and flux all the pads. Good tool

Great experience

The media could not be loaded. Note: the leads in the photo do not come with the kit. This is an excellent kit for soldering practice. All the pieces were there and the instructions were easy to follow. As with all of these kits the solder is crap. One of the components failed. So why 5 stars? Because Elenco sent me a replacement part for free and the purpose of this kit is not to have a super meter that can stand the abuse of a truck garage. The purpose of this kit is too learn new skills. "The journey is the destination" and this is a journey worth taking.

Not as I remember

I have in the distant past (90's) put together a few of these meters and never had any issues and worked as designed. I recently ordered this item thinking it would be fun to do again.. the quality of the parts has fallen a lot. Potentiometer is horrible and the selector contacts are hit and miss. This is not much more than a toy really.. Fun to build and learn from but not to use in a serious setting where reliability is needed. So I ordered a second meter hoping that the 10k pot would be better.. humm same issue.. Update: I found a replacement 10k pot.. TTI part# P120PK-Y25BR10K (The thumb adjustment is a bit longer). I ordered direct from TTI but Digi-key and Mouser have this part.. After replacement Meter works as expected.
