Tolles praktisches Testgerät für die Jackentasche

Funktioniert einwandfrei, vor allem die Oszilloskop-Funktion ist sehr praktisch.

I mainly do DIY projects and have collected a half dozen clamp and multi meters and this one is very accurate and works great. The real reason I bought this was to test the sine wave output on my 5 generators. For that this is perfect since I can just plug the probes into the OUTLET on the generator and see the waveform on the meter display. I like the fact that it has a rechargeable battery / USB built in. No complaints at all!

Gute Ware,danke.

Kompakt,angenehme Bedienführung.Tut was es soll.Bin zufrieden

Ist günstig und funktioniert super!

For the money, for any amount of money, this meter is a very nice value. I wanted it to primarily check sine waves from gas generators. This performed very well under various loads and gave me a good oscilloscope view of sine waves to determine which generators could be used on more sensitive electronics. Just exactly what I needed.

I want to clarify the details of the signal generator.To access the signal generator, first put the AT312G into Voltage measuring mode by turning the central dial to "V". Then long-press the red brightness/signal generator button just above the dial. It will start putting out a 1 kHz, 3.0V pp (peak-to-peak,) 50% duty cycle square wave. Pressing F1, F2, F3, or F4 will let You change the settings for the signal generator. Briefly press the "AUTO" button to turn the output on or off. We want to leave it on the default settings for now.To measure the waveform your meter is putting out, insert the pointy end of the red lead into the "Out mA" jack. The dial should already be pointing at "V." Change to oscilloscope mode by long-pressing the "AUTO" button. Because the default vertical scale is 200V, and the maximum output of the signal generator is 3V pp, you will see a rough line. Briefly press the "AUTO" button to have the scope zoom in on the signal. You should see something that looks like a square wave.To measure the output using the DMM features, long-press the "AUTO" button to change to DMM mode. Because your dial is set to "V" volts you will see the default voltage measurement, which will not be what you expect. This is because the meter is trying to measure DC volts, and you have an AC signal. Pressing the F3 button under "SEL" will select AC instead of DC. Now you will see something like 1.366Vm which is close enough to the RMS value of a 3V pp square wave. Note that the meter auto-ranged to the 6.000 V scale.While in DMM Voltage measuring mode, press "F3" under "SEL" a few more times. You will cycle between frequency (1.000 kHz,) duty cycle (50.15% is close enough to 50%,) DC Volts (~000.1,) and AC Volts (~1.366 V RMS.)Back in AC Voltage measuring mode, pressing "F1" under "REL" is for relative measurements. It's kind of like using the tare feature on a scale. It adjusts so that the old measurement is now 0 V.Pressing "F2" under "P-H" goes into peak high mode. The meter to remembers the maximum and minimum voltage measured while in this mode.I already covered pressing "F3" under "SEL."Pressing "F4" under "RNG" adjusts the range. It cycles between 6, 60, 600, 1,000 V. It does not go in that order, but you can get to what you need, or you can press "AUTO" at any time to get back to the 6.000 V scale.Turning the meter off resets the signal generator to its defaults, including turning it off. I like this, but it will cause me to spend 30 minutes debugging a circuit one day only to learn my signal generator is off.The AT312G is my new favorite electronics test equipment toy, and I have a lot of them. It lacks a BNC plug, relying on 4mm banana jacks for oscilloscope measurements, and it is only single-channel, but I can live with that.

Zuerst mal Vorsicht wenn ihr Spannung von 230 Volt messen wollt.und man sollte einige Kenntnisse haben .Das schreibe ich auch deshalb weil sich das Multimeter nach ausschalten wieder auf DC umschaltet daher auch den 1 Stern Abzug .Das Multimeter ist Vielseitig und es warnt bei Spannungen die Lebensgefährlich sind .Die meisten werden es Kaufen weil es den Sinus einer Powerstadion anzeigt aber Achtung schaltet es erst auf AC um denn es zeigt meist DC an .nach längerem Drücken der Auto taste könnt ihr euch Sinuswelle und die 49 50 Herz anzeigen.Aber auch hier zeigt es manchmal DC an beim durchschalten ich hoffe es ist Anzeigefehler Die anderen Werte ist Alles so richtig und das teil Arbeitet innerhalb der Messtoleranz.

Das Multimeter entspricht der Beschreibung und funktioniert!!!

This is a fine digital multimeter. It works very well and it’s easy to use and it’s pretty standard for those functions. Display is much easier to read than my other meters. As far as the oscilloscope part I am not really sure yet. It doesn’t seem to have the functions genarion capacity of my normal oscilloscopes. You have to select from some pre-programmed settings and you cannot input your own voltages. And it doesn’t look like the wave is smooth. It’s digital so I understand it’s going to be discreet steps but it seems a little coarse.The probes are not shielded and there’s no shielded connector so you’re going to have to worry about noise as well. I think this unit has come down in price to the point where it’s about the same as a good multimeter so, even though it would’ve been nice to have a more feature generator, I wouldn’t go down to three stars. for the screen alone this will be my go to multimeter of choice.It does come with a nice case which I appreciate because my other meters did not come with the gates at all. And it has a rechargeable battery that is replaceable. So you don’t have to dump this in the trash when the battery no longer holds a charge and you don’t have to constantly feed it a diet of expensive 9 V batteries. That alone is almost worth the price.I’m gonna play around a little bit more with the oscilloscope part and I plan to update this review.

I've been in the market for an oscilloscope, however just can't justify the price of most professional ones.This is very nice though, it can do enough for a beginner and once you're done with it as an oscilloscope a very good multimeter lays underneath.The multimeter is way better than my old one, way more modes and settings to use.The only thing I will say is that you need the manual because it is very confusing at first.
