Bluetooth Multimeter Digital Tester Auto-ranging TRMS 6000 Counts Ohmmeter for AC/DC Voltage,Current,Resistance,Continuity,Capacitance,Diodes,Temperature Meansurement,Volt Meter for Automotive

Previously I left a long review for this meter. I just bought a second meter on Amazon Prime day to test out the Bluetooth DMM app connecting to multiple meters. The app is well designed for multiple meters ( up to 4 ). There were a couple of problems during setup I would like to share here: -The app is no longer on Play Store and the QR code in the listing is not working. I Google search the app and found a website with the apk file for the app . Later I accidentally found that there is a QR code at the back of the meter and which points to a download site of the app for both IOS and Android version. - During setup ( press the yellow button while turn the meter power on to disable auto shutoff, long press the Hz% to turn on the bluetooth function of the meter, click one of the Bluetooth symbol in the app to establish first time connection) , the app has a minor problem: it keep showing scanning until you click on the corresponding line " Bluetooth DMM Disconnected " , then it changes to "Connected", and the bluetooth symbol on the meter stop flashing. Once setup, the Bluetooth connections are done automatically after you turn on the bluetooth function of the meters. I like the customize function, which will do real time mathematical calculation of the readings of the meters ( and plot out in a graph ). For example, if you measure voltage R1 with meter 1 , and current (R2) with meter 2, you set up a formula R1xR2 , the customize function will display the power.

It works as expected which is all you can ask for with this type of equipment. I verified a few measurements with a Fluke and they were very close. The bluetooth range is good, about 75 feet indoors. Some things you may want to know: 1. The LCD is large and easy to read. The backlight works well. 2. Has some useful features I didn't expect such as Relative and Min/Max readings. 3. The case is not covered with a shock absorbing cover, just hard plastic. It slides off the bench easily. 4. The leads are a little short, about 30". The are pretty flexible, but not as much as a Fluke. 5. The alligator clips do not connect to the probes, but it comes with a second set of leads that they screw onto. Changing leads to just the alligator clips is not convenient. 6. I haven't had it very long so I can't say anything about battery life.

For anyone having trouble connecting to an iPhone: this device appears to use Bluetooth Low Energy (BLE), which doesn’t appear in the regular Bluetooth list under Settings → Bluetooth. Instead, it connects through the companion app (download it from the App Store). Before opening the app, go to Settings → Privacy & Security → Bluetooth and make sure the app’s switch is turned ON — that gives it permission to see the meter. Tip: If you have a newer MacBook with an M-series chip, you can install the same iPhone app from the Mac App Store and use it there too. On macOS, the app usually has Bluetooth permission enabled by default. (And just like on iPhone, you won’t see the meter listed under the standard Bluetooth settings — that’s normal for BLE devices.)

I like a lot of things about this meter, the variety of functions, large display (with backlight), ergonomic shape that fits nicely in your hand, the stand on the back and of course the BT capability which is what tipped the scales to buy it for me. However as other reviewers have noted the Bluetooth meter App can only be used in "Visitor" mode and I am assuming that is why the remote commands don't work. The App will read the meter values, but I cannot get the meter to switch modes with the App. In order to register you must enter a code that is sent by email. By the time you get the code the App has timed out. This time-out needs to be increased to at least 5 minutes. Most secure sites the use a code allow 10 - 15 minutes. More comprehensive instructions would be a plus so that you are not left guessing and experimenting. I have the same issue as another reviewer trying to download the App. I'm reading the on-line instructions and trying to read the QR code didn't work. That's when I realized the QR code on the back of the meter is the one to use. It would be nice to be able to use the QR code in the on-line instructions as well. Once I go the App it was a little confusing at first to get it connected, but once working it is a nice way to remotely view the readings. Again a little more information in the instructions would help greatly.

Perfect for my hobbyist needs, replaced an an8008 that worked just as well as this (unit was lost, not replaced due to failure). The meter reads reliably, main leads are decent and comes with a cheap bag to keep everything together. For the price, it's a great meter that's hard to beat. I don't use the app or Bluetooth functionality. Only thing I will note that isn't an issue for me but may be for you, there aren't any rubberized edges so the unit would probably a pain to use primarily as a handheld meter without some tape or something.

Good prodact in a very good price

My phone wouldn't connect to the Bluetooth. I tried a Bluetooth sniffer and it isn't broadcasting at all when put in pairing mode. Also I reads 1.5v off on AC or DC. It's crap and the probes are nowhere near being rated for CATIII. Scam product and more then likely UNSAFE.

I like this meter. Resistance is quite accurate over the common ranges, up to multi-megaohms, and decent at 1 ohm. I also like that it can read small AC signal riding on top of a larger DC voltage (good for seeing ripple on DC power supplies, if you lack a scope). I had to return the first one I received due to some missing parts (some of the attachments), but Amazon rectified that and I had a new complete meter within 24 hours.

06/0823: Ese es el problema de este multímetro: todo bien hasta que llega el momento de instalar la app. ¿Quién es el valiente que instalará una app china en el dispositivo en el que lleva su vida? La app no es de ANENG, es de un tercero. El multímetro es barato, los accesorios son baratos y se siente barato; sin embargo, en pruebas preliminares la exactitud y precisión son muy buenas, cero quejas en este punto tan esencial. No trae funda de silicón, así que si se te cae se te va a partir en pedazos. Y por el precio debieron usar baterías recargables. LA APP NO ESTÁ EN LA APP-STORE DE ANDROID, sino que hay que descargar un archivo apk de un dudoso sitio chino con instrucciones en chino; desde ahí empezamos mal. Luego vienen los PERMISOS: ubicación, fotos y audio, ¿para qué? Lo que hice fue instalar la app en un teléfono FUERA DE LÍNEA, sin acceso a la red celular ni al wifi. Existe un grupo de hackers haciendo ingeniería inversa a la app, y más adelante voy a preguntarles si observaron algún tipo de problema con la seguridad, mientras tanto lo usaré fuera de línea. TIP: Si fuiste lo suficientemente valiente e instalaste la app, NO TE REGISTRES, entra en el modo visitante. La app sirve a dos propósitos: es una extensión del display y puede guardar datos. Como extensión de la pantalla te menciono que no se puede personalizar, viene fijo y debes vivir con ello. No obstante, la gráfica tipo osciloscopio puede ser de ayuda en muchos procesos lentos, como carga de baterías o control de temperatura. Así mismo, el almacenamiento de datos puede ser de bastante utilidad en este mismo tipo de procesos para llevar a cabo un análisis a posteriori. En el mercado existen muchos multímetros con conexión RS-232 o USB a una computadora; sin embargo, los programas son para Windows y yo soy usuario de Linux, por lo cual no me servirían y por eso opté por la conexión inalámbrica, aunque intuyo que será muy latoso generar los datos y luego pasarlos a la PC; pero bueno, así es la vida en Linux =) No lo voy a devolver, pero es una lástima que un producto tan innovador sea opacado por una situación tan delicada como una dudosa app.
