Geluidsniveau Meter, 30 ~ 130 db 9.6 inch Lcd scherm Muur Opknoping Decibel Ruis Meten Tester met Datalogger & Alarm (SW-525B)

Das Gerät macht was es soll.Aber da ich extra die 525B Variante mit USB-Logging Funktion gekauft habe ärgere ich mich darüber 1) dass die Software nur über eine mini-CD verfügbar gemacht werden soll...und 2) dass die CD offensichtlich leer ist....nachdem extra einen uralt-Laptop ausgestaubt habe, der noch ein CD-Laufwerk hat.3) Das ich schon 30 Minuten suche wo ich zu dieser Software kommen soll, weil4) Wenn man das Gerät einfach per USB an einen Laptop ansteckt, der Laptop das Teil nicht erkennt - obwohl das Gerät zwar vom Laptop mit Strom versorgt wird.Schade, hätte toll sein können, weil es ansonsten einen guten Eindruck macht.

It appears to be as described, but buyer should know that it does require a CONTINUOUS, INDEPENDENT power supply, i.e. a permanent charger which is not included in the pack. Luckily, my mobile charger actually works for this recorder, but given the many variable mobile chargers available, this probability should not be automatically assumed by all buyers and the power IS a continuous requirement for continuous use (as opposed to intermittent power supply required for my mobile phone when it needs charging).Not sure yet how easy it is to programme, but the digital display is as shown in the description.

I ordered the SW-525B (the one with the data logger) from Amazon Prime. I received a SW-525A. I sent it back. I repeated the order and got the wrong one again, so sent it back again. I then ordered through Amazon from the supplier rather than Amazon Prime. After some delay, the SW-525B arrived, even though it was in a box that said SW-525A with a barcode label on top saying SW-525B.The instructions are mostly in Chinese. The English instructions are short, incomplete and inaccurate. However, I got the device working without too many issues. Then I tried to download the logged data to my Windows 10 PC. Complete failure. The instructions do not even say where to find the required software. I asked support who provided a link. I downloaded the .rar file (so any non-techies will be in trouble already at this point). After expanding it, I ran the installer. As somebody who has previously written many installers, it was obvious to me that this one is half-baked. After installing, I tried running the software. It failed. After some investigation (even many techies would give up at this point) I located a DLL that had not been installed correctly and manually sorted that out. That got the software running, but the device itself was still not recognised even though it was plugged into the USB port. I searched the expanded .rar file and found some more instructions about how to install the driver. Unfortunately, they didn't work. At this point I gave up and started the return process on Amazon. Unfortunately, the return label that it wanted me to print is not pre-paid, and the device has to be sent back to China. I'll be contacting Amazon to see what they say, but I suspect I'm going to have to jump up and down about my legal rights if I'm not going to be left out of pocket after buying a device that is unfit for purpose.

Nous sommes très déçus car nous avons reçu ce produit SANS le CD d'installation pour lecture des données sur PC . Pourtant le site montre très clairement que ce produit est fourni avec le CD d'installation. Pouvez vous me l'envoyer svp ? On a passé du temps à choisir ce produit et il serait trop facile de nous dire que si le produit ne convient pas il suffit de le retourner. NON ! car ...

Fonctionne bien, seul bémol, l'alarme se déclenche sur des pics, il faudrait pouvoir faire une moyenne sur 2 ou 3 secondes
