I am already tired of the Siglent service
I must admit that I am really disappointed with the quality of the Siglent service.
I would like to summarize how I have struggled to get my SDM3055 device fixe:
I bought the SDM3055 multimeter (serial no.
SDM305C4140132) in Tomtronix company (
www.tomtronix.pl), based in Poland, in February 2015.
The first problem I observed was about the device not booting up correctly – it was stopping on a startup screen and not loading any further. I contacted the Siglent company representative, and he suggested that the digital boards and the analog board should be replaced. The device was sent to the Siglent service, based in Hamburg, by the Tomtronix company on July 4th, 2016.
The device was delivered back to me on August 2nd. However, I did not receive my device, but another one with an older serial number
SDM305C3140046. You can see that in the pictures: "sdm3055_back.jpg" and "sdm3055_systeminfo_1.jpg"
As you can see not only was the serial number different, but also the installed firmware was older. I received an older device! I complained about that fact to the Tomtronix company, but their only suggestion was to keep the device and use it. I contacted Jexy again and he suggested to send the device again to Hamburg and assured me that my device would be fixed in a proper way this time. This is what I did on August 8th.
I kept asking questions about my device status (September 26 and October 7) as the device was still being fixed in Hamburg. Eventually, I received my device back on October 12. However, it was not fixed!
1. I noticed that the firmware was upgraded since the display layout was different that the original.
2. The device was not operational since none of the front panel buttons, except the „on/off” one, really worked.
I contacted the service again and they let me open the device to see if there are any not connected cables inside. They were all in their places, except the ground cable (
safety!) which was not connected at all. Definitely that was not caused by the delivery. You can see that in the pictures: "ground_cable_not_connected.jpg"
?
Besides, there was a clearly seen bent on a flexible cable connecting front panel with its board. You can see that in the pictures: "fcc_cable_demaged.jpg"
I sent all those information and pictures to Siglent service on October 17, 2016.
I investigated the flexible cable deeper and observed that it was damaged as in the following pictures: "fcc_board_side_demaged.jpg" and "connector_damaged.jpg"
In my opinion those problems could be responsible for malfunctioning of the device. I sent those information on October 18. I did not receive any response by October 20 and decided to fix the cable by myself. I cut it by about 2mm as you can see in this picture "fcc_cut.jpg"
Then I mounted the cable inside the device as shown in the picture: "fcc_repair.jpg".
The device started to work correctly and I run all tests. You can see that in the pictures: "test_1.jpg", "test_2.jpg", "test_3.jpg".
However, I am not satisfied with these as the flexible cable is significantly stretched and may got broken with time and the connector is still damaged and does not ensure a proper mounting.
My further investigation showed that the device has got yet another serial number, you can see that in the picture: "sdm3055_systeminfor_2.jpg"
So right now the system says about serial number
SDM30CA3160881 while the label on the back panel has
SDM305C3140046. What is the serial number of my device then?
How the Siglent company can be so unproffesional with its service? It seems to me that the service does not check the basic parameters and functions and safety (!) of the device being repaired. If it did, I would not have received my device in such shape.
Due to all of these I do not believe in my device measurements any more.
How about my warranty? It was issued to my original serial number, is it still valid for the device I have now? I also expect the warranty to be prolonged since I could not use my device for a long time from July 4 to October 20, 2016.
The last email I received from the service siglent was dated 20.10 2016:
„Hi Wojtek?
Was the problem fixed?
Awaiting for your reply.
Best regards,”
(sic!)
This is what I wrote above is also sent to the Siglent service (24.10.2016).
I did not receive any more response by present day.
I must admit that I am really disappointed with the quality of the Siglent service.
