I just purchased a siglent SHS810 and I am regretting it worse than that hantek DSO purchase I made earlier. The multimeter section of the siglent is totally screwed up out the box. The scope portion is working but the meter section is locked up. In meter mode the value of 1.0 is locked on the screen, no i do not have the unit in stop mode. The unit is stuck in manual configuration on the measurements and continuity checker is constantly latched. I can not take a single measurement because the whole multimeter is locked. I upgraded the firmware and it has the same issue. When I can manage to scroll to DC current measurement the number 1 keeps randomly flashing.
My Faulty Siglent SHS810
Russian Guy Faulty ShS806
Update
After a back and forth with a stumped Siglent technical support who encouraged me to disassemble the unit for the record and reseat the multimeter module which did not solve the fault, the real solution for my problem came from a third party on how to fix the scope. The problem I was having with the Shs810 was not isolated to my scope or even the model. Another user from Russia with a Shs806 discovered that the crystal clocking the multimeter module on his scope had a cold solder joint. Examined my shs810 and discovered the same thing. I retouched the joints and the shs810 has not acted up since.
During my closing emails from SIGLENT China the best they would do for me is replace my shs810 100mhz scope with a shs806 60mhz scope because they had no available shs810, now does that make any sense. The Siglent tec tried to convince me that going from a 100mhz band to a 60mhz band after I freckin paid for the 100mhz band is not a down grade and no I was not offered back the difference in price.
Bottom line is Siglent as a company did not solve the problem, a problem that was a result of their manufacturing. As a result of horrible customer service I will never buy from Siglent again. If you buy Siglent make sure you can return it to the seller if it goes bad on you and pray that if it does go bad it does so in the return window because beyond that you are at the mercy of Siglent warranty and their mentality with me with a product I bought defective out the box was "you got a bad brand new unit fix it your damn self" which is what happened
Also be warned of the re branded version of this product line being made for BK Precision. Models 2511, 2512, 2515 and 2516. Your only hope here is if things go bad within the warranty period since it is a BK branded product than BK will actually honor the warranty.
