Customer Consulation
I bought your new Hantek LCR 1833C from Banggood.
It is a great meter, provides unique resolution, features and is the best in its price class x2.
I am using your meter for an industrial project and it failed after 11 days of use in a weird way that could be a software lockup or a usb-serial chip failure.
I am an EE with 50 years of embedded experience and regularly uses 32bit ARM chips so I know the symptoms.
During the 11 days of use I made around 1000 measurements turning the meter on for 20S and then off to prevent test device heating.
It never had an issue. However, after I setup the software for a PC interface and got it working with it all the normal keysight connection messages it stopped working after I shut it off. A meter failure after 1st use of the USB-PC software is rather odd. Btw, I used the new driver code for the ARM SN of 20201010 so that is correct.
I was testing the interface measuring a 285uh, 2.89 Q choke at 100khz for around 20 minutes checking every 5 minutes. attached is the photo of the working meter.The 1st anomaly I noticed while plugged into the PC is that the handset display went dark but the system continued to work normally. After I shut down the PC software and disconnected the USB, the meter never re-started. I tried plugging it in the USB was now not recognized preventing any access. I tried removing the batteries for a minute to see if I could create reset re-start but it had no effect. If you want I can do added testing to help define this issue for you.
However, I need another meter asap for my project. Banggood, Ali and Amazon show a 14 day lead time and then shipping times of a week or 2.
Which distributor has stock that I can buy immediately? Can you sell me one directly? I can supply a visa for payment.
Thanks for your help.
