TH2830 vs TH2832

<< < (7/74) > >>

KungFuJosh:
Here's totally random thought.

If you're looking for an awesome lab grade LCR meter, the 2830 or 2832 are both great devices. The hardware and build quality are well done.

However, I've had two very different experiences when it comes to support and communication. Tonghui's support was slow, if they responded at all (and they usually did not). They also ignored any requests for firmware of either version, including the version I already have with their name on it. On the other hand, Sourcetronic got back within 1 business day every time I emailed them, and they responded to my first request for the firmware, with the firmware. What I'm saying is, if you have the choice between purchasing the ST2832 or TH2832, I would get the Sourcetronic version without hesitation. You can simply expect better support.

On a totally unrelated note, see the random file attached. 😉

KungFuJosh:
My first experiment was an expected successful fail. 😉

When the LCR first starts up, hold down the TRIG button to enter setup.

I renamed the firmware file as CURRENTMODEL.SEC (th2830.sec), and loaded it on a USB stick inserted on the front of the meter.


Select option A: for Firmware Update:


And, sadly, as expected, it shows the "Wrong Firmware!" warning I copied from the hex code above:



To revert it back, I renamed the original th2830.sec file with the  "other" model's number, and that restored my TH2830 back to normal.


I'm guessing we might find success if somebody can figure out the hardware IDs inside the firmware.

nctnico:
Can you also get the ST2830 firmware?

Martin72:
Ah, not bad thought... ;)

Could ask sourcetronic if there is firmware for our ST2830 avaible*...

*)Asked them for a service manual..no way.

Once again, the ST people win. I just asked and they sent it. Weird.
