Sorry, I attached wrong file.
 

Hi Andrea,
Thanks for your support.

Today (01 Oct) I've just update my DMM6500 from 1.7.12b to 1.7.14j firmware.
After updated to new firmware, I try to run several times turn on/off my unit, but I can't reproduce this issue.

I will update infor if I can reproduce it on 1.7.14 version.

Keithley DMM6500 - random jump touch issue
Dear everyone,

My unit was bought from Jan 2023 (from EMIN dealer in Vietnam.)
Running firmware 1.7.12b version.
Serial number:  04576280
This issue only appear around 1-2 month recently.
Unfortunately, until now (Sep 2024), my warranty was expired.

I recorded issue, please refer it for more detail.
(Sorry for not very good my video quality & and annoying sound from continuous failed).

I double that this issue may be a firmware issue, because I still can touch to all button.
But just some seconds later, it often "random" jump to "Cont" mode or "Diode" mode, "Digi V", "Ratio" mode...
If it's a firmware issue, I hope this issue can be fixed in some next firmware release.

In my point, I think it will be better for customer if have more option in System Setting.
- Option "disable touch" feature, and support external USB mouse via USB port on the front this product.
This option help customer can use USB mouse as they want.

If you have any idea, please let me know.
Thanks.
