Firmware mod for GWInstek GPP series lab bench power supply

[Pr Utser]

@Cavhat,

Thanks for reporting this issue. While trying to reproduce I found that the web server interferes with the measurement readouts. Luckily there is an easy fix for it. The bug will be fixed in mod release 1v03 which I will post next.

@Pr Utser

Hello, I have a GPP-1326, this firmware can be directly upgraded to GPP-1326？？？

Hi @Wade2019,

I have not tested the mod on a GPP-1326 myself but I see no reason why it would not work.
The mod has been developed to support all GPP-x32x models.
Personally I tested it on a GPP-4323 with LAN option but without GPIB option.

Maybe others could comment on what they are using.
