| 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？？？ |
| Pr Utser:
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. |

@Pr Utser, thank you for this amazing mod! One question about calibration arising from the instructions: Step 5.j says to repeat measurements with a 20V setpoint voltage. That's suitable for CH1 and CH2, but what about CH3 and CH4? |
