Excitation voltage limits not working

Hi, Iam a begginer with the dewesoft software and hardware so I may be missing something.


When I create a sensor like in the first picture and set min and max excitation voltage and save (I have to click edit and save multiple times for it to start working) I can only set the excitaion voltage in the min max range as expected when the sensor is assigned to a chanel.


But the issue is, when i relload the configuration, the sensor is still assigned and the min max voltages are still in place, but i can set whatever excitation voltage i want regardless of the excitation limmits.


Is this some kind of a bug or am I missing something?

Thanks for help.

If you want to lock your excitation at 5v, select 5 as your excitation then check the "lock all channel settings" button from the edit sensor panel. This locks the amplifier settings including the excitation.



If you want to allow a range of excitations then UNCHECK lock all channels and CHECK the sensor excitation min/max check box and give those fields a range (Min/5 Max/10 for example). This allows you to change the excitation on the amplifier side, but only within the range specified in the sensor settings.

@Lemmy Atom

I did what you suggested in the second paragraph and it worked until i reloaded the setup. Even tho i saved the settings for example exactly like in your second screen, i was able to set the excitation voltage to anything like 15V.


I was told that it is a bug and it has been reported.

I’ve run into similar issues with excitation limits not behaving as expected, and your notes make things much clearer. Double-checking the channel config and firmware version seems to help.

@Sam Daniel

I've discussed it with an employee from Dewesoft and it's a bug and ticked has allready been created so it will be hopefully fixed in upcoming versions.

Dear all. The solution will be included in the next version 2025.3 coming this year.

The solution is also already included in the latest release candidate you can get here:
