Hi,

I am using the CS548 with with the CS302 Multichannel Install (5.05.34) on Windows 11.

Channel B on the UI is continuously increasing, and I have lost control on the Volts/Div. Additionally, the volts/div settings are not appropriate. The other channels are okay.

Referring to another post (https://cleverscope.com/topics/523/after-some-time-scale-dev-is-increasing-automatically/), the .ini file is present, and the Tahoma font is installed.

Could you please recommend ways to fix this? Screenshots attached.

Thanks

Hello Pradhar,
I am out at the moment, but this is a known mouse wheel problem. We have a solution coming along.

Please close the application, and open the ini file. You should find an entry along the lines of scroll wheel enable equals true. Change it to false and save. Close the ini file, and reopen the app. Do a Fit on the channel axis. Let me know if everything works again.

I edited the ini file. The scroll flag was indeed true, and I changed it to false, however the units have not been restored to the correct value. This is the configuration:

[Cleverscope4 x64]
HideRootWindow=True
appFont=""Tahoma" 13"
dialogFont=""Tahoma" 13"
systemFont=""Tahoma" 13"

[MAC]
Show = 1
Allow editing = 0

[Chart]
MaxChartFileChunkSize = 90

[Maths]
nChannels = 6

[ControlPanel]
DisableAutoSet = False

[RemoteList]
URL = www.cleverscope.com/distribution/remotelist.txt

[MouseWheel]
Use = False

[Connection]
AcquireDelayA = 200
AcquireDelayB = 500

[TriggerCrossing]
nSamplesToSearch = 8

[Debug]
ShowFPS = False
ShowLogger = False
LogLimit = 20000
ShowWinMap = False
ShowExitLog = False
ExitStepDelay = 100 ; ms
ExitLoopDelay = 10 ; ms
CleanPrfOnExit = False
DisableUDP = False
DisableUSB_FTDI = False


I had to reinstall the application for it to be fixed.

Hi Pradgar,
Good you got it going. Re-installing is above and beyond.
Did you manage to click the Fit button on the Channel B axis? You will find the Fit button in the cluster of axis control buttons, 3rd button up, in your case the B channel axis controls are top right.

You can also save a file of a setup you like (File/Save As..) and then reopen it later to restablish the setup.
