This code is able to be utilized for controling differential mobility analyzer (DMA) and condensation particle conuter (CPC) which is known as scaning mobility particle sizer (SMPS, a particle size distribution measurements in gas). This code works with GUI as desplayed in this figure.

1. Download binary file DMACPC.exe from here or email to us (the address is at the bottom of this page) if you don't have an access.
2. Download NI-DAQ driver from here and install it (it just follow their instruction).

1. Double click DMACPC.exe file
2. Set the device name and port to use. Default value is Dev1/ai0 for the reading from CPC and Dev1/ao1 for sending control signal to high voltage source. Device name is obtained from "NI Device Monitor" when the device is connected to your PC via usb cable.

• For Anaconda user (you can get Anaconda from here) Most of labraries are installed for Anaconda user case but you only need to download NI-DAQ driver from this link. After the installation, you can run HV.py from any console like Powershell Prompt or JupyterLab.
• For not Anaconda user You need to install the modules if it isn't: Numpy, Tkinter, Matplotlib, and NI-DAQ driver, then you can run HV.py. Here, the explanation is brielf since "not Anaconda" user may know a lot how to install and use it.
