Python library for reading data from the DER EE DE-5000 LCR meter.

• Debian/Ubuntu

   $ sudo apt-get install python3 python3-pip
  

• macOS with HomeBrew (tested on macOS 10.14 Mojave)
  Install HomeBrew:

   $ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  

  Install Python3:

   $ brew install python3
  

see pySerial Docs

• Debian/Ubuntu

   $ sudo apt-get install python3-serial
  

• macOS

   $ python3 -m pip install pyserial
  

The LCR meter transmits data via its IR port. You'll either need the original IR-to-USB Adapter or build your own.
An example for how build your own adapter can be found here: IR-to-USB Adapter for DER EE DE-5000 LCR Meter

The cli_de5000.py script is run from command line using the following command:

$ python cli_de5000.py COM_PORT

where COM_PORT is the name of serial port where your IR receiver is connected.
Linux: e.g. /dev/ttyUSB0, /dev/ttyUSB1, ...
Windows: e.g. COM1, COM2, ...

To output the data from the meter to a CSV file:

$ python cli_de5000.py --csv FILENAME COM_PORT

To see all available options:

$ python cli_de5000.py --help
