UT-READER - a PC tool for UNI-T multimeters

Read measurements from the multimeter in real time.
Print the data in different formats.

This tool is primarily designed for the ut800 series, but it might work with other models.
The code inspired by https://github.com/tmatejuk/ut804_linux_logger

Supported platforms: Linux, MacOS

Build and install

make && sudo make install

Usage

ut_reader -d /dev/ttyXXX <options>

-d - Set the serial device name, it might be RS232 or USB converter

Available options:

	-b <baud> - Set baud rate, default is 2400
	-f <format> - Set custom date format, default is %Y-%m-%d %H:%M:%S
	-u - Use Unix timestamps instead of date/time
	-c - Print data in CVS format
	-v - Don't print data units

CVS output example:

ut_reader -d /dev/ttyUSB2 -c
Serial device /dev/ttyUSB2 with baud rate = 2400
