# ut61e

Stream interface for the UNI-T UT61E multimeter.

Requires the `he2325u` and `es51922` command line applications.

You can find a fork that fixes a Linux USB reset problem [here](https://github.com/bergos/ut61e_cpp).

## Usage

The module returns the UT61E class.

A measurement stream can be created by creating a new instance of the class.

The path to the `he2325u` and `es51922` must be provided in the options.

    var UT61E = require('ut61e')

    // creates a new instance

	var ut64e = new UT61E({

	  he2335u: {

	    // path to the command line application

	    path: '/home/bergi/Projects/c/ut61e_cpp/he2325u/he2325u'

	  },

	  es51922: {

	    // path to the command line application

	    path: '/home/bergi/Projects/c/ut61e_cpp/es51922/es51922'

	  }

	})

	ut64e.on('data', function (chunk) {

	  // writes the measurement objects to the console

      console.log(chunk)

    })

    

## Measurement object

The measurement object contains the following properties:

- `timestamp`: The number of milliseconds since 1 January 1970 00:00:00 UTC 

- `sequence`: A sequence number that starts at 1 after connecting to the device or parameter changes on the device

- `value`: The measured value

- `unit`: The unit of the measured value
