Power_Measurements_Fluke289
Automated power consumption measurements using Fluke 289
This simple peace of software allows to read current values from Fluke 289 multimeter using serial port and plot a corresponding graph.
Flow of operation is the following:
- Send request to multimeter 'QM\r'
- Receive a response '1.0327E0,ADC,NORMAL,NONE' (where the only thing we actually need is floating point number 1.0327E0 which represents current value in Amperes)
- Add timestamps to each value
- Save measurements one by one to a file
- Read the file and plot a graph A(t)
Script can be called using python from CLI. Help option contains short descriptions of all options. Also, they are quite self explanatory in the code but I will mention them here just for convenience so that all info is gathered here.
usage: meaplotter.py [-h] [-f FILEPATH] [-p SERIALPORT] [-g GRAPHLABEL]
[-s SAMPLES] [-d DURATION]
optional arguments:
-h, --help show this help message and exit
-f FILEPATH, --filePath FILEPATH
path to the file where measurements are saved
-p SERIALPORT, --serialPort SERIALPORT
port on which Fluke 289 is connected
-g GRAPHLABEL, --graphLabel GRAPHLABEL
name of the graph
-s SAMPLES, --samples SAMPLES
N of measurements/second [0; 25]
-d DURATION, --duration DURATION
duration of measurement in seconds [10; 86400]NOTE matplotlib requires gcc, g++/gcc-c++, freetype, libpng to be installed
TODO
- would be nice to be able to install this tool as rpm package which will install necessary c/c++ and python libraries as well
