 The web software is split into different parts as highlighted below. 
 i.  Extraction of zip file from Github.
 ii. Creating database.

-### Extraction of zip file from Github : 
- The web software can be replicated by any developer by downloading the zip code file from https://github.com/EnAccess/OpenSmartMeter/tree/main/Web%20software . after the code is downloaded, developer will need to host the web on a hosting platform.

 ## Calibration : 
 The meter calibration is done after the meter PCB component is fully assembled alongside exterior casing. 
 Step 1 : Calibrating voltage and current
 The design engineer proceed to calibrate the voltage, current. The voltage and current is calibrated by calculating the value measured by meter as compared to the true value measured by a test bench, the excel sheet available in the link provided below is used to calibrate the voltage and current by inputting the measured and actual values of voltage and current in the appropriate cell of the excel calculator.

 ### Note : A meter test bench is needed to know the true value of voltage and current to be calibrated into the meter.
