Scaling the Measurements

• ScanEngine Explorer Script
• New Variable well init
• New Variable booster init
• >Assign RepeatTimer = 6
• Repeat
• >Assign IP = 192.168.2.252 //PIC board
• >Assign HTTPPage = jsdata.cgi
• >Assign HTTPSitename = "Well Monitor"
• >Assign HTTPUsername:Password = admin:pw
• Fetch
• If HTTPReplyCode == 200
• // process received data
• // normalize pump circuit current to amps
• Assign well = 0.007166667*Object.AdcValues0
• Assign booster = 0.007166667*Object.AdcValues1
• Else
• // no data received
• EndIf

• Define script variables for measured AdcValues for well and booster pump currents

• Scale the AdcValues to current in amps
• The measured values may be properly scaled to current (A), or apparent power (VA)

• With a web page scraping script defined for the name of our fetched page (jsdata.cgi), our script can reference (with “Object.” suffix) the scraped data
