Watts VIEW com Changing the Voltage monitoring range of your WattsVIEW sensor The WattsVIEW sensor can monitor from zero to 200 Volts which may not be your desired range Below you will see R1 and R2 which form a 41 to 1 Voltage divider so that when 200 Volts is present at the input of the Voltage monitoring Green connector below the PIC microcontroller only sees 4 6 Volts Since this 1s such a wide range the resolution of the Voltage measurement is only good out to one digit of precision Example With an 8 bit Analog to digital conversion capability of the PIC 2 8 gives us 256 counts to measure 200 Volts Dividing the range by the counts we get 200 256 0 78 Volts resolution If you want to improve that resolution for lower Voltage measurements the best resolution you can get is 0 1 Volt by changing R1 from 150kQ to 18kQ which performs as a 5 to 1 Voltage divider with a resoultion of 256 Counts 30 Volts 0 1 Volts Digikey part number CF14JT18KOCT ND costs about 0 10 and is easy to install if you have a soldering iron Please contact us if you would like us to make the custom modification After you change the resolution you will need to recalibrate the WattsVIEW sensor as shown in this YouTube video https www youtube com watch v nW XPmwbHCa4 You can also find this video link by going to http wattsview com and click on downloads Look in the Configuration Utility section R2 RES 3 6K OHM 1 AW 196 AXIAL Digikey
