In other words, if yours uses the .50 and the other guy's meter is .70, devide his by 700 for EC and multiply the EC by 500 for your meter's target reading.
Ex. The other guy's reading is 1280 and his is a .70 meter and yours is a .50 meter.
1280PPM / 700 factor = 1.83EC
1.83EC x 500 factor = 915PPM
-OR-
You could simply divide the .7 factored meter's reading by 1.4 to get the .5 factored meter's target reading:
1280/1.4=914.29. Close enough to not matter a bit.
To go the other way, you would multiply the .5 factored meter's reading by 1.4 to get the .7 factored meter's target reading:
915*1.4=1281 again, close enough to not matter.
Wow this is great info, copy and pasted. Thank you.
How do I find which conversion method my meter takes? I searched the packaging and the Google and nothing on how it does it, unless I'm not reading something right.
