How to read the EC Tester:
The electronic display on the EC pen requires a factoring of 100. Easiest way to use this is to pretend there is a decimal place before the 3rd Therefore, if you see the number 150, that means there is an EC 15.0 (Way too high!) If you see 015, that means you have an EC 1.5 (Perfect). 001 = 0.1 EC and so on…. The EC Pen generally will not read if the EC is above 20.0, therefore if you see a weird reading, it’s likely the EC is too high to be read properly by the pen. So add more water and re-test…..
Remember to pull the plastic tab out from under the batteries before the very 1st use.
