I purchased this meter and I can not figure out how to read EC and PPM without opening the back and manually pressing the black button. Is there a way to read PPM and EC without going through this? I use this meter to test my Hydroponic Solution and I do watch both readings. I like the meter, I find it very accurate from reading to reading... but I really wish I could read what I need with the press of a button.

Honestly, you guys should really add this information into your packet that comes with the tester… because it’s not in there and I had no idea how to set it up until I looked up videos on it!
