Hey guys I have a grow gadgets budget ec meter and also some calibration fluid which has a EC of 1.417.
When I put the EC pen in the fluid it gives me 0.65 so i turned the screw at the back to calibrate it to up the value to 1.41 since this meter only has 3 digits so I am assuming 1.41 is what I should be reading however the pen only calibrates up to 0.92 and nothing higher.
the manual states it has ameasuring range of 0-9990ec with a resolution of 1ec.
am I doing something wrong or is the ec pen faulty? surely it should say 1.41 when in the calibration solution?
