    I've had this combo pin for a month,and it works really well, but I have a question. Here is an example. I'm testing the storage liquid. When you cut it on you have 3 choices using the method button. ph pops up in top right corner and I get a reading of 6.34 simple enough. When you hit method button again you get a pop up in corner that says U S the storage liquid reads reads 46(I don't know what this reading means) When you hit method button again the ppm pops up at top and reads 19 again simple enough. So what is the U S reading I'm getting???

    It doesn't read us it read a weird u with long line off u, correct? That is the ec reading.

    Direct from hanna it is the EC reading.

    I have the same meter and I think the u s is another form of reading TDS like PPM. I think Europe uses this much like how we use quarts opposed to liters and there are multiple ways on how it's calculated depending on conversion factors. the manual describes this but I wouldn't worry about measuring the storage liquid but be sure to use it and not let the ph probe dry out
