Where exactly does it say "440 10xUS" and do they use all lower case letters?

Here's what I can tell you...

EC is really measured in Siemens per meter (S/m) but some meters will display EC in microseimens per centimeter (uS/cm) or milisiemens per centimeter (mS/cm). What is often refered as EC is actually mS/cm, so to get that, you would simply divide the reading from uS unit by 1000.

The 10xuS MAY be indicating that you need to actually divide by 10 to get to microseimens (and by 10,000 to get to milisiemens).

Best bet, without firm instructions/help, is to take some readings from some calibration solution to see if you can understand what they're doing.

I have no clue about the "440"!
