A/m how are you doing bro I have just done the calibration thing with the distilled water and the salt and the truncheon is reading 1.2 to1.4 and the other meter is saying 502 x10 flashing at the corner of the 502 reading does this mean they are both out thanks in advance and again for the help peaceIf you do take DISTILLED water and put 1 gram of TABLE salt in it... mix well and test... 500 scale ppm meter should read 1000ppm EC should read 2.0
