Truncheon Meter Readings

hey guys as the title says im just wondering whos has one of these meters,and what are the clone-veg-flowering ec readings they use that they find perfect for growing,i use the cf side for 1.6-1.8 in veg and -2.0-2.2 for flower,tho that doesnt seem to spot on,i seem to be having nute problems,any sugestions? in ppms thats between from 1120-1540,does that seem to high?
heres a pic of the meter, i just hear alot of peeps talking about 8-900ppm?

theres 2 ppm's cfx500 and cfx700.
