Conductivity reading on
controller does not match
portable hand-held reading.
Conductivity reading is
within specification.
Due to variations in hand-held meters, conductivity
standard solutions, temperature compensation, and the
controller’s accuracy of +/- 2% of scale, the reading on
the controller may not match that of your hand-held
tester exactly.
