START
Select 1
0% out --> "25%" representing 250 g/l
100% out --> "32%" representing 320 g/l
(g/l display not supported, so here using % instead. Also
display is XX.X%, so we display actual concentration
divided by 10
Calibrate conductivity value using personal SC meter
(1) Set temp. compensation of both ISC202 and personal
SC meter to zero.
(2) Place both ISC202 sensor and personal SC meter sensor
in measured solution, wait for temperature and conductivity
readings to stabilize.
(3) When stabilize, calibrate by adjusting ISC202 reading to same as
personal SC meter reading.
(4) Finally revert temperature compensation to NaCl default.
Service Code 20
0% out -> 404 mS/cm
100% out -> 450 mS/cm
(These conductivity values apply to reference temperature)
