b. Enter the known conductivity for Pt. 1 in uS/cm. Press ENTER.
c. Complete this process for additional known data points. Press ENTER.
CALC CUST appears briefly.
d. Press ENTER.
PROCESSING appears briefly; then APPLY CUST appears.
e. Press ENTER to register the custom curve into memory and return to the SETUP
