in the sample.
From measurement mode:
1. Press the MODE key to select mg/L (ppm) mode.
2. Press the SETUP key to enter SETUP mode.
3. Press MI/ or MR/ keys to scroll through main
groups until you view parameter “dPr” in the upper
display.
4. Press the ENTER key five times. The upper display
shows the salinity value and the lower shows SAL.
5. Press MI/ or MR/ keys to enter the correct
salinity adjustment factor. The salinity adjustment
factor range is 0.0 to 50.0 ppt.
6. Press the ENTER key to confirm selection and to
move back to main group “dPr”. If you want to
return to measurement mode, press CAL/MEAS.
