Measurement
1. Short press /MEAS to turn on the tester. Rinse probe
in distilled water and dry it gently with a clean tissue to
remove excess water.
2. Stir the probe in the sample solution gently, leave it to
stand. Wait for the stability icon () to remain on, then
take a reading.
3. Rinse off the tester thoroughly in distilled water after
each test.
Notes:
• This salinity tester measures practical salinity converted
from electrical conductivity (NaCl concentration). It does
not measure absolute salinity.
• The unit has already been calibrated after manufacture.
User can use the tester immediately or can test it in the
calibration solutions to test its accuracy. If error is large,
calibrate the tester before using.
• We recommend replacing the calibration solution after
5 to 10 calibrations to maintain accuracy.
Setting the Parameters
When tester is off, long press /MEAS to enter setup mode.
Short press
press CAL/ and parameter will flash, then short press
/MEAS to choose desired parameter. Short press
CAL/ to confirm parameter selection. Long press
to return to measurement mode.

Notes:
• Select “Yes” for P3 to restore the calibration to the
theoretical values and parameter setting to original
values. When tester’s calibration or measurement
performs abnormally, this function can be adopted
so the tester returns to factory default setting and then
users can conduct calibration or take measurements
again.

Battery Installation
The tester uses four AAA batteries. Please install batteries
according to the following steps. Note the correct direction
of battery installation: the positive side (+) of every single
battery must face up. Incorrect installation of batteries will
cause damage to the tester and create a potential hazard.
