SALT CALIBRATION
Fo llow the below steps for salinity
c alibration:
1. Insert the probe into demineralized
or distilled water for about 30 minutes
to rinse the probe.
2. Select the Sodium Chloride standard
for calibration. 10~40ppt is suggested.
3. Pour 4 cm (deep) of the standard into
two separate & clean containers.(A&B)
4. Turn on the meter. The full LCD will
flash three times. Press the MODE
key to switch to SALT mode.
5.Rinse the probe in one of the contai-
ners. Gently stir the probe. Rinsing
removes contaminants that affect
the calibration.
6. Dip the rinsed probe into the other
container. Tap the probe at bottom of
container to remove air bubbles. Let
the probe stabilize to the solution
temperature.
