6. Operation

6.1. Measurement

Note: the instrument must be calibrated before reading
the first conductivity value.
1. Press
to turn on the instrument.
2. Remove the sensor protector.
3. Clean the sensor with deionized water.
4. Stir the sensor uniformly in the sample, holding it by
the top.

6.1.1. Stability measuring

Follow the diagram.
The reading is not stabilized on the screen until the
sensor signal varies less than ± 1 digit for 6 sec.
Once the reading has stabilized, the screen lights up
for 2 sec.

6.1.2. Continuous measuring

Once stability measuring has begun, press the
twice.
The instrument displays the measured value directly on
screen at all times.
The continuous reading should always be started after
beginning a stability reading (see diagram).
To end a continuous reading, press
The display will light up for 2 sec.
Note: If the measuring instrument is not used for 5 minu-
tes, it will shut off automatically.
6.2. Changing measuring units
(EC/NaCl/TDS)
To change the units of measurement from con-
ductivity (EC) to salinity (Sal/NaCl) or to TDS,
or vice versa.
