8 Conductivity Calibration
PCE-PWT 10 pocket salinity tester allows up to 3 points calibration in the conductivity mode. To
ensure higher accuracy, we recommend that you perform 3 points calibration or select a standard
value close to the sample value you are measuring. The tester will automatically detect these
conductivity standard solutions and prompt the user to calibrate the meter. When the calibration
is done, all new calibration values will automatically override existing data. The following table
shows acceptable conductivity range of calibration solution for each measuring range.
MEASURING RANGE
CALIBRATION SOLUTION
RANGE
DEFAULT
0~20µS/cm
7~17µS/cm
10µS/cm
20~200µS/cm

700~1700µS/cm
1413µS/cm
2~20mS/cm
7~17mS/cm
12.88mS/cm
Ensure that you use fresh conductivity standard solution during the calibration. Do not reuse
calibration solutions as it may be contaminated and affect the calibration and accuracy of
measurement.

9 Single Point Calibration
1.1 Rinse the conductivity electrode with distilled water, then rinse with a small amount of
calibration solution.
1.2 Press CAL key, the tester enters the calibration mode.
1.3 Dip the conductivity electrode into the calibration solution, the tester immediately
shows current calibration standard (e.g., 1413µS/cm).
1.4 Press ENTER key, the default calibration value begins flashing.
1.5 Press CAL key to set each digit, press ENTER key to confirm. When the setting is
done, ensure the displayed value matches your calibration standard.
1.6 Press ENTER key to start the calibration. Wait for the reading to stabilize, the display shows

point is done, the display will immediately show “CAL3”. The tester prompts you to
continue with third point calibration.
2. Repeat the above steps until the display shows “END”, the tester returns to
measurement mode. Calibration is completed.
 Performing the conductivity calibration will simultaneously calibrate the corresponding
salinity value.
12 Temperature Calibration
During the measurement, if the temperature reading displayed differs from that of an accurate
thermometer, you need to calibrate the tester.
1. Press and hold the CAL key for 3 seconds to enter setup menu.
2. Press ENTER key until tester shows the “oC/CAL” or “oF/CAL”.
3. Press CAL key to enter the temperature calibration mode.
4. Press CAL key again to set temperature value (Resolution: 0.5oC).
5. Press ENTER key to confirm, the display shows next option.
6. Press MEAS key, the tester returns to measurement mode. Calibration is completed.
EXIT THE CALIBRATION:
During the calibration process, press MEAS key, the tester will return to measurement mode.

13 Switching the Measurement Mode
In the salinity mode, press ENTER key until the display shows “COND”. The tester now enters
conductivity measurement mode
Press ENTER key again, the tester returns to salinity mode.
14 Measurement
Rinse the electrode with distilled water. Dip the electrode into the sample solution. Stir the tester
gently. Wait for the reading to stabilize and record the measured value on the display.
15 Hold Function
PCE-PWT 10 pocket salinity tester contains two data hold modes. When the Auto-Hold function
is enabled, the tester will automatically sense a stable endpoint reading and freeze it, “HOLD”
indicator appears on the display. If the Auto-Hold function is disabled, press HOLD key, the
tester will immediately freeze currently displayed value. Press the key again to resume
measuring.
16 Electrode Care and Maintenance
● After each use, the conductivity electrode should be rinsed thoroughly in deionized water.
● If there is a build-up of solids inside the measurement area of the cell, these should be
removed very carefully with a cotton bud soaked in solvent, taking care not to touch the
metal parts of the inner cell.

17 Electrode Replacement
When the tester fails to calibrate or gives fluctuating readings for calibration standards, you will
need to replace the electrode module.
Twist the electrode collar counter clockwise, pull the old electrode module away from the tester.
Align the slot on the new electrode module, gently push the module into the tester.
Twist the electrode collar clockwise until it is tight. Installation is complete.
18 Replacing the Batteries
If the battery indicator is disappearing during use, you will need to replace the batteries.
1. Twist the electrode collar counter clockwise, pull the electrode module out from the
tester.
2. Insert two “AAA” batteries into the battery compartment, note polarity.
3. Align the slot on the electrode module, push the module into the tester. Twist the
electrode collar clockwise until it is tight.

24 Disposal
For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament
applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.
If you have any questions, please contact PCE Instruments.
