Water Safety Kit (WSK)
3 The upper display shows the conductivity
reading and the lower display sequentially
shows calibration standard values 84µS,
1413µS & 12.88mS if the measuring
range of the tester is set to
AUTO .
4 Rinse the electrode with the calibration
standard that you intend to calibrate and
then dip the electrode in the other beaker
with same calibration standard. Swirl
gently to create a homogenous sample
and allow time for the reading to stabilise.
5 Press HOLD/ENT key to confirm the
calibration. LCD shows ‘CO’ for 2 seconds.
6 For multi-point calibration, the tester
goes to the next calibration point. Rinse
the electrode in de-ionised water and
repeat step 4 & 5 with next calibration
standard solution.
Manual Calibration
1 Make sure the tester is in measuring
mode. Rinse the electrode with the
calibration standard that you intend to
calibrate and then dip the electrode in
the other beaker with same calibration
standard. Swirl gently and allow time
for the reading to stabilise.
2 Press INC or DEC key to enter calibration
mode. The ‘CAL’ indicator appears in LCD.
3 The upper display shows the measured
conductivity reading of the solution
based on previous calibration (if any) and
the lower display shows the default
(uncalibrated) conductivity reading.
Note: The tester shows error message ‘Er.1’ :
(a) If the reading is over range (Or) of
selected measuring range of the tester, or
(b) If the default (uncalibrated) reading is not
within the acceptable calibration standard
range. Use
INC and DEC keys to adjust the
upper display to the correct conductivity
value of the calibration solution.
4 Wait for 5 seconds for the tester to
automatically confirm the calibration
by displaying ‘CO’ and return to the
measurement mode.
8.3.6 Temperature Calibration
Temperature calibration need not be performed
every time, unless the temperature reading
differs from that of an accurate thermometer.
If temperature calibration is performed,
Conductivity calibration is mandatory.
1 Make sure the tester is in measuring
mode. If required, press
°C/°F key to
select the desired unit of measurement
for temperature (Celsius or Fahrenheit).
Dip the tester into a solution of known
temperature and allow time for the
temperature reading to stabilise.
2 Press INC or DEC key to bring the tester to
the calibration mode. ‘CAL’ indicator appears
in LCD. Immediately press °C/°F key to
switch to the temperature calibration mode.
3 The upper display shows the measured
temperature reading based on the last
set offset (if any) and the lower display
shows the default (uncalibrated)
temperature reading based on factory
settings. Use
INC and DEC keys to adjust
the upper temperature reading to the
known temperature value of the solution.
4 Wait for 5 seconds for the tester to
automatically confirm the temperature
calibration value by displaying
‘CO’ and
return to the measurement mode.
8.3.7 Changing Batteries
Replace the batteries when the low battery
indicator starts blinking.
1 Open the battery compartment lid
(with attached lanyard loop).
2 Remove old batteries by pulling plastic
ribbon. Replace with fresh ones.
