4. MEASURING PROCEDURE
4-1 Measurement
Before the measurement, you should set the
measurement mode to " Free Chlorine " or " Total
Chlorine ". For setting procedure, refer to chapter
4-3, page 8.
1) Power ON the meter by pressing the Power Button once.
The display will show " Free ( TOTAL ) " for approx. 1 second.
then show " CAL 0 ". The meter is now ready for the ZERO
setting procedures.
2) Fill the measurement liquid into the testing bottle.
Note :
Be sure to fill the
testing bottle to the
top of the 10ml line.
3) Open the test camber cover and insert the testing
bottle into the test chamber. Make sure the testing
bottle is seated fully and oriented correctly. The
white mark on the bottle should point towards the
white mark on the test chamber. Close the cover.
Note :
Be sure orient the
testing bottle into
the test chamber
correctly.
ZERO setting for the liquid

4) Press the Zero Button once, the display will flash
( TEST ) , then show " 0.00 ".
5) Open the test chamber cover and remove the testing
bottle.
6) Open the testing bottle an add the DPD powder to the
testing bottle. Shake the bottle for at least 10 seconds.
Note :
•For the Free Chlorine measurement, it should
use the " Free Chlorine DPD powder ".
•For the Total Chlorine measurement, it should
use the " Total Chlorine DPD powder ".
7) Wait approximately one minute, then insert the
testing bottle into the testing chamber.
8) Press the Test Button once, the display will flash
( TEST ) , wait approximately 10 seconds, then the
display will show the measurement value.
After the testing, you should wash the

select the Free Chlorine function.
•Fortheindustrialwaterpollutionapplication,
typical to select the Total Chlorine function.
4.3 Data Hold
1) During the measurement, pressing the Hold Button
once will hold the measured value & will display a
HOLD symbol.
Note: Press the Hold Button once again will release the
data hold function.

4.4 Data Record ( Max. , Min. reading)
Note: The data record function only records the
maximum and minimum readings.
Press the REC Button once to start the data record
function and there will be a REC symbol on the
display.
While REC function is active:
1) Press the REC Button once, the REC MAX symbol
along with the maximum value will appear on the
display.
Note: If you want to delete the maximum value, press
the Hold Button once, then the display will return to
the REC symbol only.
2) Press the REC Button again, the REC. MIN symbol
along with the minimum value will appear on the
display.
Note: If you want to delete the maximum value, press
the Hold Button once, then the display will return to
the REC symbol only.

5. CALIBRATION PROCEDURE
1) The meter can be calibrated under following calibration
points :
•Zero
•1.00 ppm
•Zero
•1.00 ppm
Note : The calibration procedures for the function of " Total
chlorine " and the " Free chlorine " are independent.
2) Calibration requires the following two solutions :
•Zero Chlorine standard solution
•1.0 ppm standard solution ( Free or Total ).
3)
1) Turn the meter on.
2) Press and hold the CAL button until CAL appears
on the screen.
3) Let go of the CAL button. The screen will
display 0.00, prompting for the Zero standard
solution.

4) Place the Zero standard bottle into the test
chamber, lining the vertical white line of the bottle
with the white dot on the meter. Close the lid and
press the TEST/CAL button once. The meter will
flash the word CAL on the screen for up to ten
seconds.
Note: If the zero calibration was successful, the
meter will stop blinking and display the number
1.00, prompting for the 1.00 ppm standard
solution.
5) Place the 1.00ppm standard bottle into the test
chamber, lining the vertical white line of the bottle
with the white dot on the meter. Close the lid and
press the TEST/CAL button once. The meter will
flash CAL on the screen for up to ten seconds.
Note: If the calibration was successful, the screen
will stop blinking and display 0.0, indicating that it
is ready to test samples
6. BATTERY REPLACEMENT
1) When the left corner of LCD display shows , it is
necessary to replace the battery. However, in-spec.
measurements may still be made for several hours after low
battery indicator appears before the instrument become
inaccurate.
2) Open the Battery Cover by unscrewing the cover and slide
the Battery Cover away from the instrument and remove the
battery.
3) Replace with DC 1.5 V battery ( UM4, AAA, Alkaline/heavy
duty ) x 6 PCs, and reinstate the cover.
4) Make sure the battery cover is secured after changing the
battery.
