display a " HOLD " symbol.
* Press the " Hold Button " once again will release the data

hold function.

4-5 Data Record ( Max., Min. reading )

* The data record function records the maximum and

minimum readings. Press the " REC Button " ( 3-8, Fig.
1 ) once to start the Data Record function and there
will be a " REC. " symbol on the display.

* With the " REC. " symbol on the display :

a)Press the " REC Button " ( 3-8, Fig. 1 ) once, the "

REC. MAX. " symbol along with the maximum value
will appear on the display.

b)If intend to delete the maximum value, just press

the " Hold Button " ( 3-4, Fig. 1 ) once, then the
display will show the " REC. " symbol only & execute
the memory function continuously.

5. CALIBRATION PROCEDURE

1)The meter can be calibrated under following calibration
points :

Free chlorine

*Zero
*1.00 ppm

or

Total chlorine

*Zero
*1.00 ppm

2)The meter ship along with

* Zero Chlorine standard solution ( CL-01 ) X 1 PC,
* 1.0 ppm Free Chlorine standard solution ( CF-01 ) X 1 PC.
* 1.0 ppm Total Chlorine standard solution ( CT-01) X 1 PC.

as the standard accessories.

3)The complete calibration should be executed by
following two solution :

*Zero Chlorine standard solution
*1.0 ppm standard solution ( Free or Total ).

10

4) Zero chlorine calibration
* Insert the " Zero Chlorine standard solution into the

" Container " ( 3-2 , Fig. 1) and envelope in the " Cover "
( 3-1, Fig. 1 ) completely, other procedures please
refer to chapter 4-1, 4-2.

* Press " CAL Button " ( 3-5, Fig. 1 ) continuously

until the Display show the text " CAL " then release
the button.

CAL

ppm

* During the display show text " CAL ", press the

" CAL Button " ( 3-5, Fig. 1 ), the display will show

0.00

CAL ppm

Now the meter is ready for the " Zero Chlorine "
calibration

11

* Press " CAL Button " ( 3-5, Fig. 1 ) once, the

Display will show following text with flashing ( approx.
10 seconds ).

flashing

CAL

0.0 ppm

Then the Display will show :

1.00

CAL ppm

Now the meter is finished the " Zero Chlorine "
calibration procedures and ready for " 1.00 ppm "
calibration procedures.

5) 1.00 ppm calibration

Refer to page 12, when finish the " Zero Chlorine "
calibration procedures and the Display show

1.00

CAL ppm

The meter is ready for " 1.0 ppm " calibration.

12

* Insert the " 1.0 ppm standard solution into the

*

*

" Container " ( 3-2 , Fig. 1) and envelope in the
" Cover " ( 3-1, Fig. 1 ) completely, other
procedures please refer to chapter 4-1, 4-2.

Press " CAL Button " ( 3-5, Fig. 1 ) once, the
Display will show following text with flashing ( approx.
10 seconds ).

flashing

CAL

1.00 ppm

Then the LCD display will return to normal
measurement screen, now the meter is finished the
calibration procedures ( Zero, 1.0 ppm calibration )
completely and ready for the measurement.

Remark :

The calibration procedures for the function of " Total
chlorine " and the " Free chlorine " are independent.

The complete calibration procedures for the function
of " Free chlorine " measurement should be
executed by

Zero Chlorine standard solution

1.0 ppm Free standard solution

The complete calibration procedures for the function
of " Total chlorine " measurement should be
executed by

*Zero Chlorine standard solution
*1.0 ppm Total standard solution

6. BATTERY REPLACEMENT

1)When the left corner of LCD display show " ", it

is necessary to replace the battery. However, in-spec.
measurement may still be made for several hours after
low battery indicator appears before the instrument
become inaccurate.

2)Loss the " Battery Cover Screws " and slide the
" Battery Cover " ( 3-9, Fig. 1 ) 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.
