4. MEASURING PROCEDURE 4-1 Measurement Consideration White mark on the up position of " Testing Bottle " White mark on the edge of the " Container " Fig. 2 1) There is a " White mark " on the edge of the " Container " ( 3-2, Fig. 1 ) and also on the up position of " Testing Bottle " ( 3-10, 3-11, 3-12 3-13, 3-14 Fig. 1 ), refer Fig. 2.
3) Insert the " Testing bottle " to the bottom of " Container " ( 3-2, Fig. 1 ) completely. 4) Before the measurement, it should envelop in the " Cover " ( 3-1, Fig. 1 ) completely. Remark : Before the measurement, it should keep the outside of Testing Bottle under the dry condition and without existing any dust. 4-2 Measurement Before the measurement, should select the measurement model to " Free Chlorine " or " Total Chlorine " first, the setting procedures refer to chapter 4-3, page 8.
3) Insert the " Testing bottle " to the bottom of " Container " ( 3-2, Fig. 1 ) completely. Before the measurement, it should envelop in the " Cover " ( 3-1, Fig. 1 ) completely. 4) Press " Zero Button " ( 3-7, Fig. 1 ) once, the display will show the text " tESt " ( TEST )" with flashing, then show " 0.00 ". Liquid with the DPD powder 5) Take away the " Testing bottle " with the measurement liquid away from " Container " ( 3-2, Fig. 1 ).
6) Wait one minute approximately, then insert the " Testing bottle " to the bottom of " Container " ( 3-2, Fig. 1 ) completely. Before the measurement, it should envelop in the " Cover " ( 3-1, Fig. 1 ) completely. 7) Press " Test Button " ( 3-5, Fig. 1 ) once, the display will show the text " tESt " ( TEST )" with flashing, wait approx. 10 seconds, the Display will show the measurement value.
4-4 Data Hold During the measurement, press the " Hold Button " ( 3-4, Fig. 1 ) once will hold the measured value & the LCD will 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.
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.
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.
* 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.
* 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.
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.
