CALIBRATION PROCEDURE

1. The meter can be calibrated under the following calibration points:
   Free chlorine
   * Zero

• 1.00 ppm
  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 solutions:

• Zero Chlorine standard solution

• 1.0 ppm standard solution ( Free or Total ). 4. Zero chlorine calibration

• Insert the ” Zero Chlorine standard solution into the ” Container ” ( 3-2, Fig. 1) and envelope it in the ” Cover ” ( 3-1, Fig. 1 ) completely, other procedures please refer to Chapter 4-1, 4-2.

• Press the ” CAL Button ” ( 3-5, Fig. 1 ) continuously until the Display shows the text ” CAL ” and then releases the button. * During the display show text ” CAL “, press the ” CAL Button ” ( 3-5, Fig. 1 ), the display will show Now the meter is ready for the ” Zero Chlorine ” calibration
  Press ” CAL Button ” ( 3-5, Fig. 1 ) once, the Display will show the following text with flashing ( approx. 10 seconds ). Then the Display will show: Now the meter is finished the ” Zero Chlorine ” calibration procedures and is 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 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 chapters 4-1, 4-2.
     Press the ” CAL Button ” ( 3-5, Fig. 1 ) once, the Display will show the following text with flashing ( approx. 10 seconds ). Then the LCD display will return to the 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 Total standard solution

BATTERY REPLACEMENT

1. When the left corner of the LCD display shows” “, 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.
