Mode Selection:

Follow these steps to switch between Free and Total Chlorine testing modes.

1. With the meter off, press and hold the HOLD button and the REC/MAX/MIN button. While continuing to hold the HOLD and the REC/MAX/MIN button, press the Power button. The unit will enter the selection mode and display the current mode selected.
2. Press the TEST/CAL button to switch between Free and Total modes.
3. Press the REC/MAX/MIN button to confirm and save the mode into memory.

Note:
– For swimming pool applications, the Free Chlorine function is typically used.
– For industrial water applications, the Total Chlorine function is typically used.

Calibration Procedure:

1. The meter can be calibrated under the following calibration points:
   Free Chlorine
   – Zero ppm
   – 1.00 ppm| Total Chlorine
   – Zero ppm
   – 1.00 ppm
   ---|---

Note: The calibration procedures for the “Total Chlorine” and the “Free Chlorine” are independent of each other.

2. Calibration requires the following two solutions.
   – Zero Chlorine standard
   – 1.0 ppm standard (Free or Total)
   Calibration Procedure (continued):

3. Follow the steps below to perform calibration of the zero and 1.0ppm standards

1. Open the test chamber, place the zero chlorine standard in the chamber and close the chamber lid.
   Note: Be 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. 2) Turn on the meter. The meter will display the current mode (Free or Total) briefly then will display CAL 0.
2. Press the Zero button. The meter will show CAL 0.00, then start flashing TEST. Once complete, the meter will display 0.00 ppm. (Note: this step is not part of the calibration process, this step sets the zero point for the meter at power up)
3. Press and hold the TEST/CAL button until CAL is displayed on the display then release the button. Press the TEST/CAL button again to enter the calibration function.
4. 0.00 PPM and CAL will be displayed. With the zero chlorine standard in the chamber, press the TEST/CAL button and CAL will begin to flash on the screen. Once complete, 1.00 ppm and CAL will be displayed.
5. Replace the zero chlorine standard in the teat chamber with the 1.00 ppm chlorine standard. Then press the TEST/CAL button. CAL will begin to flash on the screen.
   Once complete, the unit will display 1.00 ppm.
6. Calibration is now complete and the meter is ready to use. (Note: It is recommended to perform the calibration at least once per day/use)

Measuring Procedure:

Note: Be sure to selected the appropriated measurement mode before performing a measurement. Refer to the Mode Selection.

1. Fill the testing bottle to the 10ML line with test sample.  

2. Open the test chamber and place the test sample in the chamber and close the chamber lid.
   Note: Be 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.

3. Turn on the meter.
   The meter will display the current mode (Free or Total) briefly then will display CAL 0.

4. Press the Zero button. The meter will show CAL 0.00, then start flashing TEST. Once complete, the meter will display 0.00 ppm.
   (Note: this step is not part of the calibration process, this step sets the zero point for the sample at power up)

5. Open the test chamber and remove the testing bottle. Open the test bottle and add the Free or Total DPD powder. Close the test bottle and shake bottle for at least 10 seconds.

6. Wait approximately one minute, then insert the test bottle back in to the test chamber and close the lid.

7. Press the TEST/CAL button, the display will flash TEST. Once complete, the display will show the measurement value.
   Note: After testing, you should wash the testing bottle with distiled water.

Measuring Procedure (Continued):
Data Hold Function

1. During the measurement, pressing the HOLD button once will hold the measured value and will display a HOLD symbol.
   Note: Press the HOLD button once again to release the data hold function.

Data Record Function
Note: The data record function only records the maximum and minimum readings.
Press the REC/MAX/MIN button once to start the data record function and a REC symbol will be shown on the display.

While REC function is active:

1. Press the REC/MAX/MIN button once to display the maximum value recorded and a MAX REC symbol will be shown on the display.
2. Press the REC/MAX/MIN button once again to display the minimum value recorded and a MIN REC symbol will be shown on the display.
   Note: If you want to delete the maximum or minimum value, press the HOLD button while viewing the value and the display will return to the REC symbol only.
   Note: To exit the REC function, press and hold the REC/MAX/MIN button until the REC symbol disappears.

Battery Replacement:

1. When the left corner of LCD display shows , it is necessary to replace the battery. However, in-spec measurements can 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 1.5 V battery ( AAA, Alkaline/heavy duty ) x 6 PCs, and reinstate the cover.
4. Make sure the battery cover is secured after changing the battery.
