Read the operating instructions carefully and especially observe the safety information. If you do not follow the safety instructions and information on proper handling in this manual, we assume no liability for any resulting personal injury or damage to property. Such cases will invalidate the warranty/ guarantee. a) General Information

• The device is not a toy. Keep it out of the reach of children and pets.

• Do not leave packaging material lying around carelessly. This may become dangerous playing material for children.

• Protect the appliance from extreme temperatures, direct sunlight, strong jolts, high humidity, moisture, steam and solvents.

• Do not place the product under any mechanical stress.

• If it is no longer possible to operate the product safely, take it out of operation and protect it from any accidental use. Safe operation can no longer be guaranteed if the product: - is visibly damaged, - is no longer working properly, - has been stored for extended periods in poor ambient conditions or - has been subjected to any serious transport-related stresses.

• Please handle the product carefully. Jolts, impacts or a fall even from a low height can damage the product.

• Consult an expert when in doubt about the operation, safety or connection of the appliance.

• Maintenance, modications and repairs must only be completed by a technician or an authorised repair centre.

• If you have questions which remain unanswered by these operating instructions, contact our technical support service or other technical personnel.

• For schools and educational institutions, the use of this product must be supervised by trained staff. 19b) Batteries

• Correct polarity must be observed while inserting the battery.

• The batteries should be removed from the device if it is not used for a long period of time to avoid damage through leaking. Leaking or damaged batteries might cause acid burns when in contact with skin, therefore use suitable protective gloves to handle corrupted batteries.

• Batteries must be kept out of reach of children. Do not leave batteries lying around, as there is risk, that children or pets swallow them.

• All batteries should be replaced at the same time. Mixing old and new batteries in the device can lead to battery leakage and device damage.

• Batteries must not be dismantled, short-circuited or thrown into re. Never recharge nonrechargeable batteries. There is a risk of explosion! c) Cell Chamber

• The cell chamber (4) must be kept dry. Do not insert wet cells (7) for testing! Water can destroy the electronic components. d) DPD Method Performance

• The accuracy of the measurements depend on factors relating to the overall method which include the meter, the glass cells, reagents and testing procedure. e) Sample Cells

• These are made from glass and can get damaged if dropped. Handle with care.

• Discard cells (7) that are badly scratched, this can affect the accuracy of results. Use the included cell covers (5) and caps (6) for protection during transport and storage. 20f) Reagent Strips

• Test reagents must be used within the best before date.

• Do not leave DPD-1 and DPD-4 reagent strips and samples unattended. They could be swallowed by children and pets.

• The reagent strip pads are not hazardous but may cause irritation.

• Avoid the following types of contact: Contact First Aid Eyes Flush with copious amounts of water for at least 15 minutes. Contact a physician. Skin Rinse with copious amounts of water. Contact a physician. Ingestion Consume 1-2 glasses of water. Call a physician or poison control.

Toggle between FCL (B) and TCL (C) mode. Zero calibration. In RECALL mode (G), browse records. Store the current reading. Press and hold for 3 seconds to enter RECALL mode (G).

8. Replacing Batteries

Stored readings will not be lost when batteries are replaced or run out. Replace batteries if the low battery symbol shows.

• Remove the battery compartment (1) screws using a plus-head screwdriver

• Insert the batteries matching polarities as shown inside the compartment.

• Replace the compartment cover and fasten the screws. To preserve battery life, meter will automatically shut down after 10 minutes of no activity. Press to turn the meter back on.

239. Testing Procedure

Samples should be analyzed as soon as possible after collection. Exposure to sunlight, other strong light, or agitation will accelerate the reduction of chlorine.

• Use the measuring cup to ll the cell with 10 ml of sample liquid then screw the cap on. Use a lint free soft cloth to dry the cell (7) and wipe any ngerprints off before inserting into the cell chamber (4).

• Press to turn the meter on.

• Press and hold for two seconds to select FCL (B) or TCL (C) mode.

• Put the cell (7) into the chamber (4), and line the dot on the cap (6) with the triangle on the meter.

• Press and hold for two seconds to adjust to zero.

• After the reading (D) stops ashing and shows “0.00”, remove the cell (7).

• Unscrew the cap (6) and insert one FCL (DPD-1) strip or one TCL (DPD-4) strip into the sample solution.

• Fan the strips in a gentle back and forth motion (approximately 2 strokes per second) for 20 seconds, then remove the strip.

• Screw the cap (6) back on and wipe the cell (7) dry, taking care not to leave any ngerprints on the glass. Bubbles can lead to incorrect measurements. If needed gently swirl the cell (7) to remove any bubbles before testing. Do not agitate the sample.

• Insert the cell (7) into the chamber (4), lining the marks up as shown above.

• Press to get a reading. Thoroughly rinse cells (7) and caps (6) with distilled water after testing. If reagent is left inside for too long they may stain the glass which will affect accuracy. 2410. Store and Recall Readings

• After getting a reading, press to store the current reading. The STORE (F) icon and the ordinal of this record will appear on the display (H).

• Press and hold for 3 seconds to enter RECALL mode (G). In this mode, press or to browse records.

• Press and hold to exit this mode and return to measuring mode.

• In RECALL mode (G), press and together for 3 seconds to clear all stored readings.

11. Care and Cleaning

Be careful not to scratch the glass cells (7) as this can affect the accuracy of readings. Do not get the meter wet. Any liquid entering the cell chamber (4) can damage the electronics

• Do not use any aggressive cleaning agents, rubbing alcohol or other chemical solutions as they can cause damage to the meter housing and malfunctioning.

• The meter is generally maintenance free.

• Use distilled water to rinse the glass cells (7) and caps (6) before and after each use.

• Clean the product with a dry, bre-free cloth. 2512. Disposal a) Product Electronic devices are recyclable waste and must not be disposed of in the household waste.
