Digital PH Tester Meter Temperature Acidity Acid Aquarium Pool Water ct-6020a OPERATING INSTRUCTION Please pull out the cap of the pH probe at the bottom of the pH meter, and connect the meter with the external probe, lock it in the clockwise way. Be careful with the storage solution (KCL) when take the cap off from the probe. * Hold Feature A flashing dot will be displayed during the measuring mode, Press HOLD to freeze the current reading. Press HOLD again to release the hold mode. * Automatic Temperature Compensation (ATC) The product is capable of measuring the temperature and making compensation automatically, ?ATC? shows at the left corner of the screen. * Calibration 1. Prepare 4.01 and 7.00 or 10.01 pH buffers, Use 7.00 pH buffer for the mid-range buffer first. The pH values for the buffers are given for 25 ?C. If the sample temperature is not 25 ?C, the pH values displayed for the buffers will reflect the correct pH value for the sample temperature. If the electrode is dry, submerge it in distilled water for 10minutes before calibration. Ensure that the calibrating buffers are fresh. 2. Press ON/OFF key to turn the meter on, submerge the probe in the buffer while stir gently. Then keep it still until a stable reading is reached. Press CAL for 3 seconds until the Text ?CAL? appears. Then release CAL, the meter will identify the current buffer value automatically, and display 7.00 in the LCD. The result will be saved while the text ?SA? displayed after 2 seconds. The meter will back to measuring mode after 1 second while text ?End? showed. 3. If text ?End? is showed after press CAL, it means the calibration buffer is not fresh or the probe is aging. 4. Do not take out the probe from the buffer until text ?End? is showed in the LCD. 5. Same steps as calibrating pH 4.01 and 10.01. * If Out of the Range l If the pH value is lower than 0 or higher than 14, ?-- -- --? will be displayed. l When the temperature is too low or too high, ?L? or ?H? will be displayed. * Low Power Indication Change batteries if LCD is flashing.

- MAINTENANCE Please always keep the ph glass bulb caped for protecting when storing. Always rinse the ph electrode in distilled water before use. Never touch or rub glass bulb for it may reduce the life of the electrode. WARRANTY The meter is warranted to be free from defects in material and workmanship for one year from the date of purchase. This warranty covers normal operation and does not cover battery, misuse, abuse, alteration, tampering, neglect, improper maintenance or damage resulting from leaking batteries. Proof of purchase is required for warranty repairs. Warranty is void if the meter has been taken apart. Note: How to prepare the buffer solution Solid material for ph4.01, ph7.00, ph10.01 buffer solution are provided in a set of sachets. Glass jars or beakers are recommended as the solution containers. Take making the 250ml buffer solution of pH 7.00 as an example: (1) Put the pH 7.00 buffer material (in the green sachet) in a jar (the volume should be no less than 250ml). (2) Fill the jar with 250ml distill water. (3) Place a glass stick in the solution, swirling it until the white powder dissolved. (4) Store the buffer solution in the cool and dry place. Attach a label on it for further use. (5) For the further calibration, Ensure that there is a constant supply of fresh buffer solution in contact with the probe. Discard the solution after use.
