User manual EUTECH INSTRUMENTS ECOTESTR PH 2

[. . . ] Operating Instructions EcoTestr pH 2 Waterproof Pocket Tester Conditioning Before First Use: Precipitation of the sensor electrolyte may cause white crystals to form around the cap. This is normal and does not affect the tester's performance. Fill the transparent cap of the tester with 20 mm of tap water 2. [. . . ] This tester allows up to 3-point calibration. Dip sensor in 20 mm of standard solution, stir gently and wait for the value to stabilize at or near pH 7. 00 4. Press to enter the calibration sequence. Display flashes CAL momentarily, then shows a flashing default reading 5. To confirm calibration, press and wait for the auto confirmation ( En ) 6. You have successfully completed the first calibration point 7. To obtain your second and third calibration points, proceed to the next buffer value (pH 4. 00 or pH 10. 00) and repeat step 3 - 6 8. To abort calibration, press to escape ( ESC) Maintenance: 1. Rinse sensor in tap water after each use 2. In harsh samples, take readings quickly, then rinse sensor with de-ionized water immediately to remove residues and prevent electrode contamination Useful Notes: 1. To avoid cross contamination, rinse between samples and calibration standards with de-ionized water 2. To maintain tester accuracy, use tester regularly or calibrate at regular intervals as required 3. For long-term storage, fill cap with 20 mm of storage solution (NOT de-ionized water) and replace cap*. This will keep sensor conditioned and ready for next use * The tester cap is not leak-proof. Please keep tester upright during soaking. Changing Batteries: 1. To remove batteries, lift up the front battery cover to release the front catch. [. . . ] The display shows a flashing rS (reset) 3. Press again to confirm reset ( En ) or press to escape ( ESC) reset option Warranty: This tester is supplied with a warranty against manufacturing defects for a period of ONE year from date of purchase.
