3 MethodspH-value 6.5 - 8.40.0.0Perform zero calibration (see “Operation”).Add a PHENOLRED/PHOTOMETER tablet to the 10 ml watersample straight from the foil and mix to dissolve using a cleanstirring rod. Screw the cap on and replace the vial in the samplechamber making sure that the ∇ and ∆ marks are aligned.ZeroTestpHPress the ZERO/TEST key.The method symbol flashes for approx. 3 seconds.RESULTThe pH value is shown in the display.Tolerance: bis 0.3 pH-Einheitenup to 0.3 pH units (see Notes on chemical methods).Cyanuric acid 1 - 80 mg/l0.0.0Perform zero calibration (see “Operation”).Add a CYANURIC ACID tablet to the 10 ml water sample straightfrom the foil and mix well to dissolve the tablet using a clean stirringrod. The presence of cyanuric acid will cause the solution to takeon a milky appearance.Screw the cap on and shake the vial for 1 minute. Replace thevial in the sample chamber making sure the ∇ and ∆ marks arealigned.ZeroTestCysPress the ZERO/TEST key.The method symbol flashes for approx. 3 seconds.RESULTThe result is shown in the display in mg/l cyanuric acid.Tolerance: ± 5.0 mg/l22
