The instructions listed below should be carefully followed during testing to ensure best accuracy.
• For adding the exact amount of sample and deionized
water to the cuvet it is strongly recommended to use two
class A laboratory pipettes.
• Alternatively, fill the cuvet up to the 10 mL mark: the
liquid in the cuvet forms a concavity on the top; the
bottom of this concavity must be at the same level of the
10 mL mark.
• For dosing the reagent, we recommend to use the supplied
Hanna HI 731342 automatic pipette.
For a correct use of the Hanna automatic pipette, please
follow the related Instruction Sheet.
• Color or suspended matter in large amounts may cause interference, therefore these should
be removed by treatment with active carbon and by prior filtration.
• It is important that the sample does not contain any debris. This would corrupt the reading.
• Each time the cuvet is used, the cap must be tightened to the same degree.
GENERAL TIPS FOR AN ACCURATE MEASUREMENT
Battery low: The battery must be replaced soon.
Dead battery: This indicates that the battery is dead and must
be replaced. Once this indication is displayed, the meter will
lock up. Change the battery and restart the meter.
