Page 3: Overview
The instrument uses infrared light emitting diode (LED 860±30nm) as the light source and 90° scattering method, which is compliant with ISO7027 and DIN EN 27027 standards for the determination of the turbidity for water solutions. TN480 allows you to measure turbidity in a reliable and simple manner wherever you are. -

Keypad Functions ⚫ Power on/off ⚫ In measurement mode, press to enter or exit calibration mode ⚫ In calibration mode, press to exit calibration mode ⚫ In parameter setup and data recall mode, press to return to measurement mode ⚫ In measurement mode, short press to perform single measurement; long press (>3s) to perform continuous measurement. - Page 9 measurement mode, one serial number corresponds to multiple measurements (according to user’s setting) in the measurement interface. The data, as shown in Diagram 5, has 10 measurements. Obviously, for one measurement interface, the memory storage of the normal measurement is different to that of TruRead measurement.

Page 10: Calibration
CALIBRATION Preparation for Calibration Calibration point The instrument has 5 calibration points: 0 NTU, 20 NTU, 100 NTU, 400 NTU, and 800 NTU. Among them, 0 NTU point uses AMCO 0.0 NTU calibration solution or laboratory distilled water, and the remaining 4 calibration points use AMCO polymer solutions. Note that the cap of the 0.0 NTU solution cuvette can be unscrewed. -
Page 11: Calibration Procedure (Take 0 Ntu And 20 Ntu As An Example)
Be careful not to shake the solution vigorously, as this will create air bubbles which will destabilize the measurement; For 0.0 NTU calibration solution, do NOT shake or flip. If using Formazin calibration solution, as it tends to precipitate easily, each time users must flip and shake the cuvette to make the solution even. -

6) If you want to continue to calibrate 100, 400 and 800 NTU, place the 100 NTU calibration cuvette in the sample cuvette holder and press to calibrate. After calibration is done, press to confirm; repeat the steps to calibrate 400 NTU and 800 NTU. After calibration is done, press to return to measurement mode. -

impact on the measurement accuracy of low turbidity solutions. When the reading is displayed as 0.00 NTU, if a positive error occurs, a 0.0 NTU calibration solution can be used for verification test. If a negative error occurs, it cannot be verified. For this instrument, there is a Zero Turbidity Error Reminder function. -

c) Make sure the surface of the cuvette is dry, clean and free of stains. Apply a small drop of silicone oil on the surface of the cuvette and wipe it off with a micro-fiber cloth. Then wipe again with filter paper or high-quality tissue paper. -
Page 15: Notes For Measurement
5.4 Notes for Measurement Keep the sample stable: After the cuvette is placed into the sample cell, it is recommended to wait for 1 to 2 minutes before calibration, as the solution will experience some shaking when the cuvette moves, which may result in inaccurate measurements. Sample Cuvette cleaning requirement: Sample cuvette must be rigorously cleaned and free from smudges and scratches. -
