Page 8: General Description
1.1 General description The AL400T-WL is designed to meet the criteria specified in U.S. EPA 180.1 on turbidity mea- surement. The AL400T-WL allows for the measurement of turbidity in the field. The instrument features auto ranging over the range of 0.01 to 1100 NTU/FNU. -
Page 9: Important Notes
1.4 Important Notes 1.4.1 Guidelines for turbidity measurements Vials and caps should be cleaned thoroughly after each test to avoid interferences. Minor residuals can cause errors. The outside of the vial must be clean and dry, before starting the test. Wipe the vials with a smooth cloth to remove fingerprints or waterdrops. -

2.2 Overview of function keys The key pad has five buttons: Switching the photometer on or off. Perform a calibration. Perform a measurement. When pressed and held this key can be used to index the current sample. When the key is released a reading or calibration starts. -
Page 15: Operation Mode
2.3 Operation mode This instrument measures turbidity. The turbidity is reported in Nephelometric Turbidity Units (NTU) and Formazin Nephelometric Units (FNU). Readings above 1100 NTU are outside the range of this instrument. Note: Nephelometric turbidity units (NTU’s) are numerically equivalent to Formazin ne- phelometric units (FNU’s). -
Page 16: Perform Turbidity Measurement
2.3.1 Perform turbidity measurement Accurate turbidity measurements depend on good, consistent measurement techniques. This includes working with clean sample vials in good condition and removing air bubbles. Samples should be measured immediately to prevent changes in sample characteristics due to temperature shifts and settling. Instrument operation: Take a representative sample in a clean container. - Page 17 Place the vial in the sample chamber making sure that the positioning is correct, with the marks are aligned. Index the cuvette by pressing and holding down the [ ] key while rotating the cuvette to identify the lowest reading (the displayed turbidity is continuously updated on the display).

Page 18: User Calibration
2.3.2 User calibration 2.3.2.1 When to calibrate? The turbidimeter was calibrated at the factory and does not require user calibration before use. Therefore, it is possible to use the instrument directly out of the box. However, re-calibration of the instrument is recommended to help with familiarization and the operation of the in- strument and the calibration procedures. - Page 19 5. Insert the 10.0 NTU standard into the sample chamber and press down until the cuvette snaps fully into the instrument. Align the indexing ring with the arrow on the instrument (see section 2.3.3.4 if the standard is not already indexed). 6.

2.3.2.3 Calibration Error If the screen shown below is displayed after calibration, the ER R internal diagnostics have determined that the calibration standards were bad or that they were inserted in the wrong order. Either check the standards and recalibrate or restore the factory calibration as mentioned below. -

Page 22: Measurement Of High Turbidity Values
2.3.3.2 Measurement of high turbidity values High turbidity samples with more than 1100 NTU ("overrange") may be diluted. The dilution water should be a water with very low turbidity. For accurate dilution proceed as follows: Mix the water sample well and pipette x ml of the water sample (see table below) into a 100 ml volumetric flask. -
