    A menu is a list of choices. This allows a selection of various tasks for the TC-3000 to perform, such as, scan blank and scan sample. The keypad is used to make menu selections that are viewed on the display.

  • Page 14: The Display & Menus

    Think of the menu selections as a vertical list in the display that moves up or down each time an arrow button (‡ or ˆ) is pressed. All menus in the TC-3000 are looping menus. The top and bottom menu choices are connected in a loop. Scrolling down past the bottom of the menu will lead to the top of the menu.

  • Page 18: Tubes

    Tubes The TC-3000 uses one type of tube (Code 0290) for the turbidity, color and chlorine tests. There is no need for a special turbidity tube. The handling of the tubes is of utmost importance. Tubes must be clean and free from lint, fingerprints, dried spills and significant scratches, especially the central zone between the bottom and the sample line.

    0.1 NTU. The trend has been to check the calibration of on-line turbidimeters with hand-held field units. The optical design and low detection limit of the TC-3000 allow very accurate readings for such calibrations. The meter also allows the user to choose the units of measure for expressing turbidity.

    (FNU). The TC-3000e meets the EPA specification and the TC-3000i meets the ISO specification. The nephelometric method is most useful for low turbidity. The TC-3000 is a nephelometer that is capable of measuring turbidity by both the attenuation method and the nephelometric method. It uses a detector placed at 180°...

  • Page 22: How Is Chlorine Measured

    TC-3000 makes it ideal for such measurements. Because of its wide range, the TC-3000 can be used to measure the water used in the wastewater process, in a distribution system and for many low level discharge requirements.

  • Page 23: How Is Color Measured

    The color determination in the TC-3000 uses a 375 nm wavelength. This UV light was found to give the greatest sensitivity in reading the APHA color standards. The results are expressed as APHA color units (cu).

  • Page 41: Dilution Procedures

    Dilution Procedures If a sample is encountered that is more than 4000 NTU, a careful dilution with 0 NTU or very low turbidity water will bring the sample into an acceptable range. However, there is no guarantee that halving the concentration will exactly halve the NTU value. Particulates often react in an unpredictable manner when diluted.
