  • Page 8: Overview

    The Micro 1000 process turbidimeter allows you to measure the turbidity of your process water. The White Light Micro 1000 has been designed to meet the design criteria specified by the US EPA on turbidity measurement. The Infra-Red Micro 1000 (Micro 1000 IR) was designed to meet the design criteria specified in ISO 7027 and DIN 27027 for the measurement of the turbidity of a sample.

  • Page 9: User Interface

    2.2.User Interface The user interface of the instrument is designed with a 6 key touch pad and a single user display. The six keys of the touch pad and their functionality are described below. Figures 1a and 1b are depictions of the front and rear views of the instrument. Optical Well Display Lamp Module...

    The ON/OFF key ( ) key is used to turn the instrument ON or OFF. The enter key ( ) is used to accept information. The up and down arrow keys ( ) are used to set and reset numerical values and to change instrument modes. The left and right arrow keys ( and ) are used to scroll through lists.

  • Page 11: Routine Operation

    Routine Operation 4.1. Measurement Principle & Methodology This instrument is designed to measure the turbidity of a sample in nephelometric turbidity units (NTU). In addition, the instrument is capable of measuring in several other standardized scales: Applicable Instrument (s) Scale Definition White Light Infrared...

  • Page 12: Grab Sample Measurement (Routine Measurement)

    WARNING: NEVER pour liquid directly into the sample well of the instrument: always use a cuvette. The instrument will accurately measure the turbidity of a sample using only cuvettes with the black light shield on the cuvette (provided by HF scientific, inc.), the optional pour through assembly, or the optional flow through assembly.

  • Page 13: Pour Through Sample Measurement (Optional Accessory)

    5. Completely fill the rinsed cuvette (from step 4) with the remaining portion (approximately 30 ml) of the grab sample and then cap the cuvette with the black light shield. Ensure that the outside of the cuvette is dry, clean and free from smudges. 6.

  • Page 14: Dry Air Purge System

    4.5. Dry Air Purge System Cold samples, or the continuous flow of cool water through the flow-through cuvette may cause condensation on the walls of the cuvette. This condensation can cause faulty and erratic readings with the instrument. To eliminate this effect, a built in dry air purge system has been designed to optimally circulate air through the optical compartment and prevent this condensation.

  • Page 15: Calibration Standards

    Note: The instrument must be re-calibrated after lamp replacement. 5.1. Calibration Standards HF scientific, inc. recommends that you use the following materials during calibration to achieve the accuracy stated in this manual: 1. 0.02 NTU Calibration Standard available from HF scientific inc.

  • Page 16: Calibrating The Instrument

    When using the standards in the future, always insert the standard so that the pointer of the index ring faces forward. Slowly rotate the standard back and forth about 5° to find the lowest point. The standard is now indexed and ready to use. 5.3.
  • Page 17 Press the key to indicate to the instrument that you plan to calibrate on this point. 4. Insert the 1750 NTU calibration standard into the sample well and calibrate as before. When the instrument has completed the calibration, the “Cal” and the “Store” blocks will quit flashing and the lower row of the display should now indicate that the 10000 NTU standard is the next standard to be used for calibration (10.0 K).
  • Page 18 7. Insert the 10.0 NTU calibration standard into the sample well and calibrate as before. When the instrument has completed the calibration, , the “Cal” and the “Store” blocks will quit flashing and the lower row of the display should now indicate that the 0.02 NTU standard is the next standard to be used for calibration.

  • Page 19: Instrument Configuration (Setup) Mode

    associated warning or error message(s) will be displayed in the lower row of the LCD screen. Refer to the section on troubleshooting to determine the cause of the warning or error. 3. At any point in time during calibration, you can cycle through the required calibration points (0.02 NTU, 10 NTU, 100,0 NTU, 1750.0 NTU, and 10000.0 NTU) by pressing either the key to individually calibrate with a particular calibration standard.

  • Page 20: Selecting Display Resolution

    This feature is designed to decrease the sensitivity of the instrument to dissolved materials that may adversely affect a turbidity reading (e.g. dissolve material creating color). Press either the keys to change the operational state of this option in the instrument. When you have selected the desired state press the 6.3.
  • Page 21 The upper row of the display will indicate the operational status of the security access option (on or off). You can change the operational status of this option using either the keys. Once you have set the desired status, press the key to accept it.

  • Page 22: Setting Up The Rs232 Port (Printing Function)

    6.5. Setting up the RS232 Port (Printing Function) After pressing the key, the Print block will be lit and the lower row of the display will indicate the state of the RS232 port. This feature allows you to select the function of the serial port on the instrument. There are two options to choose from: Off and Timed Output.

  • Page 23: Setting The Calibration Interval

    6.6. Setting the Calibration Interval After pressing the key, the lower row of the display will have the letters “Int” printed in it. The number in the upper row of the display corresponds to the number of days that you wish to have between scheduled calibrations (default is 30 days).

  • Page 24: Setting The Time (Hours And Minutes)

    Day:Month block will remain displayed and the second number on the upper row of the display will be flashing: this number corresponds to the day of the month. Select the correct day by pressing either the keys to change the displayed day. When you have selected the proper day, press the key.

  • Page 25: Exiting The Setup Mode

    6.9. Exiting the setup mode After you have pressed the key for selecting the time, the word “END” will be shown on the lower row of the display. You may also reach this point by pressing either the key until the word “END” appears on the lower row of the display.

  • Page 26: Troubleshooting

    A flashing "Cal" block observed during normal automatic mode indicates that you should re- calibrate your instrument. The factory default is 30 days. HF scientific inc. recommends calibration every 30 days. The flashing "Cal” block is only a warning and does not mean that the instrument will stop performing accurately.
  • Page 27 7.1.3. Other warning messages (W-XX) The following table outlines the general warning messages that could arise (normally after calibration is performed). Rev. 2.3...
  • Page 28 WARNING ASSOCIATED MEANING TYPICAL CAUSE W-01 Lamp Failure The lamp is no longer working, or the light output of the lamp is too low for normal operation. W-02 Transmission detector #1 error Transmission detector #1 failed to report the proper signal levels during calibration (the detector circuitry has failed or calibration was performed with the wrong standards).

  • Page 29: System Error Message(S)

    When these messages are observed and if you do not understand the instructions shown below, contact the HF scientific, inc. Technical Services department to determine a resolution to the problem. The instrument indicates an error message when an "E-XX" is displayed on the lower row of the display.

  • Page 32: Glossary

    Glossary Formazin Turbidity Units (FTU): see Nephelometric Turbidity Units Indexing a Cuvette: The United States Environmental Protection Agency (US EPA) recommends that cuvettes used for turbidimeter calibration or sample measurement be indexed. To index a cuvette with a sample in it, slowly rotate the cuvette throughout one complete revolution (360°). While rotating the sample cuvette, observe the display and locate the position that the cuvette is in which provides the lowest turbidity reading.
