1.0 Using This Instruction Manual Congratulations on your purchase of a new MICRO 100 or MICRO 100 IR Laboratory Turbidimeter (MICRO 100 hereafter). This turbidimeter has been designed for simple and easy measurement of turbidity. This manual contains simple steps to follow to ensure that your instrument is operating properly. This material assumes that the user knows how to obtain representative samples of their process and has some familiarity with measuring the turbidity of samples‡ .
3.0 Becoming Familiar with the Instrument Figure 1 is a depiction of the front of the MICRO 100. Not shown in this picture are the RS-232 serial printer port and the 12V DC power plug connector, which are located on the back panel of the instrument. The user interface of the MICRO 100 has been designed with a 5 key touchpad and user display. The five keys of the Touch Pad and their functionality are described below: The key is used to turn the instrument on and off. The calibration mode.
Figure 2 illustrates all the items that can appear on the display. The upper row of the display (1) is used for reporting the turbidity levels and to provide user guidance in the customer settings routine. The lower row of the display (2) is used to display the stored turbidity reading and to communicate error messages and user guidance. The display has several status indicators (3) which distinguish the operation of the instrument.
7. If you are measuring and comparing more than one sample, pressing the enter key will display the latest reading (displayed on the lower row of the display). In addition, if you have selected printer output in the customer setup section pressing the enter key RS232 port. will output data to the 8. Repeat steps 2 through 7 for all of your samples. NOTE: The Micro 100 may display - - - for a few seconds while it determines the correct reading.
If the Micro 100 will be used over the entire range of .02 to 1000 NTU a complete calibration as described below will be required. If instrument accuracy is only required below 10 NTU, such as potable water, a calibration may be performed using only a 10 NTU and a 0.02 NTU standard. To calibrate starting at the 10 NTU, press the ubutton to bypass the 1000 NTU and proceed to Section 5.2 Calibration Procedures, step 4.
2. The turbidity value displayed in the lower row of the display should read 1000 NTU. This is the first standard that must be used in calibration. Insert the 1000 NTU calibration standard into the sample well (see figure 3) and index to the lowest value (see section 5.1 if you have not already indexed the standard) and wait for the reading to stabilize. when the standard is in 3. Press the enter key position.
6.0 User Selectable Parameters The MICRO 100 provides you the ability to customize your instrument according to your needs at any time during normal operation. This section describes how you can customize your instrument. NOTE: You cannot access any of the user selectable parameters during calibration. Enter the customer selectable parameters section of the MICRO 100 by simultaneously pressing the key while holding down the key when the instrument is operating in the normal automatic mode.
6.4 Setting the Calibration Interval After pressing the key, the upper row of the display will have the letters “Int” printed in it. This corresponds to the calibration time interval. The number in the lower row of the display corresponds to the number of days that you wish to have between scheduled calibrations (default is 30 days). Select the desired number of days between scheduled calibrations by pressing the or key to change the displayed day.
7.0 Troubleshooting 7.1 System Warning Message(s) Automatic warning messages are generated by the MICRO 100 to provide you with specific diagnostic information about the instrument. These messages are for your use and do not reduce the performance of the instrument. 7.1.1 Flashing “Cal” block A flashing "Cal" block observed during normal automatic mode indicates that you should recalibrate your instrument. The factory default is 30 days. HF recommends calibration every 30 days.
If errors 1-4 are noted, turn the instrument off and then back on. Once the instrument is back on, recalibrate the instrument. If the error persists, please contact the HF scientific Technical Service Department to rectify the error. (See Section 9.0) If error 5 is noted, replace the lamp module with a spare lamp module. If you do not have a spare lamp module, refer to Section 10.0 for ordering information. 7.3 Factory Default Parameters The MICRO 100 memory retains all original factory settings.
Lamp Replacement cont’d. 1. Remove the lamp module from the instrument by squeezing the two side tabs on the module inward while pulling the module out of the instrument. Pull the module away from the instrument until the in-line power connector is exposed (about 6-8 inches). 2. Unfasten the connector by holding on to the white in-line connector and pulling the in-line connector apart. When pulling the in-line connector apart, DO NOT hold on to the wires. 3.

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.
WARRANTY HF scientific, as vendor, warrants to the original purchaser of the instruments to be free of defects in material and workmanship, in normal use and service, for a period of one year from date of delivery to the original purchaser. HF scientific’s obligation under this warranty is limited to replacing, at its factory, the instrument or any part thereof.
