FOREWORD HF TURBIDIMETERS HF turbidimeters are manufactured to meet design criteria for nephelometers as described in Standard Methods For Examination of Water and Wastewater. HF turbidimeters are approved by the U.S. EPA* as a means to measure the turbidity of potable water, waste water, and other liquids. HF turbidimeters provide a linear display of turbidity, throughout all ranges, in Nephelometric Turbidity Units (NTU).

F. COMPLIANCE TESTING CERTIFICATION The Micro 200 BW has undergone extensive testing, therefore, HF scientific, inc certifies that this instrument has met the following standards. Product Safety US standard tested by ETL testing labs to UL 3111 Canadian Standard tested by ETL to CSA 1010.
II. INSTALLATION A. PACKING LIST FOR THE MICRO 200 BW CONTENTS QUANTITY must be mounted where it can be viewed at the backwash control station. In this example, for convenience of maintenance, the turbidity sensor should be mounted at the backwash station and have the water plumbed to it. The analyzer must be mounted in a location that avoids direct water contact. Refer to figure 2 on page 7 for outline dimensions.

instrument. The desiccant pouch is designed to have a long life; however, replacement of the desiccant pack will be required from time to time. To determine the condition of the desiccant, check the included humidity indicator card. If required, a new foil sealed desiccant pouch and indicator card are available from HF scientific inc. part #21555R. It is essential that all enclosure seals be maintained.
the voltage. The correct fuse ratings are 5 x 20 mm 1A fast acting for 120 VAC and 5 x 20 mm ½A fast acting for 240 VAC. A power switch is located to the right of the power cord. WARNING: If power connection is to be hardwired, place each analyzer on a separate circuit breaker or switch to allow for service. Observe all local wiring codes. BW analyzer). 5. Recorder - Current A 4-20 mA current output is available. The connections are made at the terminal block labeled Analog 4-20 mA (J5).
WARNING: While the chance is slight, there are fault conditions under which a hazardous voltage could be exposed on the analog output wires when the jumper J13 is removed. To preclude this possibility HF scientific strongly recommends, for personal protection, that a Ground Fault Circuit Interrupter (GFCI), such as LEVITON part number 6599 or 5299, be used at the power connection.

B . START UP Before placing the MICRO 200 BW on line we recommend that you standardize the instrument. The following sections describe the required procedures. 2. Standardizing The reference standard (cuvette) supplied with the MICRO 200 BW is a pure liquid sealed in glass. It has a value of 0.02 NTU. 1. Indexing The United States Environmental Protection Agency (U.S. EPA) recommends that cuvettes used for instrument calibration or sample measurement be indexed.
The desiccant beads are dark blue when dry and turn to a light pink when expended. Check the desiccant on a quarterly basis or if after cleaning the cuvette readings appear erroneously high to ensure proper operation of the vaporpurge feature. It is important to keep a cover on the sample well if the flow through head is out for more than a few minutes, to avoid saturating the desiccant uselessly.
Figure 11 Vaporpurge MICRO 200 BW 0 - 1000 NTU (5/05) Rev. 3.
is accomplished by washing the interior and exterior of the cuvette in a detergent solution, then rinsing thoroughly 8 to 10 rinses in clean, distilled water, to remove all streaks.

Secondary Standard Set (optional) Catalog No.
b. Standard Formazin Solutions Calibration of this instrument is based on Formazin, a material which is made by polymerization. Calibration samples may be obtained by diluting Formazin stock suspension using “Turbidity-Free” water. Formazin stock suspension can be prepared by the user (Reference Standard Methods For Examination of Water and Wastewater) or a kit can be purchased from, HF scientific, inc., Catalog No. 50040.
VI. SECURITY ACCESS CODE The security access code for the MICRO 200 BW provides a degree of protection against an unauthorized change to the instrument’s settings or parameters. The security code feature may be turned off if desired. The first requirement for the security access code after “power-up” is when you wish to exit the current display screen (turbidity or backwash). Upon pushing the MENU button to leave the display screen, a request will be made for the security access code.
VII. TROUBLESHOOTING A. GENERAL NOTES Service and technical support are available from the manufacturer, HF scientific inc. from 8:00 AM to 4:00 PM Eastern Standard Time. The following Table will supply fundamental troubleshooting information. The Guide assumes that the controls and functions of the instrument are used correctly. The intention of the guide is to eliminate common faults, not to troubleshoot down to component level. GUIDE TO FUNDAMENTAL TROUBLESHOOTING SYMPTOM SOLUTION Display not lit.

VIII. OPTIONS chosen that best averages the backwash water over the cycle. The sensor should also be located as close to the backwash filter as possible to reduce the time delay of the water sample. This will give the operator a correct picture as to how the backwash is proceeding and when it is complete. Refer to figure 20 for sensor outline dimensions. BACKWASH A. INSTALLATION 1.
about three inches. Care must be used to not nick the wires under the jacket. Note that the sensor cable is composed of two pairs of wires. Each pair consists of two insulated wires and an uninsulated shield wire, wrapped individually in a foil shield. The wire pairs are RED & BLACK and WHITE & BLACK. The foil can be unwrapped and removed, while keeping the pairs together. The two shield wires should be wrapped together. The remaining wires need to have the insulation stripped back about ¼”.
c. Analog Outputs Analog outputs of either 4-20 mA or voltage are available. If you select voltage you may choose 0-10V, 0-1V or 0-100mV. This analog output will be shared by both modes and will automatically recalibrate to the selected mode. d. Serial Port (Optional) If a serial port is connected the readings will report in NTU while in the turbidity mode and will report in %T while in the backwash mode.
between the most remote MICRO 200 BW analyzer and the host computer does not exceed 50 feet (16.4 m.). Due to it’s “tri-state transmitter” design, the companion MICRO 200 BW units, which are on the same serial port at the host computer, may be “hubbed” or connected each one to the next as long as the total cable length from each MICRO 200 BW to the host computer does no exceed 50 feet (16.4 m.).
