reporting the turbidity levels and to provide user guidance in the customer setting 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. In addition, the
"LoBat" block (4) flashes when the batteries need to be replaced. Finally, several indicators (5) provide guidance
when the customer setting routine is being used and when the calibration routine is being used.
4 Routine Operation
The CyberScan TB1000 measures and reports the turbidity of a sample in nephelometric turbidity units (NTU).
NOTE: Nephelometric turbidity units (NTU’s) are numerically equivalent to Formazin turbidity units (FTU’s) (See
Glossary).
Sections 4.1 and 4.2 describe how to use the CyberScan TB1000 under normal operating conditions. These
sections include details on how to input certain customer selectable parameters and how to take normal, routine
turbidity measurements using the CyberScan TB1000.
4.1 Grab Sample Measurement (Routine Measurement)
The following steps describe how to measure the turbidity of a sample using the CyberScan TB1000:
1. Turn on the CyberScan TB1000 using ON key. The instrument will be in the normal mode (the "AUTO"
block should be illuminated). Allow instrument to warm up for at least 30 minutes.
2. Sample approximately 100 ml of the process stream as you would normally do for turbidity measurement.
3. Obtain a clean and dry sample cuvette.
4. Rinse the cuvette with approximately 20 ml of the sample water (2/3 of cuvette volume), capping the
cuvette with the black light shield (cuvette top) and inverting several times. Discard the 20ml of used
sample and repeat the rinsing procedure two more times.
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. Place the cuvette in the CyberScan TB1000 and index the cuvette to the lowest reading (the displayed
turbidity is continuously updated on the upper row of the display). Once the cuvette is indexed, the
reading displayed on the CyberScan TB1000 display should be recorded as the sample turbidity (see
Glossary for more information on indexing a cuvette).
** Any typical glass cleaner can be used along with a lint free cloth, or tissue, to clean the outside of the
cuvette.
7. If you are measuring and comparing more than one sample, pressing 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 ENTER key will output data to the RS232 port. Repeat steps 2 through 7
for all of your samples.
NOTE: The CyberScan TB1000 may display “- - -“ for a few seconds while it determines the correct reading.
NOTE: An indication of “Or” (over-range) in the upper row of the display indicates that the standard in the sample
well is higher than 1000 NTU.
WARNING: NEVER pour liquid directly into the sample well of the CyberScan TB1000, always use a cuvette.
The CyberScan TB1000 will accurately measure the turbidity of a sample using only cuvettes with the
black light shield on the cuvettes provided or the optional pour through assembly.

4.2 Pour Through Sample Measurement (Optional Accessory)
Install the pour through assembly and index it according to the instruction sheet that accompanies the assembly.
The following steps describe how to measure the turbidity of a sample using the CyberScan TB1000 fitted with
the optional pour through assembly:
1. Turn on the CyberScan TB1000. The instrument will be in the normal automatic mode (the "AUTO" block
should be illuminated). Allow instrument to warm up for at least 30 minutes.
2. Sample approximately 500 ml of the process stream as you would normally do for turbidity measurement.
3. Pour the complete 500 ml sample into the pour through assembly. Record the turbidity of the sample
displayed after the entire 500 ml sample has been poured into the assembly and the flow to drain has
ceased, and after the reading has stabilized.
4. If you are measuring and comparing more than one sample, pressing ENTER key will store the reading
(displayed on the lower row of the display). In addition, if you have selected printer output in the customer
setup section pressing ENTER key will output data to RS232 port.
5. Repeat steps 2 through 4 for all of your samples.
The sample cuvette used in the pour through assembly is identical to the two standard sample cuvettes supplied
with the CyberScan TB1000. Clean the cuvette on a periodic basis according to your experience with the type
and turbidity of the sample found in your facility.
5 Calibration Procedures
The CyberScan TB1000 Turbidimeter has been factory-calibrated using Eutech Instruments calibration standards
that are traceable to the primary turbidity calibration standard, Formazin. It is possible to use the instrument
directly out of the box. However, re-calibration of the instrument using the calibration set included is
recommended to allow you to become familiar with the operation of the instrument and the calibration procedures.
Eutech Instruments recommends that you use the following materials during calibration to
achieve the accuracy stated in this manual:
1. De-ionized water filtered through a 0.2 µm filter, or 0.02 NTU Calibration Standard
2. 10.0 NTU Calibration Standard
3. 1000 NTU Calibration Standard
Under normal conditions, re-calibration is recommended at least once every three months. You can
select a predetermined calibration interval (see section 5.3) for automatic prompting for calibration: if
you exceed the selected calibration interval, the "Cal" block will flash until the instrument is re-
calibrated.
NOTE: It is well known that diluted Formazin is unstable. If you choose to use Formazin to calibrate the
CyberScan TB1000, ensure that you are using a fresh stock suspension of Formazin to achieve the accuracy
quoted for the CyberScan TB1000. The Eutech Instruments calibration standards are more stable than Formazin
and have a shelf life of 1 year. If you use the stable Eutech Instruments calibration standards to calibrate the
instrument, review the expiration date to ensure that the standards have not expired.
NOTE: The CyberScan TB1000 must be re-calibrated after lamp replacement.
5.1 Indexing the Calibration Standard(s)
The United States Environmental Protection Agency (US EPA) recommends that cuvettes used for instrument
calibration or sample measurement be indexed. To comply with this recommendation, each Eutech Instruments
calibration standard is supplied with an indexing ring and each CyberScan TB1000 is supplied with an indexing
pin for quick and repeatable indexing of the calibration standard. The white indexing pin is installed on the collar
ring around the optical well.

CyberScan TB1000

To index a calibration standard perform the following steps:
1. Slowly rotate the calibration standard one complete revolution (360°).
2. While rotating the standard, observe the CyberScan TB1000 and locate the cuvette position with the
lowest turbidity reading.
3. With the calibration standard positioned at the location having the lowest turbidity reading, install the
Indexing Ring over the black light shield on the standard so that the pointer of the Ring aligns with the
Indexing Pin.
5.2 Calibration Procedure
Even though it is possible to calibrate the CyberScan
TB1000 using any sequence of the prescribed calibration
standards, to achieve the stated accuracy you must use
the procedure below to calibrate instrument.
1. Press CAL key. Once this key is pushed the
“Ident” block and the “Cal” block will illuminate on
the display.
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) by aligning the notch
and the indexing pin (see section 5.1 if you have
not already indexed the standard) and wait for the
reading to stabilize.
3. Press ENTER key when the standard is in
position. After the enter key has been pressed,
the instrument will calibrate on the 1000 NTU level
(the “Store” block will flash) and the upper row of
the display should display 1000 NTU. The lower
row of the display now shows that the 10.0 NTU
calibration standard should be placed in the sample well for continuing calibration sequence.
4. Insert the indexed 10.0 NTU calibration standard into the sample well by aligning the notch and the
indexing pin (see section 5.1 if you have not already indexed the standard) and wait for the reading to
stabilize.
5. Press ENTER key when the standard is in position. After the enter key has been pressed, the instrument
will calibrate on the 10.0 NTU level (the “Store” block will flash) and the upper row of the display should
display 10.0 NTU. The lower row of the display now shows that the 0.02 NTU calibration standard should
be placed in the sample well for continuing the calibration sequence and wait for the reading to stabilize.
6. Insert the indexed 0.02 NTU calibration standard into the sample well by aligning the notch and the
indexing pin (see section 5.1 if you have not already indexed the standard).
7. Press ENTER key when the standard is in position. After the ENTER key has been pressed, the
instrument will calibrate on the 0.02 NTU level. The instrument automatically exits out of the calibration
mode and then returns to the normal automatic mode. The display should read 0.02 NTU since this is the
turbidity level of the standard that is still in the sample well. At this point, you have calibrated the
instrument so that it measures accurately across the full range of the instrument.
8. Proceed to use the instrument normally.
NOTE: During calibration, the CyberScan TB1000 will perform some system self-diagnostics. Several error
messages may be displayed. If there is an error, one of the four error messages E01, E02, E03, and E04 will be
displayed in the lower row of the display (see section 7.2).
NOTE: At any point in time during calibration, you can cycle through the required calibration points (0.02 NTU,
10 NTU, and 1000 NTU) by pressing either ▲or ▼keys to individually calibrate with a particular calibration
standard. If you wish to exit the calibration mode you may do so at any time by simply pressing the CAL key.
However, exiting the calibration process without completing the steps for calibration may cause the accuracy of
the instrument to be diminished.

7 Troubleshooting
7.1 System Warning Message(s)
Automatic warning messages are generated by the CyberScan TB1000 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. Eutech Instruments recommends calibration every 30 days. The
flashing "Cal" block is only a warning and does not mean that the instrument will stop performing accurately. The
"Cal" block will flash until you have recalibrated the instrument.
7.1.2 Flashing “LoBat” block
A flashing “LoBat” block on the display indicates that the backup batteries need to be replaced. Under this
condition, the parameters that are stored in memory (all of the user settable parameters and the instrument
calibration) may be lost under conditions when power is not supplied to the instrument. See section 8.3 for
instructions on replacing the batteries.
7.2 System Error Message(s)
Error messages are generated by the CyberScan TB1000 when it detects problems with the instrument operation.
When these messages are observed and if you do not understand the instructions shown below, contact the
Eutech Instruments Customer Services department to determine a resolution to the problem. An error message is
indicated by the instrument when an "E-0X" is displayed on the lower row of the display. The CyberScan TB1000
has five error codes, each assessing a different component or system of components in the instrument. The
following table lists the error messages and their associated meanings.

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 CyberScan TB1000 memory retains all original factory settings. At any time, you can force the instrument to
change back to these default settings. All calibration values and settable parameters (see section 5 & 6) will
change back to their original configurations. This is particularly useful if you feel that your calibration standards
may have been compromised. In this situation you may use the factory default parameters while waiting for new
standards to arrive from Eutech Instruments.
To invoke this option, first turn on the instrument. Next, press CAL key while holding down the ▲key. The
instrument will continue operating in normal automatic mode with all adjustable parameters reset to factory default
conditions.
8 Routine Maintenance
The CyberScan TB1000 has been designed for ease of use and simple operation. When not in use, ensure that
the instrument has been turned off and that a clean sample cuvette fitted with a black light shield cap has been
placed in the sample well. This will ensure that a minimal amount of dust and/or debris will be able to settle on
the optics of the instrument.
8.1 Cuvette Cleaning and Care
Proper measurement of the turbidity of a sample requires the use of a cuvette that is free of marks, smudges,
scratches and any bacterial growth. Cleaning the cuvette is accomplished by washing the interior and exterior of
the cuvette in a detergent solution. Once cleaned, the cuvette should be rinsed thoroughly 8 to 10 times with
clean distilled water to eliminate the possibility of detergent build-up and streaking. Cleaned and dried cuvettes
should be stored with the black light shield cap on the cuvette and can be stored in a cuvette rack (see
accessories and replacement parts list). During normal operation you may use any typical glass cleaner along
with a lint free cloth, or tissue, to clean the outside of the cuvettes.
8.2 Lamp Replacement
Periodically the lamp module will require replacement. Figure 1 illustrates the location of the lamp module. An
error message will be illuminated when it is time to replace the lamp (see section 7.2). It is recommended that
one spare lamp for each CyberScan TB1000 meter be kept on hand at all times to ensure continuous use of the
instrument.

Before replacing the lamp module ensure that the instrument is turned off. Once you have turned off the
instrument, proceed with the following instructions:
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. The new lamp module can now be connected to the instrument using the in-line power connector.
4. Feed the wire back into the instrument being careful that the wire does not get in the way of the lamp or
the lamp holder Z (on instrument). Make sure that the light bulb icon on the back of the lamp module is
upright. Press the module into the instrument until you hear it click firmly into place.
NOTE: The side tabs may need to be pressed outward until they click to secure the new lamp module.
5. If the two-side tabs on the lamp module do not click the lamp module securely in place, check that the
power wire is not obstructing the lamp module.
6. Turn on the instrument and follow the instructions in section 4.1 to re-calibrate the instrument with the new
lamp module. The instrument must be re-calibrated after lamp module replacement.
7. Resume normal operation.
8.3 Battery Replacement
The following instructions will guide you through the replacement of the batteries on the CyberScan
TB1000. Throughout this procedure DO NOT unplug the instrument. If the instrument is unplugged
during this procedure, all customer settings will be lost.
1. Turn the unit off.
2. Remove the lamp module by first pressing the side tabs inward and pulling the module out. Then unplug
the in-line lamp module connector by pulling the connector apart (see section 8.2 for complete details on
lamp replacement/removal).
3. Place the instrument upside down on a soft surface.
4. Remove the five screws and pull the bottom half of the instrument case away from the top portion of the
instrument case (NOTE: there is a center screw on the instrument that is located under the instruction
sheet).
5. Locate the two silver disc-shaped batteries in the separate battery holders on the left side closest to the
front of the instrument. Remove these old batteries by prying them slightly upward and sliding them out of
their holders.
6. Replace the old batteries with two coin-cell CR3032 batteries (Code No. EC-BATT3032). The positive side
of the batteries should be against the clip on the holder.
7. Replace the bottom half of the case making sure that the lamp module connector is fed through the lamp
module opening.
8. Replace the five screws, re-connect the lamp module to the instrument and insert the module into the lamp
module opening. (See Section 8.2).
9. Re-calibrate the instrument (see section 5.0) and then resume normal operation.
10. Dispose of used batteries in accordance with all Federal, state and local regulations.

10.1 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. This position
is the indexed position of the cuvette.
Nephelometric Turbidity Units (NTU): Unit of measure used when comparing the light scattered by a liquid media
to the light scattered by a known concentration of Formazin Polymer. This unit of measure is recognized as a
measure of the optical clarity of an aqueous sample. NTU is the accepted unit of measurement for turbidity.
Turbidity: 1) A measure of the attenuation of a radiant flux as it passes through a liquid media. 2) Optical clarity of
a liquid, 3) a phenomena caused by the presence of undissolved matter in liquid media.
