Explosion hazard. An expired battery can cause hydrogen gas buildup
inside the instrument. Replace the battery before it expires. Do not
store the instrument for long periods with a battery installed.
Potential fire hazard. Use only alkaline or nickel metal hydride batteries (NiMH) in
the meter. Other battery types or incorrect installation can cause a fire. Never mix
battery types in the meter.
The battery compartment is not waterproof. If the battery compartment becomes
wet, remove and dry the batteries and dry the interior of the compartment. Check
the battery contacts for corrosion and clean them if necessary.
When using nickel metal hydride (NiMH) batteries, the battery icon will not
indicate a full charge after freshly charged batteries have been inserted (NiMH
batteries are 1.2 V versus 1.5 V for alkaline batteries). Even though the icon does
not indicate complete charge, 2300 mAH NiMH batteries will achieve 90% of
instrument operation lifetime (before recharge) versus new alkaline batteries.
To avoid potential damage to the meter from battery leakage, remove the meter
batteries prior to extended periods of non-use.
The meter can be powered with AA alkaline or rechargeable NiMH
batteries. To conserve battery life, the meter will power off after
10 minutes of inactivity, the backlight powers off after 30 seconds. This
time can be changed in the Power Management menu.
Note: Rechargeable batteries will only be recharged with the USB/power module.
Refer to the module documentation for further information.
For battery installation refer to Figure 3.

Turbidity measurement
W A R N I N G
Potential explosion and fire hazard. This turbidimeter is designed for water based
samples. Do not measure solvent or combustible based samples.
Readings can be taken with the Normal reading mode, Signal Average
mode or in the Rapidly Settling Turbidity mode. Refer to Reading modes
on page 17 for more information. For accurate turbidity readings use
clean sample cells and remove air bubbles (degassing).
Measurement notes
Proper measurement techniques are important in minimizing the effects
of instrument variation, stray light and air bubbles. Use the following
measurement notes for proper measurements.
Instrument
• Make sure that the meter is placed on a level, stationary surface
during the measurement.
Note: Do not hold the meter in the hand during measurement.
• Always close the sample compartment lid during measurement,
calibration and storage.
10
English
• Remove sample cell and batteries from the instrument if the
instrument is stored for an extended time period (more than a month).
• Keep the sample compartment lid closed to prevent the entry of dust
and dirt.
Sample cells
• Always cap the sample cell to prevent spillage of the sample into the
instrument.
• Always use clean sample cells in good condition. Dirty, scratched or
damaged cells can cause inaccurate readings.
• Make sure that cold samples do not “fog” the sample cell.
• Store sample cells filled with distilled or deionized water and cap
tightly.
Measurement
• Measure samples immediately to prevent temperature changes and
settling. Before a measurement is taken, always make sure that the
sample is homogeneous throughout.
• Avoid sample dilution when possible.
• Avoid operation in direct sunlight.
Turbidity measurement procedure
Note: Before a measurement is taken, always make sure that the sample is
homogeneous throughout.
1. Collect a
representative sample
in a clean container. Fill
a sample cell to the line
(about 15 mL). Take
care to handle the
sample cell by the top.
Cap the cell.
2. Wipe the cell with a
soft, lint-free cloth to
remove water spots and
fingerprints.
3. Apply a thin film of
silicone oil. Wipe with a
soft cloth to obtain an
even film over the entire
surface (Apply silicone
oil to a sample cell).
4. Push the Power key
to turn the meter on.
Place the instrument on
a flat, sturdy surface.
Note: Do not hold the
instrument while
making measurements.
5. Gently invert and
then insert the sample
cell in the instrument
cell compartment so the
diamond or orientation
mark aligns with the
raised orientation mark
in front of the cell
compartment. Close the
lid.
6. Push Read. The
display shows
Stabilizing then the
turbidity in NTU (FNU).
The result is shown and
stored automatically.
Additional information is

Calibration verification (Verify Cal)
The manufacturer recommends a calibration verification once a week.
After a calibration is complete, the meter automatically goes into the
Verify Cal mode.
Make sure that the sample cell is clean. Oil the sample cell with silicone
oil, refer to Apply silicone oil to a sample cell. Check the standard
solution. Prepare a formazin standard at the same value and read the
value.
1. Push Verify Cal to
enter the Verify menu.
4. Push Done to return
to the reading display.
Repeat the calibration
verification if the
verification failed.
2. Gently invert the
standard. Insert the
10.0 NTU (or other
defined value)

and close the lid.
3. Push Read. The
display shows
Stabilizing and then
shows the result and

Reading modes
1. Push the UP or DOWN key to enter the Reading Options menu.
2. Select Reading Mode to select one of the following options:
Option Description
Normal
(Default
setting)
Signal
Average
Rapidly
Settling
Turbidity
(RST)
The normal mode reads and averages three readings. The
result is shown after the reading.
The Signal Average mode compensates for reading
fluctuations caused by drifting of sample particles through
the light path.
The X-bar icon is shown on the display when signal
averaging is on.
The Signal Average mode measures 12 times and starts to
show the average after three readings. The final result is
the average of all 12 readings.
The Rapidly Settling Turbidity (RST) mode calculates and
continuously updates the turbidity reading of the sample to
™
a confidence of 95%, based on the accumulated trend of
the real time measured values.
The RST mode is best used on samples that settle rapidly
and continuously change in value. The reading is based on
a correctly prepared sample that is homogeneous at the
beginning of the reading. It is best applied to samples that
are greater than 20 NTU. The sample must be mixed
thoroughly by inversion immediately before inserting it into
the meter.
The target icon is shown on the display when the Rapidly
Settling Turbidity is on.
The Rapidly Settling Turbidity reads and calculates five
readings while showing intermediate results.
Apply silicone oil to a sample cell
Sample cells and caps must be extremely clean and free from significant
scratches. Apply a thin coating of silicone oil on the outside of the
sample cells to mask minor imperfections and scratches that may
contribute to light scattering.
Note: Use only the provided silicone oil. This silicone oil has the same refractive
index as the sample cell glass.
1. Clean the inside and
outside of the cells and
caps by washing with a
laboratory glass
cleaning detergent.
Follow with multiple
rinses with distilled or
demineralized water.
2. Apply a small bead
of silicone oil from the
top to the bottom of the
cell.
3. Use the provided
oiling cloth to spread
the oil uniformly. Wipe
off the excess so that
only a thin coat of oil is
left. Make sure that the
sample cell is almost
dry with little or no
visible oil.
Note: Store the oiling
cloth in a plastic
storage bag to keep the
cloth clean.
Indexing a single cell
Precise measurements for very low turbidity samples require the use of
a single cell for all measurements or optically matching the cells. Use
one cell to provide the best precision and repeatability. When one cell is
used, an index or orientation mark (other than the factory-placed
diamond) can be placed on the cell so it is inserted into the instrument
with the same orientation each time.
When using a single cell, make an index or orientation mark on the cell
as follows:
English
17
1. Fill the clean sample
cell to the line with high
quality water (<
0.5 NTU) and cap
immediately. Let the
sample cell degas for at
least five minutes.
2. Wipe with lint-free
cloth. Apply a thin film
of silicone oil (Apply
silicone oil to a sample
cell).
3. Push the POWER
key to turn the meter
on. Place the
instrument on a flat,
sturdy surface.
Note: Do not hold the
instrument while
making measurements.
4. Insert the sample
cell in the instrument
cell compartment so the
diamond or orientation
mark always aligns with
the raised orientation
mark in front of the cell
compartment. Close the
lid.
5. Push the UP and
DOWN key to access
the Reading Options
and then select
Indexing Sample Cell.
Note: The instruments
always stays in the last
selected reading mode.
6. Push Read. The
display shows
Stabilizing then the
turbidity in NTU. Record
the cell position in the
cell compartment and
the reading result.
7. Remove the cell,
rotate it slightly
approximately ⅛ of a
turn and insert it again
into the cell
compartment. Close the
lid.
18 English
8. Push Read. Record
the cell position in the
cell compartment and
the reading result.
9. Repeat step 6 until
the lowest reading is
shown. Place an
orientation mark on the
cell marking band near
the top of the cell so the
cell can be consistently
inserted in the position
that yields the lowest
reading.
