TEST METHODS SPECIFICATIONS
APPLICATION
Drinking water supplies and distribution systems, swimming pool and
spas, sewage and chlorinated waste waters, process waters and sanitizing
solutions.
RANGE
0 to 4.0 ppm Chlorine (may be extended by dilution)
0 to 7.0 ppm Bromine (may be extended by dilution)
METHOD
In the absence of Iodide, Free Available Chlorine reacts instantly with the
buffered diethyl-p-phenylenediamine indicator (DPD) to produce a pink-red
color in proportion to the amount of chlorine present. Subsequent addition of
potassium iodide produces a rapid color response from the combined forms
of chlorine (chloramines). In buffered samples, bromine reacts with disthylp-phenylene diamine (DPD) to produce a pink-red color in proportion to the
concentration of bromine present.
HANDLING & PRESERVATION
Chlorine and bromine in aqueous solutions, particularly weak solutions, are
not stable. Exposure to sunlight or agitation will accelerate the reduction of
chlorine and bromine. For chlorine samples, fill sample containers to the top
and cap tightly. Analyze samples as soon as possible after collection. Samples
to be analyzed for bromine cannot be preserved or stored.
INTERFERENCES
The only interfering substance likely to be encountered is oxidized
manganese. The extent of this interference can be determined by treating a
sample with sodium arsenite to destroy the chlorine or bromine present, so
that the amount of interference can be estimated. Chlorine, bromine, and
iodine will give a positive result and should be considered an interference
unless the test is being performed specifically for that parameter.
CALIBRATION
The colorimeter is precalibrated. In order to comply with NPDWR or NPDES
reporting regulations, the calibration should be checked periodically by using
a set of reference standards including a 0 mg/L blank and 0.3, 1.0, and 3.5
mg/L chlorine. To prepare these standards, a LaMotte 1000 mg/L standard
chlorine equivalent solution (Code 3858) is available. Consult with your local
regulatory agency to determine standardization frequency.

Levels of chlorine about 6 mg/L will cause a bleaching effect on the DPD
indicator, and may give a false indication that no chlorine is present. If if is
possible that the chlorine concentration is greater than 6 mg/L, perform test
on a diluted sample and multiply the result by appropriate dilution factor.
CAUTION: DO NOT leave reacted samples in test tubes. Discard sample and
thoroughly rinse tubes. If allowed to remain, DPD wil stain tubes, signigicantly
impairing the operation of the colorimeter. If necessary, acid wash, and
vigorously clean glassware with test tube brush and detergent.
NOTE: For the most accurate results, samples over 6 ppm chlorine should be
diluted with chlorine demand free water and re-tested.
NOTE: The meter will remember the last scanned blank reading. It is not
necessary to scan a blank each time the test is performed. To use the
previous blank reading, instead of scanning a new one, scroll to Scan Sample
and proceed. For the most accurate results, the meter should be blanked
before each test and the same tube should be used for the blank and the
reacted sample.

CALIBRATION
CHLORINE STANDARDS
The meter should be calibrated with free chlorine standards. The calibration
should be done with a distilled or deionized water blank and one chlorine
standard of known concentration. The concentration of the calibration
Calibration
standard should be similar to the expected concentration of the sample that
will be tested.
To perform a bromine calibration, prepare a bromine with a concentration
that is equivenlent to a chlorine dioxide standard that is within the range of
the chlorine dioxide test. (1 ppm chlorine = 1.9 ppm bromine). Follow the
procedure below but select the bromine test.

BATTERY
BATTERY/AC OPERATION
The colorimeter may be operated on battery power, using a USB wall adapter
or USB computer connection. If using the meter as a bench top unit, use the
wall adapter if possible to extend the battery life. The meter will remain on
when the USB adapter is used.
To charge the battery with the wall adapter, plug the smaller end of the USB
cable (USB mini B connector) into the meter and the larger end of the USB
cable (USB Type A connector) into the wall adapter. Plug the wall adapter into
an AC outlet. Reinsert the USB port plug after charging.
To charge the battery from a computer, plug the smaller end of the USB cable
(USB mini B connector) into the meter and the larger end of the USB cable
(USB Type A connector) into a USB port on a computer.
The battery icon will show no bars and flash when the unit first turns on. Then
the indicator will indicate the battery status by showing 0, 1, 2, 3 or 4 bars.
It will take 5 hours to fully charge a low battery. The battery icon will flash
when the battery is charging. The battery icon will show four bars and stop
flashing when it is fully charged. The charging circuit will automatically switch
to a float charge when the battery is fully charged. The charger may remain
connected. Some computers will NOT supply power to their USB ports during
standby operation. The wall adapter will charge the unit continuously.
The battery icon will show no bars and continuously flash if the battery is
getting low but the unit will still operate normally. A “Low Battery” message on
the status bar of the display will replace the time when the battery voltage is
too low for proper operation and accuracy may be degraded. A “Shutdown Low
Batt” message on the display will appear for a few seconds before the power
is switched off when the battery is too low to operate the unit.
To extend the battery life:
• Shut down the unit with the power switch when not taking
measurements or use the power save option to have the unit
automatically turn off after 5 minutes.
• Store the unit in a cool dry place.
• Fully charge the battery before storing the unit for extended periods
of time.
• Limit backlight use. The unit consumes 3X normal power with the
backlight on. Set the backlight time option to 10 seconds, or select
21
Page 22
“Button Control” and keep the backlight off.
BATTERY REPLACEMENT
The lithium ion battery used in this unit should last for many years with
normal use. When it no longer powers the unit long enough to meet testing
requirements it will need to be replaced. Lithium ion batteries that are
properly charged and stored do not usually lose all capacity; they just have
less capacity after hundreds of charge cycles. This unit uses a custom battery
assembly that is only available from LaMotte Company. Battery replacement
must be performed at a LaMotte authorized repair facility. The water resistant
housing of this meter should not be opened by the user. Contact LaMotte
Company by phone (1-800-344-3100) or email (tech@lamotte.com) for a
return authorization number.
MAINTENANCE
CLEANING
Clean the exterior housing with a damp, lint-free cloth. Do not allow water
to enter the light chamber or any other parts of the meter. To clean the
light chamber and optics area, point a can of compressed air into the light
chamber and blow the pressurized air into the light chamber. Use a cotton
swab dampened with Windex® window cleaner to gently swab the interior of
the chamber. Do not use alcohol; it will leave a thin residue over the optics
when dry.
REPAIRS
Should it be necessary to return the meter for repair or servicing, pack the
meter carefully in a suitable container with adequate packing material. A
return authorization number must be obtained from LaMotte Company by
calling 800-344-3100 (US only) or 410-778-3100, faxing 410-778-6394,
or emailing tech@lamotte.com. Often a problem can be resolved over the
phone or by email. If a return of the meter is necessary, attach a letter with
the return authorization number, meter serial number, a brief description of
problem and contact information including phone and FAX numbers to the
shipping carton. This information will enable the service department to make
the required repairs more efficiently.

GENERAL OPERATING INFORMATION
OVERVIEW
The meter is a portable, microprocessor controlled, direct reading colorimeter.
It has a graphical liquid crystal display and 6 button keypad. These allow the
user to select options from the menu driven software, to directly read test
results or to review stored results of previous tests in the data logger. The
menus can be displayed in seven different languages.
The LaMotte tests are precalibrated for LaMotte reagent systems.
The colorimeter displays the result of these tests directly in units of
concentration.
The optics feature a colored LED. The LED has a corresponding silicon
photoiode with an integrated interference filter. The interference filter selects
a narrow band of light from the corresponding LED for the colorimetric
measurements.
A USB wall adapter, USB computer connection or lithium battery powers the
colorimeter.
GENERAL OPERATING INFORMATION
The operation of the colorimeter is controlled by the menu driven software
and user interface. A menu is a list of choices. This allows a selection of
various tasks for the colorieter to perform, such as scan blank and scan

header displays the title of the current menu. The footer line displays the
time and the date, the data logger status and the battery status. The menu
selection window is in the middle of the display between the header and the
footer.
The menu selection window displays information in two general formats. In
the first format only menu selections are displayed. Up to 4 lines of menu
selections may be displayed. If more selections are available they can be
viewed by pressing the arrow buttons to scroll the other menu
selections into the menu selection window. Think of the menu selections as
a vertical list in the display that moves up or down each time an arrow button
is pressed. Some menus in the colorimeter are looping menus.
The top and bottom menu choices are connected in a loop. Scrolling down
past the bottom of the menu will lead to the top of the menu. Scrolling up
past the top of the menu will lead to the bottom of the menu.

TUBES AND CHAMBERS
The colorimeter uses one type of tube (Code 0290) for all test factors.
The handling of the tubes is of utmost importance. Tubes must be clean and
free from lint, fingerprints, dried spills and significant scratches, especially
the central zone between the bottom and the sample line.
Scratches, fingerprints and water droplets on the tube can cause stray light
interference leading to inaccurate results. Tubes that have been scratched in
the light zone through excessive use should be discarded and replaced with
new ones.
Tubes should always be washed on the inside and outside with mild detergent
prior to use to remove dirt or fingerprints. The tubes should be allowed to airdry in an inverted position to prevent dust from entering the tubes. Dry tubes
should be stored with the caps on to prevent contamination.
After a tube has been filled and capped, it should be held by the cap and the
outside surface should be wiped with a clean, lint-free absorbent cloth until it
is dry and smudge-free. Handling the tube only by the cap will avoid problems
from fingerprints. Always set the clean tube aside on a clean surface that will
not contaminate the tube. It is imperative that the tubes and light chamber be
clean and dry. The outside of the tubes should be dried with a clean, lint-free
cloth or disposable wipe before they are placed in the meter chamber.
Tubes should be emptied and cleaned as soon as possible after reading a
sample to prevent deposition of particulates on the inside of the tubes.
Variability in the geometry of the glassware and technique is the predominate
cause of variability in results. Slight variations in wall thickness and the
diameter of the tubes may lead to slight variations in the test results. To
eliminate this error the tubes should be placed in the chamber with the same
orientation each time.
Chambers which have been scratched through excessive use should be
discarded and replaced with a new one.
SAMPLE DILUTION TECHNIQUES
If a test result is out of the range of the meter, it must be diluted. The test
should then be repeated on the diluted sample. The following table gives quick
reference guidelines for dilutions of various proportions.
Amount of Sample Deionized Water to Bring
Final Volume to 10 mL
10 mL 0 mL 1
5 mL 5 mL 2
2.5 mL 7.5 mL 4
1 mL 9 mL 10
0.5 mL 9.5 mL 20
All dilutions are based on a final volume of 10 mL, so several dilutions will
require small volumes of the water sample. Graduated pipets should be
used for all dilutions. If volumetric glassware is not available, dilutions can
27
Multiplication Factor
Page 28
be made with the colorimeter tube. Fill the tube to the 10 mL line with the
sample and then transfer it to another container. Add 10 mL volumes of
deionized water to the container and mix. Transfer 10 mL of the diluted
sample to the colorimeter tube and follow the test procedure. Repeat the
dilution and testing procedures until the result falls within the range of the
calibration. Multiply the test result by the dilution factor. For example, if 10 mL
of the sample water is diluted with three 10 mL volumes of deionized water,
the dilution factor is four. The test result of the diluted sample should be
multiplied by four.
