TEST METHODS SPECIFICATIONS
INTRODUCTION
Chlorine dioxide is used as a substiture for and an adjunct to chlorine in
water treatment. It is better than chlorine in eliminating taste and odor in
certain cases. Chlorine dioxide, unlike chlorine, does not produce carcinogenic
chlorinated organic compounds when reacted with organic materials. A
disadvantage is the higher cost of producing chlorine dioxide compared to
chlorine.
APPLICATION
Drinking and pool waters; domestic and industrial wastewater.
RANGE
0 to 7.0 ppm Chlorine Dioxide
METHOD
Chlorine dioxide reacts with DPD to form a red color in proportion to the
concentration.
HANDLING & PRESERVATION
Test as soon as possible to avoid loss of chlorine dioxide.
INTERFERENCES
Chlorine interference is eliminated by the addition of glycine to the sample
before the indicator.

before each test and the same tube should be used for the blank and the
reacted sample.
NOTE: For the best possible results, carry a reagent blank through the
procedure. After scanning the blank, perform the test procedure on clear,
colorless, distilled or deioized water. Subtract results of regent blank from all
subsequent test results.
CAUTION: DO NOT leave reacted DPD samples in test tubes (0290). Discard
sample and thoroughly rinse tubes. If allowed to remain, DPD will stain tubes,
significantly impairing the operation of the colorimeter. If necessary, acid
wash, and vigorously clean glassware with test tube brush and detergent.
CALIBRATION
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
standard should be similar to the expected concentration of the sample that
will be tested.
Prepare a chlorine standard 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 chlorine dioxide).

WATERLINK CONNECT
The meter may be interfaced with any Windows-based 64 bit computer
by using the LaMotte WaterLink Connect program and a USB cable. The
program will store test information and results in a local database, and allow
for exporting this data to a comma separated value (CSV) file. The meter
will send the following data: time/date stamp, name of test, sample value,
sample units, meter name, and location. To download WaterLink go to
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 rubber 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 6 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.
Storing the meter above ambient room temperature will decrease the battery
charge more quickly than storage at room temperature. If the meter does
not turn on, it means that the battery is at a very low charge. Charging the
battery with the wall adapter in this state may take up to 10 hours. At low
temperatures, approaching 0 °C, the battery will charge more slowly. It will not
charge at all below 0 °C. 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
www. .com [e-mail]1.800.561.8187

20
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. When the battery icon simultaneously flashes bars 1 and 2
followed by bars 3 and 4, it is an indication that the battery is damaged and
technical support should be contacted.
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 at a moderate temperature.
• Fully charge the battery before storing the unit for extended periods
of time.
• Fully charge the battery at least once per year. Failure to do so may
result in a permanently drained battery.
• Limit backlight use. The unit consumes 3X normal power with the
backlight on. Set the backlight time option to 10 seconds, or select
“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
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.

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
sample. The keypad is used to make menu selections that are viewed on the
display.
