TEST METHODS SPECIFICATIONS
INTRODUCTION
The most common mineral forms of sulfur are iron sulfide, lead sulfide, zinc
sulfide, calcium sulfate and magnesium sulfate. In most fresh waters, the
sulfate ion is the second or third most abundant anion, being exceeded only
by bicarbonate and, in some cases, silicate. Sulfur, in the form of sulfate, is
considered an important nutrient element. Mineral springs are rich in sulfate
and feed appreciable quantities of this compound to the watershed. Acid mine
water drainage is a form of pollution which may contribute extremely large
amounts of sulfate content to natural waters. Other sources of sulfate include
waste material from pulp mills, steel mills, food processing operations and
municipal wastes. Many bacteria obtain sulfur from sulfate for the synthesis
of amino acids. In lakes and streams low in oxygen, this process of sulfate
reduction causes the production of hydrogen sulfide, with its characteristic
offensive odor. Calcium sulfate and magnesium sulfate contribute
significantly to the hardness of water. Under natural conditions, the quantities
ordinarily to be expected in lakes are between 3 and 30 parts per million.
APPLICATION
Drinking and surface; domestic and industrial wastes.
RANGE
0 to 100 ppm Sulfate
METHOD
Sulfate ion is precipitated in an acid medium with barium chloride to form a
barium sulfate suspension in proportion to the amount of sulfate present.
HANDLING & PRESERVATION
Sulfate samples may be preserved by refrigeration at 4°C up to 7 days in glass
or plastic containers without any change in concentration.
INTERFERENCES
Suspended matter and color interference may be removed by a filtration step.
Silica in excess of 500 mg/L will interfere.

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.
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.
CALIBRATION
STANDARDS
The meter should be calibrated with sulfate standards. The calibration should
be done with a distilled or deionized water blank and one sulfate standard of
known concentration. The concentration of the calibration standard should be
similar to the expected concentration of the sample that will be tested.
CALIBRATION PROCEDURE
1. Press and briefly hold to

WATERLINK CONNECT 2
The meter may be interfaced with any Windows-based 64-bit computer
by using the LaMotte WaterLink Connect 2 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: name of test, sample value, sample units, time/
date stamp, and meter name. To download WaterLink Connect 2 go to http://
softwarecenter.lamotte.com/. Select “WaterLink Connect 2 FREE Download”.
BATTERY
BATTERY/AC OPERATION
The meter 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 lithium ion 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. Failure
to insert the USB port plug when the meter is not connected to a computer
by USB or actively charging by USB could result in damage to internal
components.
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. Reinsert the USB port
plug after charging. Failure to insert the USB port plug when the meter is not
connected to a computer by USB or actively charging by USB could result in
damage to internal components.
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,

20
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 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 life of the battery:
• 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 three times the normal power
when the backlight is 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. Contact LaMotte
Company by phone [phone]) or email ([email protected]) 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.
