Lutron WA-300 User manual

  • Hello! I've reviewed the user manual for the Lutron Water Tester WA-300. This document provides instructions on how to use the device to measure water conductivity, check filter conditions, and understand various water quality parameters. I'm ready to assist with any questions you might have about its features operation or usage.
  • What does the tester measure?
    What is the measurement range of the tester?
    What does "LOBAT" on the display mean?

1. GENERAL & PRINCIPAL
* The quality of the water is getting much more concerned
by the human being and it also an important factor in the
industrial sectors, laboratories or other fields.
*In industrial sectors, it would be a great help for the quality
of the products if using the good water ( more pure water )
in the process.
*It also may be the cause of many diseases if home drink
water contain impurities & existing high conductivity.
*Under above conditions, this Pure Water Tester ( Water
Quality Tester) are designed to check the purity of water
(water conductivity) also can determine the condition of the
" Water Filter " easily and rapidly.
* This tester is used to measure the conductivity value
(ranging from 0 - 2000 uS) which can therefore judge
whether water is pure or not. The conductivity value will
become lower if there is much less impurities existed in
water (for example, distilled water that its purity is higher
than others will get a lower conductivity value of approx.
< 10 uS).
*Besides, many people always take many kinds of procedures
on water treatment by install the different kinds of
equipment, such as filter or purifier to improve the quality
of water. However, most of people do not know whether
the procedures or filter is effective and can con- tribute to
the quality of water. General speaking, the impurities will
be filtered out if the water process procedures attain the
expected result, thus we can use this instrument to measure
the conductivity value of purified water and to judge the
effect of the filter (or water process procedures).

4. APPLICATION
* Water conditioning, aquariums, beverage,
fish hatcheries, food processing, photography,
laboratory, paper industry, plating industry,
quality control, school & college.
* Check the condition of the water filter.
5. MEASURING PROCEDURE
5-1 Check the filter condition
1) Power on the meter.
Hold the Sensor Handle (3-4, Fig. 1) by hand & let the
Sensor Probe (3-5, Fig. 1) is immersed wholly into the
measuring water, then the Display (3-1, Fig. 1) will
show the conductivity values (uS).
2) First check the reading values ( uS ) for the water not
make the treatment ( not via the FILTER ), then record
the reading value
4
3)Secondary check the reading values ( uS ) for the water
that already make the treatment ( after the FILTER ),
ref. Fig. 3.
4)If the water quality already be improved, then the reading
values should be change with a certain values, other wise
the FILTER is dirty or not under the normal condition.

5-2 Check the water's conductivity (water condition)
1) Power on the meter.
2)Hold the Sensor Handle (3-4, Fig. 1) by hand & let the
Sensor Probe (3-5, Fig. 1) is immersed wholly into the
measuring water refer Fig. 4, then the Display (3-1, Fig. 1)
will show the conductivity values (uS).

3)* If the water is pure, then the meter will display the low
conductivity values, typically. For example the distill
water conductivity value will approx. less than 10 uS.
* If the water contain the impurity, then the meter will
show the high conductivity typically.
* From the different water's conductivity value, user can
juge the water quality condition.
( Due to drinking mineral water contain the mineral
material, when measure the mineral water if the meter
display the high conductivity value, it is normal.)
6. MEASURING CONSIDERATION
* The water's conductivity value should be less
within a reasonable values after the "FILTER"
be installed, otherwise the filter is not under
normal condition.
* The conductivity of the pure water will be low
value.
* If the water's conductivity is high, then the
water quality may have some problem.
(When test " Drinking Mineral Water " , the meter may
show the high conductivity value, it is normal)
*
After make the water pure treatment process,
then conductivity value should less.

7. REPLACEMENT OF BATTERY
1)When the left corner of LCD display show "LOBAT", it
indicate a normal battery output of less than 6.5 V - 7.5 V.
It is necessary to replace the battery, However
in-spec. measurement may still be made for several
hours after " Low Battery Indicator " appears before the
instrument become inaccurate.
2)Open the " Battery Cover " (3-3. Fig 1) and remove the
battery.
3)Replace with 9V battery and reinstall the cover.
