OPERATING PRINCIPLE
The YSI 9300 direct-reading photometer is an instrument that measures color
intensity. Light is passed through a test tube containing the sample solution, and
then through a colored filter onto a photodetector. Filters have been chosen so that
light of a specific wavelength is selected. When the solution is completely colorless,
all of the light passes through the sample. With colored samples, light is absorbed
and that which passes through the sample is proportionately reduced.
In 9300 test procedures, the direct-reading photometer is used to m eas ure the colo r
which is produced when chemical reagents are reacted with the sample. In these
tests, the color intensity produced is proportional to the concentration of the
parameter under test.
The photometer is pre-programmed with calibrations for each test parameter.
Different test procedures are carried out at different wavelengths to optimize the
sensitivity of each test. The required wavelength is selected automatically by
the instrument.
The calibrations are accessed by entering a unique program number at the
start of each test procedure. This enables the instrument to select the
appropriate wavelength filter automatically and allows the photodiode
response to be converted to a concentration reading. The instrument thus
displays a direct-reading
The photometer is ideally suited for general analytical applications. The
instrument can be used as a laboratory or field photometer for standard
analytical methods or for comparison of colored solutions.
of the test result.
For general analytical applications, Transmittance (test program 0), or
Absorbance (test program 1) can be chosen.

Power Supply
The photometer is designed to operate on alkaline batteries.
The photometer features a battery indicator – see ‘System Mode’ functions and scroll
down to Battery Level. A minimum voltage of 3.0V is needed to operate the
photometer.
In addition to the above feature, a battery-warning message will appear automatically
on the display when the battery voltage becomes low. The batteries should be
replaced as soon as possible after the warning message appears.
Replacing the Batteries
The battery compartment in the base of the instrument is secured by four screws.
To replace the batteries, remove the screws (set aside), remove the cover and
install the batteries, observing the correct polarity as indicated. Use 3 x 1.5V 'AA’
alkaline batteries.
To avoid potential corrosion damage, remove batteries from the instrument if it is to
be stored or left unused for a long period of time (> 30 days).
GENERAL PHOTOMETER OPERATION
The photometer is controlled by a simple intuitive menu system.
The highlight indicates the active line or section of the screen.
The and keys move the highlight through the menu choices.
The and keys allow selection of options.
The flashing cursor in the ‘options menu’ at the bottom of the screen
indicates the action which will occur if the [OK] button is pressed.
Operating Modes
The photometer has two distinct operating modes - the PHOTOMETER mode
and the SYSTEM mode.
The PHOTOMETER mode is the normal operating mode for taking photometer
readings. This mode is engaged automatically when the instrument is turned on
by pressing the key.
In order to conserve battery life the photometer will switch off automatically
after 5 minutes of non-use.
The SYSTEM mode is used to set the system options. This mode is engaged
when the photometer is turned on using the key and then selecting 'System'
using the
and keys and pressing [OK].

and keys to select the options.
• Press [OK] to accept the selections and return to PHOTOMETER mode.
Back Light
The graphic display features a backlight to enhance the display contrast. This
may be switched off to conserve battery power.
Language Options
The photometer can be operated in a number of different languages. When a
particular language is selected, the test names and operating commands will
appear in that language. Certain tests and unit options are provided in
accordance with the conventions of particular countries and are only available
when the photometer is switched to the language concerned. Select the
language required from English, French, German, Spanish or Italian.
Units
The photometer offers the choice of result expressed in mg/l, ppm, mmol/l,
µmol and g/l.
Battery Level
A battery level indicates the remaining battery life. At least 3.0V is required for
successful operation of the instrument.
TAKING PHOTOMETER READINGS
The photometer is very simple to use. Intuitive screen prompts guide the user
towards the test result.
Program Numbers and Test Instructions
Each test is identified by a separate program number or named key. Program
numbers are shown in test instruction sheets supplied with the instrument or
reagent systems. For some tests, a choice of different programs is offered in
order to give the option of the result in different forms (eg for Nitrate - NO
Nitrate Nitrogen - NO
-N).

In certain methods, the test can be continued to a further stage - for example
in the tests free chlorine and total chlorine. This is accomplished in the
programming of the photometer. In these tests, once the first stage result is
obtained, the ‘Follow-On’ option may be selected to progress the test to the
next program stage or stages and the result will be calculated automatically.
These continuation programs have their own program number for reference
purposes although direct access to these programs may be restricted.
Blank and Sample Tubes
A BLANK TUBE is needed each time the photometer is used. This enables the
instrument to be set automatically and compensates for any inherent color in
the test sample.
The BLANK TUBE is a test tube filled only
with the sample being tested. It is
important to use the actual sample to be tested to provide a true comparison
for the test results.
The term 'SAMPLE TUBE' is used to describe the tube containing the sample
the reagents which have been added in accordance with the appropriate
and
test instructions. This tube is used to take the photometer reading.
Light Cap
A light cap is provided with the photometer. This cap fits over the test chamber
and prevents excess light from reaching the photodiode.
It is not
necessary to use the light cap when using the photometer indoors or
under shaded outdoor light. The light cap should however be used when
working outdoors in strong sunlight. The light cap is also recommended when
carrying out turbidity-based tests such as the cyanuric acid test, under bright
or variable lighting conditions. Test instructions indicate when the light cap
should be used.
Getting the Best Results
Success in obtaining accurate and consistent test results will depend on the
care with which test procedures are carried out. Always follow the test
instructions carefully and observe the stated standing periods and temperature
conditions where applicable.
Wipe test tubes free from condensation before placing in the photometer. Test
tubes should always be kept in a clean condition. Wash and dry carefully after
use. Dirty tubes may be soaked in weak detergent solution if necessary.
Tubes which become stained or scratched in use should be replaced.
