3. TEST PROCEDURES
Blanks and Samples
Palintest photometers use a BLANK tube to set the
instrument to blank and a SAMPLE tube to take the
reading.
A BLANK tube is a test tube filled with untreated
water sample. A SAMPLE tube is a test tube
containing the sample to which reagents have been
added in accordance with the test procedure
described.
The blank setting is held in memory. It is not
necessary to reset the blank each time a reading is
taken if the water samples are similar and the
conditions of use are the same. The blank setting
can be confirmed if necessary by taking a test
reading on the blank tube.
For detailed instructions on individual test
methods, consult the Palintest photometer
methods instructions
4. INSTRUMENT OPERATION
4.1. Palintest 7500 Photometer
This set of instructions is a quick guide to using
your photometer. For more details on the full range
of functions that are available on your 7500
4.1.1 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.
4.1.2 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 use. The switch off
period is five minutes in normal use, but may be
adjusted in System mode.
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].
Scroll through the menu box to view all the options
available.
4.1.3 Taking Photometer Readings
The photometer is very simple to use. Screen
prompts guide the user towards the test result. The
following sections describe how to get the best out
of the system.
4.1.4 Program Numbers and Test
Instructions
Each test is identified by a separate program
number or named key. Program numbers are
shown in Palintest photometer methods
instructions.
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 - NO3or Nitrate
Nitrogen - NO3-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 allowed for 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. 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.
4.1.5 Sample Dilution
The photometer has a sample dilution option. This
enables a factor to be entered when samples have
been diluted to bring them within the measuring
range of the test. For example if a five times dilution
of the sample has been made, then the dilution
factor x5 should be entered. The photometer will
multiply the observed result by this factor so that
the correct result for the original sample is
displayed.
This option may be used in conjunction with the
Palintest Dilution Tube which enables dilutions of
x2, x3, x4, x5 and x10 to be made; or with Palintest
syringes which enable higher dilutions factors.
Higher dilution factors may be entered subject to
the limitation of the number of digits available on
the result display for each test. When the display
capabilities are exceeded, the symbol [xxx] will
appear on the result display.
The sample should not be diluted prior to carrying
out a pH test, or Transmittance or Absorbance
reading.
4.1.6 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
tubes 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.
