These continuation programs have their own

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.
