Blanking
Blanking is slightly different depending upon whether the
test format is a tablet test or liquid Tubetest. See "How to
Select and Perform a Test"
Blanking is not specifically mentioned in each test method
but it is important that the instrument has been correctly
"blanked" each time a test is carried out.

If a result is above the range
of the test a '>' symbol will
appear in front of the result.
In this case it will be necessary
mg/L
to dilute the sample with
N
deionised water and repeat
the test.
A dilution tube is available
from Palintest to simplify this.
Example for a x2 dilution:
Fill with sample to x2 line
and top up to 100 mL with
deionised water. Mix and use
this as the new blank and
sample for the test. Multiply
result by x2.
