If the readings are significantly above or
below the expected results, consider the
following:
Sample contains more than one dissolved
solid. For example, if the sample contains
both salt and sugar, a Brix refractometer
will not display the true sugar content
because the salt content will skew the brix
measurement.
When diluting samples, be sure to use a
pure solution such as distilled water.
Sample contains suspended solids. Filter
and thoroughly mix the sample before
testing.
Perform a calibration.
Replace the battery.
Outside light can cause erratic readings,
make sure to close the
on the
during measurement.
After about 3000 tests, turn the unit off for
5 to 10 minutes to rest the battery.
