Verification
The following two test units are available:
Verification kit Turbi Zero (~ 0 FNU)
Verification kit Turbi Low (~ 5 FNU)
The test unit consists of a cover with a bayonet lock and a cylinder
with 3 plain areas on it. The plain areas are arranged at an angle of
90°.
The test unit is calibrated for a sample temperature of 25 °C. If your
sample has a temperature other than 25 °C, you have to measure
the sample temperature externally and convert the nominal value to
the corresponding temperature. The variation is +0.3 to + 0.4% per
°C. That means, the lower the temperature, the smaller the scatter-
ing.
If the deviation of the measured value is larger than ±10% com-
pared to the nominal value of the test unit, try again. If the deviation
is again too large, clean the measuring chamber, see
Measuring Chamber, p.
36.
