16 USER MANUAL11.9 Other practical notesIt is preferable to work with the same mass of the sample at each measurement tomeasure the size of the sample in a reproducible way. It is best to use the sameinstruments for the application of the sample.Put a sample on the pan as quickly as possible to avoid losing moisture.Temperature inside the chamber is much higher than outside, so the sample mayevaporate partly before measurement begins, which will result in a false result.When analysing the same substance quantity in successive measurements, use thesame tools to put a sample to be sure that samples are each time of the same size.Before putting a sample, tare a single-use pan and take it out of the chamber. Right afterputting a sample on the pan, place it inside the analyser chamber, close the chamber andpress START.Be sure that no dirt sticks under the pan, as it may increase sample weight and result infalse values.
