NOTE: If only the large sample cell is to be used, it is not necessary to recalibrate the small and
micro cells. Similarly, if only the small cell is to be used, it is not necessary to calibrate the micro
cell.
If the sample is analyzed at a temperature different by more than 4°C from that used to calibrate the
instrument, the MULTIPYCNOMETER should be recalibrated at the new temperature.
