8 Measurement
Caution:
• Before any measurements are performed, check the
resistance of all materials in contact with the sample
• Materials in contact with the sample are:
- PTFE (pump piston, filling tube)
- Borosilicate glass (measuring cell, pump cylinder)
• Before performing any measurements, prepare suitable
cleaning agents or solvents.
Information:
• The sample has to be filled into the measuring cell free of
any bubbles. Bubbles seriously interfere with the
measurement.
Possible sources of bubbles are:
- Leakage at the connection of the filling tube or the screw
plug.
- Gas bubbles contained in the sample.
• The measuring cell has to be completely filled.
• The sample temperature should not be lower than the
ambient temperature.
• Carefully clean the measuring cell after each series of
measurements to avoid deposit of coatings.
• The displayed temperature value is flashing as long as the
temperature of the filled sample exceeds the temperature
specification of the DMA 35
N
(0 to 40 °C). Measuring
results will be displayed, but it is recommended to wait
until the temperature display stops flashing.
• The flashing temperature unit (°C or °F) indicates the
proper functioning of the instrument.
