Important:
• 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.
Hints:
• 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
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.
