Connecting the eQCM 15M to an incorrect and unsafe voltage can create a safety hazard (see Chapter 1
for details).
Environmental Considerations
The eQCM 15M is a very sensitive instrument capable of measuring ng/cm
electrode face. Therefore, special consideration of the environment will help ensure you are acquiring the best
data possible. Minimize or eliminate vibrations or sudden movements during data-acquisition.
Likewise, keep temperature fluctuations to a minimum. Changes in temperature and the rate of change of
temperature both cause frequency-drift during data-acquisition. If you are planning very long experiments, a
temperature-controlled chamber may be necessary to reduce drift. Leaving the crystal holder in solution for
some period of time prior to starting your experiment will help reduce unwanted frequency changes.
