- Click on the Tune Tab in the Master Panel.
- Set the tune high and low frequency according to the cantilevers being used and the
application. For general tapping mode cantilevers:
- Low = 50 kHz
- High = 400 kHz
- Set the Target Amplitude to 1.0 V.
- Set Target Percent to -5%
- Click Autotune.
- It is possible that it will not allow autotune if the laser is misaligned.
- If this happens, realign the laser and deflection.
- Cross check the frequency of the cantilever being used (listed on box), and check
that the autotune plot looks similar to the one below.
- If the plot is drastically off, this could mean one of the following:
- The cantilever is seated incorrectly.
- The laser is misaligned.
- The cantilever is very degraded and should be replaced.
- Try adjusting the laser first, then seating before changing the cantilever. If there
are still issues after replacing the cantilever, contact ACMAL staff.
