4. Set Stir Amplitude
This menu item displays the current sample stir amplitude setting and
allows the setting to be changed.
1. At “ Set Stir Amplitude ” , press START to display “ Amplitude =
xxx ” .
2. At “ Amplitude = xxx ” , look across the tip of the stir/freeze wire
from the side to view and estimate the sample stir vibration
amplitude. If properly adjusted, the stir/freeze wire should
vibrate principally fore and aft and should never strike the probe.

tude.
