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.
The recommended stir amplitude adjustment procedure may be
found in Chapter 5, Troubleshooting and Service. Pressing >
increases the stir amplitude; pressing < decreases the stir ampli-
tude.
3. Press ENTER to store the new setting (or STOP to restore the
original setting).
5. Set Date/Time
This menu item enables changing the date/time format and resetting the
date and time.
At “Set Date/Time”, press START to display the current date and time.
Any change must be made in this order:

3. Press CLEAR to clear the entire setting.
