At “Amplitude = xx”, look across the tip of the stir/freeze wire
from the side to view and estimate the sample stir vibration ampli-
tude. 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. Pressing > increases the stir amplitude; pressing <
decreases the stir amplitude.
Press ENTER to store the new setting (or STOP to restore the orig-
inal setting).
6. 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:
a. Press CLEAR to clear the entire setting and display the present
format.
b. Use < to toggle to the date format you require (“mm/dd/yyyy”
or “dd/mm/yyyy”).
c. Use > to toggle to “24hr” format, “am”, or “pm”, as required.
d. Enter the current date and time (including zeros), via the numer-
ic keypad, one digit at a time from left to right.
e. Press ENTER to store the new setting (or STOP to restore the
original setting). If an invalid setting is attempted, the instru-
ment will reject the setting and beep when ENTER is pressed.
7. Select Beeper
The 4C3 keypad in itself has no audible indication that a button has
been adequately pressed. The “Select Beeper” menu item enables an
audible indication.
