5. At the end of the test, record the sample
probe resistance and the bin number, and
then press STOP. The display will
change to “Probe Bin Test”.
To set the correct sample bin number, fol-
low steps 6-8.
If the current sample bin number matches
the number just recorded, press STOP
twice to exit the menu.
6. Press SETUP. The Supervisor/Operator
keyswitch must be in the Supervisor posi-
tion.
Note: If you have a 4D3 cryoscope with a
suffix before “C”, the menu item “Set
Sample Bin #” is within the TEST
menu, not the SETUP menu.
7. At “Select Setup Item”, press < or > to
select “Select Sample Bin #”, and then
press START.
8. If the current sample bin number is not
the same as the one recorded in step 5,
enter the correct number, press ENTER,
and then press STOP twice to exit the
menu.
Block Bin Setting
1. Turn off the power and unplug the instru-
ment. Remove the cover and record the
block probe bin number located on the
block probe wire.
2. Replace the cover. Plug in the instrument
and turn it on. If there is a Supervisor/
Operator keyswitch, turn it to the
Supervisor position (if required).
3. At “Press START to Continue”, press
SETUP.
Note: If you have a 4D3 cryoscope with a
suffix before “C”, the menu item “Set
Block Bin #” is within the TEST menu,
not the SETUP menu.
4. At “Select Setup Item”, press < or > to
select “Select Block Bin #”, and then
press START.
5. Enter the correct number and then press
ENTER.
6. Press STOP to exit the menu.
Stir Amplitude
1. Turn on the instrument. If there is a
Supervisor/Operator keyswitch, turn it to
the Supervisor position (if required).
2. Press SETUP. Press < or > to select “Set
Stir Amplitude”, and then press START.
3. Watch the vibration blur at the tip of the
stir/freeze wire. If the amplitude is not
within the range specified below, press >
to increase the amplitude, or press < to
decrease the amplitude. (The default is
98, but your value may differ.)
3D3 The stir wire movement should be
no wider than the width of the sam-
ple probe.
4D3 The stir wire movement should be
twice the width of the sample
probe.
4. Check the setting by placing a sample
(water or standard solution) in position on
the probe. If bubbles form in the sample,
or if the stir wire hits the tube, the current
setting is too high and must be adjusted
downward.
5. When the setting is correct, record the
new stir amplutide number for your
records, and press ENTER.
