M3600 Stand-Alone Operation
When the M3600 is first powered on, a welcome screen is
displayed:
Followed by the main menu:
The Main Menu
1. Go –
Once you have entered test steps (through the “Setup” menu),
pressing 1 will start the test.
2. Setup –
Pressing 2 will display the Test Setup screen:
Enter the parameters for the Time, Temperature,
and rotational Speed for the first step of your test.
When you have finished, press the
Next/Enter button
to go to the next step. When you have finished creating steps,
press
Next/Enter twice
to return to the main menu.
(Note: If
temperature control is not necessary for your test, enter any
value; e.g. “70.0” into the TEMP field in order to
proceed.)
3. Review –
Once you have set up and run a test, pressing 3 allows you to
review the test results. Press
Next/Enter to
cycle forward through the test steps until you reach the last
one, at which point pressing
Next/Enter returns
you to the main menu. (Note: the
Stop/Back button
is disabled when reviewing test results.)
The test results screen:
4. RobBob
– This menu allows you to specify which rotor sleeve and bob you
wish to use for your test:
Press 1 to select rotor sleeve 1 with bob 1. (This is the
default setting for the M3600.)
Press 2 to select rotor sleeve 2 with bob 2, press 3 to select rotor
sleeve 3 with bob 1.
Press 4 to select rotor sleeve 1 with bob 2, press 5 to select rotor
sleeve 1 with bob 5.
Press 6 to select rotor sleeve 1 with bob 4.
5. and 6. RPM1 and RPM2 – These menus allow you
to immediately run some standard pre-programmed tests. Please note
that none of these tests allow for temperature control.
RPM1:
RPM2:
7. Test – This menu allows you to run one-touch API tests,
which have been pre-programmed (these also do not allow for
temperature control):
8. Calib – This brings up the Calibration menu for the M3600:
Pressing
1 will
display the Stress Calibration screen:
|
 |
WARNING:
Be sure to use exactly
130 ml of
calibration fluid and to position the stage height
correctly before attempting calibration, or damage
to the bob shaft bearings may result. |
Fill the sample cup with 130 ml of calibration fluid and place
the sample cup on the stage. Raise the stage until the sleeve
is immersed in the calibration fluid, so that the fluid in the
sample cup reaches the scribed line on the rotor sleeve.
When
you have positioned the stage at the correct height, secure the
stage position by tightening the thumbscrew.
Enter the viscosity parameter of the calibration fluid and press
Next/Enter to
start calibration.
Note: Once
the stress calibration process has begun,
it
cannot be stopped,
and will last for approximately one minute.
If you make a mistake when entering the viscosity parameter of
the calibration fluid or if there is a physical problem with the
calibration procedure (not enough or too much fluid, for
example), the M3600 will display this warning:
If
this error occurs, check to see that you are entering the
correct viscosity parameter for the calibration fluid you are
using, and try again.
On the Calibration menu, Button 2 accesses
the Temperature calibration menu, and should only be used
by trained Grace Instrument technicians.
Pre-programmed Tests
As mentioned earlier (button 7), the M3600 includes
pre-programmed API tests. The parameters for these tests are
listed below:

Post-test cleanup
Four
components should always be cleaned following a test:
Sample
cup, Temperature probe, Sleeve, and Bob.
-
Loosen the thumbscrew and lower the stage to the bottom
position.
-
Remove the sample cup and
temperature probe for cleaning
-
Remove the sleeve by turning
it clockwise (looking downward from the top) while holding the
rotor
-
To remove the bob, turn it
clockwise with one hand while holding onto the anti-climber with
the other hand to keep it from falling downward.
|
|
NOTE:
After every test, you should remove the bob and clean it
thoroughly, in order to prevent the bob from adhering to the
bob shaft. |
