Quick Start
1. Check the instrument calibration. See page 22 for instructions.
2. Thoroughly clean the ring, block, block holder, and sample cup with
acetone.
3. Turn on the power and let the machine run for 15 minutes.
4. Place the test block in the holder. Do not let the ring and block touch.
5. Mix the test uid for at least ten minutes.
6. Set the motor speed to 60 rpm. See page 7 for more information
about using the Control Panel.
7. Fill the cup with uid and place it on the stand.
8. Raise the cup until the ring and block assembly are fully submerged.
Tighten the thumb screw.
9. Wait for the torque reading to stabilize. Then zero the torque reading on
the control panel.
10. Position the torque arm so it is inside the torque arm clamp.
11. Turn the torque adjust handle so the gauge reads 150 in-lb.
12. Zero the time on the control panel.
13. Let the machine run for 5 minutes.
14. Record the torque reading from the display screen.
15. Release the pressure on the ring and block.
16. Lower the cup and discard the uid.
17. Thoroughly clean the ring, block, block holder, and sample cup with
acetone.
18. Calculate the Lubricity Coefcient =
19. See page 11 for more information about calculating the Correction
Factor and the Lubricity Coefcient.
