Cup resists attachment and detachment from Cup Holder.

Likely Cause:  Dried sample material in and around the Cup Holder.
Solution:  Clean thoroughly with steel wool.

Likely Cause:  Bur has formed on Cup's camlock groove.
Solution:  File bur off.

Like Cause:  Cup is bent.
Solution:  Replace with a new cup immediately.




Sprindle Housing tracks poorly.

Likely Cause:
  Sample material on Slide.
Solution:  Clean thoroughly with stiff brush.

Torque Overload LED is on and sounder is making noise.

Likely Cause:
Emergency Stop button has been pushed.
Solution: Deactivate Emergency Stop button by pushing on it and rotating it counterclockwise.

Likely Cause: Full scale torque has been reached.
Solution: Switch viscometer off for at least two seconds, then on again.

Viscosity and/or Torque values are off 30-5%.

Likely Cause:
Incorrect spindle ratio.
Solution: Confirm what RPM option was installed on your viscometer.

Located on top of the spindle housing you will see a pulley. If the pulley has 3 screws, your viscometer is set to go 6600 RPM. If the pulley has 2 screws, your viscometer is set to go 8800 RPM.

In WinShear under the SETTINGS menu, select MACHINE. If your viscometer is 6600 RPM, enter the spindle ratio of 2. If your viscometer is 8800 RPM, enter the spindle ratio of 3.
