1.0  OBJECTIVE:

To lay down the operating procedure of Viscometer.

2.0  SCOPE:

This shall be applicable to the Viscometer of Quality Control Instrument Laboratory.

3.0  RESPONSIBILITY:

3.1  Technical Assistant/ Helper.

3.2  Q.C Analyst.

4.0  ACCOUNTABILITY:

6.0  PROCEDURE:

6.1   Level the viscometer using the bolts on the legs of the instrument.

6.2  Insert the spindle guard.

6.3  Insert the spindle by very carefully holding the viscometer side and screwing the spindle in a counterclockwise direction.

6.4  Carefully lower the viscometer into the solution to be measured using the mounting nut on the viscometer handle. Insert up to the insertion marking on the spindle.

6.5  Check to make sure the viscometer is still level.

6.6  Turn the viscometer on the set to the desired speed (the combination of spindle and speed should not cause the torque reading to exceed 100%).

6.7  Wait several rotations for the reading to stabilize and mark the torque by pressing down on the clutch lever.

6.8  Turn off the motor when the needle is in front of the view window and read the scale.

6.9  Calculate torque by multiplying the factor found on the card by the unit.  Use the “LV” and the appropriate spindle number.  Spindle numbers are stamped on the top of the shaft.

6.10    Clean up and unplug viscometer after use according to the SOP No. BM/QCE_C/SOP017-00.
