Setup
System Test
1. Turn the unit on. The power switch is located on the front panel.
2. If the heater is raised, lower it using the “Heater Lift/Lower” switch.
The sample cup is already attached to the viscometer in order to protect
the bob shaft during shipping. Always handle the bob shaft carefully;
bending it will result in poor viscosity readings.
3. To remove the sample cup, unscrew the sample cup nut and pull the
sample cup straight down.
4. Carefully apply a thin coating of high-temperature thread lubricant (#165-
44-2) to the bob shaft threads.
5. To install the bob, slide it onto the bob shaft with the tapered end down
and screw it securely into place. An R1B1 bob/rotor combination is
standard for the Model 1100 Viscometer, however other combinations are
available. See page 5 for more information.
