6. Enter the following information in the general block data:

a. Viscosity Standard Name (e.g. B11000)

b. Lot Number

c. Expiration Date

e. Viscosity Value

f. Spindle Serial Number

7. Upon test completion, click the Analysis button. The average viscosity of each step will ap-

pear in the bottom window.

8. An average viscosity reading should be within ±3% of the standard’s stated viscosity value at

the appropriate temperature.

B.5.3 Troubleshooting

Check each of the items below if your measured values fall outside the range of uncertainty:

a. Assure that the gap is set properly.

b. Assure that the temperature is set properly.

c. Assure that correct amount of calibration fluid is present and the gap is filled properly.

d. Assure that correct spindle constants are being used.

e. Assure that the rheometer has been zero calibrated.

Error Messages

Message

Cause

Solution

Range Error

User input a value less than

the allowed minimum value

or greater than the allowed

maximum value (Speed or

Torque)

Check values. The R/S will advise

the maximum and minimum values

when this error is displayed.

Zero Cal. Error!

An unacceptable value was

measured during the zero

point calibration.

Ensure the spindle is not mounted to

the R/S. Re-try zero calibration. If

this fails, call for service.

ABORT: Speed Max!

Fluid is too thin to be run

at requested Shear Stress/

Torque level. Alternatively, no

fluid is present.

This should not happen following the

proceding procedure.
