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.
