VI.6.1 Utilities
→ Zero calibration
The function “Zero Calibration” serves to calibrate the zero point of the rheometer. This function
continues for approximately 10 minutes and should be done once a week.
Before starting this function, be sure the R/S+ Rheometer has warmed up
for at least 10 minutes and that NO measuring element (spindle or bob)
is in the measuring element coupling.
To confi rm the command that the measuring system is removed, press the OK key (start of zero
point calibration), or press the ST key to return to the Utilities menu.
Zero point calibration will proceed automatically and comprises several measuring series at
different speeds. The progress of calibration is shown by the number of executed steps of the
total steps. If an error message appears during zero calibration, repeat the zero calibration. If
the error message is displayed again, there may be a technical fault (see Appendix G: Warranty
and Repair Service).
After a successful calibration, the values of the zero point are stored internally. These values are
preserved until the next calibration.
Press the OK key to save the values. Press any other key to return to the Utilities menu without
saving.
Note: You can cancel zero point calibration at any time with the ST key. The zero point values
determined up to that point will be ignored.
VI.6.2 Utilities
→ Edit Program
This function allows the input of new programs and the modifi cation of existing programs. These
programs may be run after a successful creation via the menu level “Program Measurement” in
the main menu.
The following values are user-defi nable in a program:
• measuring system to be used
• number of steps
• start and end value of each step
• number of measurement points for each step
• duration of each step
