Additional rights are shown on the above screen. Check the box to assign the user rights in each case.
Push the OK button, and the next screen allows you to assign a password with up to 10 alphanumeric
characters:

This password is necessary for the user to gain access to the assigned features when using the
instrument.
Once users have been set up by the Administrator, turn off the RST Rheometer. The next time the
instrument is turned on, the first screen to appear is User Names. This occurs because the User
Management feature is active. Use the Down Arrow to see the menu of users who have been assigned to
this instrument. Choose the appropriate user name, enter the password and then push OK to go to the
main screen. The name for the current user will appear on the menu bar at the left top of the main screen.
III.6 Edit Program
This allows the user to create a multiple step test for a detailed and comprehensive evaluation of a sample
material. For example, it is possible to perform a controlled stress ramp to determine the yield stress, then
a flow curve to characterize viscosity vs. shear rate, and finally, a creep/recovery test to measure residual
flow and relaxation after the shearing action stops.
There are analysis functions that permit the use of QC limits for viscosity values during the rtest and math
models which show the minimum, maximum and average viscosity values. There is a “Reports” function
that tells how the data is to be stored after the test.
Click the “Edit” button on the main screen. Then click the “Edit Program” button on the next screen:
