Levelling the Rheometer
Optimum performance depends upon the instrument being level and in a sturdy position to avoid the possibil-
ity of rocking. To check and see whether your instrument is level, simply place a bubble spirit level
on the lower
temperature module plate .
If the instrument is not level, screw the adjustable feet (located at each corner of the instrument) either in or out,
as necessary. Check the spirit level after each adjustment. Once you have the instrument levelled correctly,
press each corner of the instrument to check that all four feet are in contact with the laboratory bench. Any
movement caused by pressing should be rectified by adjusting the feet, and then rechecking the level of the plate.
If the spirit level is the circular type, it should be placed in the middle of the plate. If the spirit level is the bar
type, place it along a diameter of the plate. Check the level by placing it along another diameter of the plate at
90° to the first position.
Checking Your System
After installation has been completed, start the instrument to check to make sure everything is working and that
all parts of the system are communicating with each other. Use the following steps to check your system:
1. Turn on the air supply to the instrument.
2. Turn on the water supply to the instrument.
3. Remove the air-bearing clamp.
4. Turn on all electrical parts of the system (rheometer, PC, etc.). A system check will be initiated as shown by
the LCD on the electronics control box.
5. Start the rheology software.
6. Select the Instrument Status screen in the software.
7. If everything is installed correctly, the instrument will display continually updating figures.
8. Lower the head using the buttons in the software. If the installation is OK, the head will operate.
9. Input a temperature slightly different to that displayed. If the installation is OK, the temperature will
change to the new one you have just input.
10. Raise the head.
If all of these actions result in the correct response, you can be confident that you have installed the system
correctly and it is ready for use. If you have problems, please contact your local TA Instruments office or their
appointed agent.
