TESTING SAMPLES WITH THE
miniAV-LT AUTOMATIC
VISCOMETER
This chapter of the manual will provide information on testing samples
using the miniAV-LT. Observe the safety cautions noted in the introduc-
tory chapter when operating equipment. The miniAV-LT should only be
operated by qualified personnel.
Turning on the miniAV-LT
Turn on the miniAV-LT Bath Unit using the power switch on the power
supply unit.
Testing samples
Loading software 1. Turn on the computer and load the miniAV-LT software by double-
clicking the VISCPRO ® icon on the Desktop.
NOTES If the software is already loaded, use your computer mouse to click Main
from the menu bar and click Poll for Instruments from the Main menu
options. This will establish communications between the computer and
the on-line instrument.
2. Pour sample material into the glass vial(s). For 20 mL vials, fill only
half full, as the viscometer tube will displace sample in the vial.
Approximately 10 mL of sample
should be sufficient for testing.
NOTES Do not overfill the vials. Sample overflow
may create problems for the tube cleaning
cycle.
You should periodically test calibration
check standards per your established
laboratory procedures. Recalibrate the
miniAV-LT (see Chapter 3, Calibration) if
result variance warrants.
3. Place the sample vial in the holder
underneath the viscometer tube.
4. Raise the holder until the magnetic
coupling engages (see photo image).
The viscometer tube tip will be
touching the bottom of the sample
vial.
