TESTING SAMPLES WITH THE
miniQV-X AUTOMATIC VISCOMETER
This chapter of the manual will provide information on testing samples
using the miniQV-X. Observe the safety cautions noted in the introduc-
tory chapter when operating equipment. The miniQV-X should only be
operated by qualified personnel.
Turning on the miniQV-X
Turn on the miniQV-X Bath Unit using the power switch on the power
supply unit.
Testing samples
Loading software 1. Turn on the computer and load the miniQV-X software by double-
clicking the VISCPRO ® II 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.
Permit the bath to stabilize at test temperature before testing samples.
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. Approxi-
mately 10 mL of sample should be
sufficient for testing in either bulb of
the viscometer.
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
miniQV-X (see Chapter 3, Calibration) if
result variance warrants.
3. Place the sample vials in the
carousel.
