TESTING SAMPLES WITH THE
miniPV Series
This chapter of the manual will provide information on testing samples
using the miniPV Series. Observe the safety cautions noted in the
introductory chapter when operating equipment. The miniPV Series
should only be operated by qualified personnel.
Turning on the miniPV Series
Turn on the miniPV Series Bath Unit using the power switch on the
power supply unit.
Testing samples
Loading software 1. Turn on the computer and load the miniPV Series 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.
Approximately 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 estab-
lished laboratory procedures. Recalibrate the miniPV
Series (see
Chapter 3, Calibration) if result variance warrants.
3. Place the sample vials in the carousel.
4 Check the thermometer in the temperature bath to
make sure the bath is holding the proper tempera-
ture. If necessary, calibrate the miniPV Series
temperature control probe using the temperature
calibration procedure in Chapter 3.
