NOTES
To reduce the chance of separating the mercury column during the heating
phase of the temperature profile, you may wish to initially remove the
calibrated thermometer from the CMRV unit. Store the thermometer in a
vertical position. You may replace the calibrated thermometer when the
CMRV has cooled to 30°C or lower. If the thermometer is not in place
during CMRV-4500 cooling, you should seal the thermometer well in the
block and the thermometer hole in the Plexiglas
®
cover with stoppers,
particularly when the humidity of the ambient air is high. This will help
prevent frost buildup on the surface of the block and enhance temperature
control.
Be sure the thread is properly wound around each rotor and the Plexiglas
®
cover is in place on top of the CMRV-4500 before proceeding with the test.
Cell calibration test procedure
Cell calibration
Use the VISCPRO
®
software to input calibration information as follows:
1. Load the VISCPRO software and make certain that the MRV instru-
ment is listed on a button bar at the bottom of the Primary Window.
If it is not, click Poll for Instruments from the Main menu to
establish computer contact with the CMRV unit.
2. Click Service/Calibrate Cell Constants. The Calibration Param-
eters window will open.
3. Click the Temperature field and select the desired calibration
temperature from the drop-down options.
4. Click the Mass field and select the correct value for the test mass.
5. Click the Known
Viscosity field and input
the known viscosity of
the standard at the
calibration temperature
in centipoise (mPa·s).
6. Click the Calibrate ...
button to open the
Calibrate Cell Con-
stants window. The
CMRV-4500 will cool to
the desired calibration
temperature and main-
tain the temperature for
one hour. When the
instrument has com-
pleted the calibration
profile, the Status field
in the Calibrate Cell
Constants window will
indicate Ready to Calibrate.
