Train Sensors (VISCPRO II)
Train the sensors whenever the CAV 4.2 bath is to operate at a new temperature. Once trained, the
calibration values for a particular temperature are saved and will be recalled if the CAV 4.2 is set to run
at that temperature again. Retraining for a particular temperature is only necessary when the
viscometer tube is changed or if sensor performance changes over time.
Note:
Sensor training uses
Test
and
Advanced
settings from the default
method, but
Default Wash
settings.
1.
Insert an empty vial into position 1 of the carousel for the bath to be trained.
2.
Fill a vial with a test solution that has a viscosity approximately 3 times higher than the lower
viscosity limit of the ubbelohde tube. Insert the vial into position 2.
3.
In the
VISCPRO II Menu
, select
Service > [
instrument group
] > [
instrument
] > Train viscometer
tube sensors
. The
Train viscometer tube sensors
window opens.
4.
(Optional) Check
Prewash
to run a wash cycle prior to training sensors.
5.
(Optional) Check
Trip Points Only
to skip adjusting the power levels of the sensors.
6.
Click
Start
.
7.
When training is complete, repeat this procedure for the second bath if necessary.
Run a Wash (VISCPRO II)
When necessary, washes may be run independent of a sample test.
1.
In the
VISCPRO II Menu
, select
Service > [
instrument group
] > [
instrument
] > Wash viscometer
tube.
2.
Select the tube to wash.
3.
Select whether to use wash parameters from the last sample run or use default wash parameters.
4.
The initial cup evacuation can be bypassed by checking the appropriate box.
5.
Click
Begin Wash
.
Run a Sample Test (VISCPRO II)
This procedure details how to run and configure various kinematic viscosity tests on the CAV 4.2 using
VISCPRO II software.
1.
Verify that the CAV 4.2 is running and has achieved steady-state temperature in each bath to be
used.
•
The status window displays
IDLE
. During warmup,
SEEKING TEMPERATURE
will be displayed.
