TESTING SAMPLES WITH THE
CANNON AUTOMATIC VISCOMETER
This chapter of the manual will provide information on testing samples
using the CAV-2100 or CAV-2200 instruments. Observe the safety
cautions noted in the introductory chapter when operating equipment.
The CAV should only be operated by qualified personnel.
Preparing the CAV
Turning on the CAV 1. If CAV power is off, turn on the CAV Bath Unit by rotating the red
power switch on the control panel clockwise. Provide power to the
CSU Service Unit (rear panel On/Off switch) and the Solvent Dis-
pensing Unit (front panel On/Off switch).
NOTE If it is necessary to
cut power to the CAV
Bath Unit, press the
power switch IN.
Preparing sample trays
Sample trays will
slide into place along
the grooved track in
the sample table.
Plated steel vial
adaptors should be
placed in the circular
recesses in the tray.
Glass sample vials slide into the adaptors. To position the first sample
vial under the viscometer tube in preparation for testing, slide the tray
forward until the detente mechanism engages. A heated sample tray
should snap into position against the detent mechanism when the front of
the tray extends approximately 2 centimeters (3/4”) over the edge of the
sample table. The forward edge of an unheated tray will be indented
approximately 2.2 centimeters (7/8”). During sample testing, trays are
automatically advanced by the pneumatic system.
Electrical connections
For heated sample trays, verify that the attached three-pin tray cable is
connected to the interior wall connector above the sample table.
Using a temperature probe
A recessed thermometer well at the front of the sample tray permits
insertion of a temperature probe to monitor tray temperature.
