Operation
The CAV 4.2 can be operated in either local or remote mode through a pair of software
programs. In Local Mode, the CAV 4.2 GUI software programcontrols the instrument, while in
Remote Mode a separate computer with the VISCPRO II software program installed controls it.
Each of these programs is independent of the other and maintains its own data set, where a
data set consists of a run of tests, test results and error logs. Common instrument settings,
method templates, and equipment status are shared between the programs.
The operating status of the CAV 4.2 is shown on the left-most button of the main screen menu
of the CAV 4.2 GUI. This button toggles between Local Mode and Remote Mode. A green icon
indicates that the instrument is connected to VISCPRO II. In Remote Mode, the Users, Results,
and Errors action buttons are grayed to indicate that instrument operation cannot be
managed from the CAV 4.2 GUI.

Calibrate viscometer tube (VISCPRO II)
Viscometer tube calibration values are associated with specific temperatures, so calibration
must be performed when operating a CAV® 4.2 bath at a new temperature. Once a tube is
calibrated at a particular temperature, the C and E constants are saved by the instrument and
will be recalled if that tube is set to run at that temperature again.
1. Assemble a set of standard oils with known kinematic viscosities. Use at least different
two standards for each bulb to be calibrated. The CAV 4.2 is designed to run "thin"
standards (those with viscosities less than 10X the lower limit of the viscometer tube) in
two bulbs, while "thick" standards (those with viscosities greater than 10x the lower limit
of the viscometer tube) run in only the lower bulb.
2. Follow the procedures in Run a sample test to prepare, load, and run all of the
calibration standards as method Verify Known KV.
3. When all tests have completed, from the VISCPRO II Menu, select Configure >
5. Select the date range from which to retrieve appropriate test data.
6. Select the sample entries to use for calibration. You must select at least two entries or
the software will not recalculate the constants.
• Shift-left-click—to select a contiguous range of entries.
• Ctrl-left-click—to select multiple entries.

7. Click Calculate new constants. The new C and E constants display in their respective
fields.
• Evaluate the accuracy of the new calibration constants for each standard by
comparing the Known Viscosity with the Calculated Viscosity. This difference is
displayed as a percentage in the % Difference column. You can repeat the calibration
by selecting other sample entries.
• Check Limit E Constant before calculating constants to limit the E constant to no
more than 10000.
8. When the new calibration constants are acceptable, click Update bulb to save the C and
E constants and calibration data to the local database and update the C & E constants in
the registry of the CAV® 4.2.
Method/Test settings
Method templates are stored in the registry of the CAV® 4.2. When an instance of VISCPRO II
connects with a CAV® 4.2, those method templates are pushed to VISCPRO II. Any changes
made to the method templates in VISCPRO II are synchronized with the CAV® 4.2. No
method templates are permanently stored with VISCPRO II.
All method templates have the same set of fields. However, when the Verify Known KV method
is applied to a sample test, the Check Standard KV value is added to the information set for
that test. The Verify Known KV method must be used when running sample test for
calibration.
• For CAV 4.2 GUI: navigate to the appropriate Bath Screen, click Methods.

Maintenance and Service
Update CAV 4.2 software and firmware
Software and firmware code updates may occasionally need to be manually installed on the
CAV 4.2 user-interface, controller boards, and controlling PCs. There are four types of code
that can be installed:
• UI updater: this software is actually the complete UI updater program (UpdateUI.exe)
that runs on the CAV 4.2. It is used to install the UI software and firmware updates. It is
updated by copying it over the existing UpdateUI.exe.
• CAV 4.2 GUI software: this software is the CAV 4.2 user-interface. To update the CAV 4.2
GUI software, you must be logged out of the user-interface and running the UI updater
instead.
• Firmware updates: this code controls the baths, sample handlers, and valve controls. It is
installed directly onto the respective controller boards using the UI updater.
• VISCPRO II: this software is installed on the controlling PC.
Tools and materials required
The following tools and materials are required to update the software and firmware:
USB Type A-Male to Mini B cable (6ft)
To prepare the USB flash drive
A USB flash drive must be loaded with the software and firmware to be updated.
1. On a PC, download the update packages from the CANNON website:
2. Unpack and copy the update files to the USB flash drive. Only one set of files can be on
the USB flash drive during an update.

Adjust solvent dosing chamber sensors
Each CAV® 4.2 bath has its own solvent dosing chamber, mounted on the side panel. Optical
sensors on the inlet and the outlet of the dosing chasing must be adjusted to "see" the solvents
that are drawn past them.
When the chamber is full of solvent, adjust the sensors by turning the set screws counterclockwise until the associated green light turns on. When running multiple solvents, verify
each solvent, always adjusting by turning the screws counter-clockwise.
