guide provided with the instrument. Please refer to your instrument instruction manual and the diagram at the end of
this document, Figure 4.
Note: Once the instrument and VISCPRO II are successfully installed, a calibration
must be performed at the wash temperature and each temperature at which the
user wishes to run samples.
Preparing the miniAV Series for Testing
Calibrate the miniAV Instrument
Temperature calibration is essential for the proper operation of the miniAV after installation. The calibration process
consists of sending a temperature and its offset to the instrument, then waiting for the temperature to equilibrate.
Equilibration is complete when the instrument stays within 0.02 °C for 150 seconds. To calibrate temperature on the
miniAV series, follow the instructions below.
Note: It is necessary to log in as a manager to complete the calibration.
1. Click Configure from the primary display and select Instrument Settings from the Configure options for the
desired instrument.
2. Click Tray Settings: Tube and Bath option.
3. Enter the temperature you wish to calibrate in the Bath Temp input box and then press OK to save new target
temperature.
4. Click Service from the primary display and select your desired instrument.
5. Click Temperature Calibration option. The Temperature Calibration Data window will open.
Note: The value in the Calibration Temperature box should display the
temperature the user selected in the tray settings.
6. Place your reference thermometer inside the bath.
7. Wait for the machine to equilibrate at the desired temperature.
8. Enter the current temperature reading to the nearest 0.01 °C from the reference thermometer into the Reference
Temperature display window as shown in Figure 2.
Figure 2: Reference Temperature Window
9. Click the Apply as Current Offset option button (always click the radio button for the Apply as Current Offset

unless directed otherwise by a CANNON service engineer).
10. Click the Calibrate button and wait for the machine equilibrate using the offset.
11. Repeat this entire process for each temperature at which the user wishes to run samples.
Occasionally a temperature may require several calibrations in order to get an accurate calibration. The General Bath
Offset is a factory-preset value affecting temperature control at all temperatures and should not be changed.
Once all desired running temperatures have been calibrated, the user must train the tube sensors at each of these
temperatures.
Train the Tube Sensors
MiniAV series tube sensors must be trained in order for the instrument to properly perform test functions. To train the
miniAV series sensors, follow the instructions below.
Note: Depending on the security level settings, it may be necessary for you to log
in as a manager to complete the calibration.
1. To train tube sensors, click Service from the primary display and select the Train Tube Sensors option for the
desired instrument. This opens the Train Tube Sensors window as shown in Figure 3.
Figure 3: Train Tube Sensors Window
2. Wait for the machine to equilibrate at the desired temperature.
3. Click the Train at Wash Temperature checkbox if wash temperature training is desired.
Select the desired training parameters as follows:
•Prewash: Click the Prewash option if the tube is not clean and dry. VISCPRO will initiate a cleaning cycle using
current wash configuration settings prior to initiating the sensor training procedure.
Note: The instruction panel will instruct you to insert an empty vial in order to
perform the prewash.
4. Raise the empty vial to enable the Start button. Or, for the miniAV-X, place in position 2.
5. Click the Start button.
After the prewash is complete, the instrument will then obtain the voltages for each sensor at each of the specified
temperatures.
The instruction panel will then instruct you to insert a vial containing an oil with a viscosity three times the lower limit
of the tube and raise it into the ready position for determining trip points.
Once all voltages and trip points have been obtained for all desired temperatures, the tube sensors have been trained.

3. 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.
Caution: Do not overfill the sample vials as sample overflow may create
problems for the tube cleaning cycle.
4. Place the sample vial in the holder underneath the viscometer tube.
5. Raise the holder until the magnetic coupling engages. The viscometer tube tip will be touching the bottom of the
sample vial. Refer to Figure 5.
