Acceptable keypad input is indicated audibly with a short beep. Unac-
ceptable keypad input is indicated audibly with a longer tone.
Remote operation (computer-controlled)
Local/Remote operation of the CAV is selected via the RMT/LOC button
on the control panel. Pressing the button will toggle between the Remote
and Local operation modes. The Remote mode option permits automatic
control of CAV functions via the VISCPRO
® controlling software.
Remote mode offers the advantage of multi-drop, multi-sample automatic
testing for up to 100 samples depending on tray type. Sample data is
automatically stored to the VISCPRO
® database for future reporting/data
collection. Additionally, several reports (analyses) may be used to
calculate and display kinematic viscosity and viscosity index (VI) values.
See the chapters on VISCPRO
® analyses for further information.
All analyses provide a dynamic operation mode which can immediately
display and transmit test results to your computer screen, printer, and/or
serial port for in-house data collection. See Chapter 6 for more informa-
tion on configuring analyses.
To select Remote mode operation, press the Remote/Local (RMT/LOC)
button on the keypad on the Bath Unit until the front panel vacuum
fluorescent display indicates REMOTE operation. If the display does not
indicate REMOTE operation, then the instrument is in Local mode.
NOTE Remote mode may only be selected when the CAV is idle.
Setting temperature
To set the temperature in Remote mode, load the VISCPRO ® software
and click Configuration. Select the CAV from the list of available
instruments and click Tray Settings: Tube and Bath. Select the desired
tube and type the desired temperature in the Bath Temp: field. Accept-
able values are any numbers between 20°C and 100°C (150°C for CAV
high-temperature models). If necessary, you may use the decimal point
key to input temperature to the nearest 0.01°C. Press OK to save the
temperature setting.
NOTE To cancel temperature selection before completing the procedure, click
Cancel.
After the target temperature has been set, the CAV bath temperature will
be adjusted to the target temperature and the bath will equilibrate at the
test temperature. When the instrument has attained a temperature within
0.05°C of the target temperature, the current bath temperature will be
displayed in large type on the display for CAV-2100 models.
NOTE Placing the instrument in Remote mode while the VISCPRO software is
loaded will reset the bath temperature(s) to match the VISCPRO set-
tings.
