The error message will provide some detail about the alarm condition. The test and data collection will continue
while the Warning message is displayed. The audible alarm will continue to sound until the operator touches the
OK button within the Warning box. The Running Viscosity Test display will show a colored box around the data
parameter associated with the Global Alarm. When the alarm condition is first met, the colored box will be yellow. If
the measurement parameter returns to the acceptable range, then the colored box will be removed. When the alarm
condition is met a second time, the colored box will be red (see Figure V-9). The audible alarm will only sound once.
TIP: The Global Alarm sound can be turned off in the Sounds menu of User Settings. The Global Alarm is
deactivated by choosing None in the drop-down list of available measurement parameters. You must press OK to
confirm your Global Alarm choice.
Spindle List
The selection of Spindle in Configure Viscosity Test can be done by using either a number pad or a scroll list. (This
choice is selected through the navigation button in the Set Spindle screen.) The contents of the scroll list are defined
in the Spindle List menu. Each spindle can be individually selected or deselected using a check box. Spindles, shown
with both their name and their number, are listed numerically according to their spindle entry number.
The restricted spindle will not appear on the scroll list of available spindles when choosing Spindle in Configure
Viscosity Test. If the user selects to enter the spindle by number, then the choice of a restricted spindle will present
an Invalid Input message and prevent the selection of the spindle (see Figure 5-10).
