6.11 Live Testing Screen
Once a test has begun, a real-time display of current values will be presented. The
user may view a live chart at any time by pressing the LIVE CHART tab button
located at the top of the screen. Printing can be done at any time by selecting the
ADVANCED CHART & PRINTING OPTIONS button (Please note that a printer
must be connected to the instrument before trying to print.). This button will also
enable the user to view detailed test information and streaming numerical data. The
user can also create custom header and footer segments of the printed plot. Pressing
the EXIT button returns the user to the RUN TIME MENU shown below.
6.11.1 Automatic Shutdown
The instrument is equipped with an automatic consistency or SGS shutdown and
alarm. Use the up/down arrows to select the set point at which the alarm should
occur. Pushing the Shutdown Type button allows one to select either type of alarm.
If the Auto Shutdown feature is ON, the instrument will automatically stop the test
when the indicated alarm value is reached. In addition to stopping the test,
automatic shutdown will also turn the heater and motor off and the cooling water
on. Note that the Auto Shutdown Alarm is in addition to the alarm values entered in
test setup that are printed with each plot. In addition to the automatic consistency
shutdown there is a timed shutdown. It is necessary to select the number of hours
from the drop-down box that is required for a timed shutdown. SGS alarms greater
than 600 lbf/100 ft

may allow the test to show the break of the SGS bond to the
slurry cup causing the graph to fluctuate down to zero. The consistency alarm unit
is Bc and the SGS unit is lbf/100 ft

.
6.11.2 Stopping a Test
To stop the current test, the user must press the STOP TEST button on the RUN-
TIME MENU screen. Once the test has been stopped, no further data will be
logged and no further temperature or pressure control will be provided. The
software will save the current test in a file on the instrument’s local hard disk. The
default location is C: /Fann/Tests. If auto-shutdown is enabled, the test will be
stopped when the Consistency Alarm value has been reached. This action has the
same effect as the user pressing the STOP TEST button; however it also turns the
motor and heater off and the cooling water on. Note that there is a 5-10 second
delay from the time a consistency alarm is triggered until automatic shutdown
occurs. This is to prevent noise or spikes in the consistency signal from triggering
automatic shutdown prematurely.
6.12 View Test
The view test button allows the user to access previously completed test data. The
data may be viewed either graphically or in spread sheet format, customized,
