4.5.1 Displays Overview
Channel displays are available before initialization, as a prerun option and as run-time
displays during a test run.
NOTE
When applicable, always define the excitation circuitry before displaying the
transducer signal.
•
Pre-Initialization —Before initialization, TCE can display transducer channels
before or after calibration. The eDAQ
lite
uses the user-defined sample rate and
digital filtering. The display types available before initialization are DVM, scope
plot and spectrum plot (i.e., Freq). Access all three types in the transducer setup
window. The DVM and scope plot displays are also accessible in the display
control section on page two of the transducer channel definition dialog box.
•
Prerun —The DVM, scope plot and spectrum plot display modes are available
as prerun options after initialization and before the first test run or between test
runs. To access the displays, select Transducer Checks from the Prerun Options
sub-menu of the Test Control menu.
•
Run Time —Run-time displays show the raw signals from input and computed
channels on a real-time basis providing verification that input and computed
channels are functioning properly. Run-time displays are only available while a
test is running. The available run-time display types are bar chart, strip chart,
digital readout, scope plot and spectrum plot. Access the display modes from
the Run-Time Displays option in the Test Control menu or toolbar.
NOTE
TCE stores the run-time display channel set and display mode in a RAM disk file.
When restarting a run-time display during a test, TCE starts the display in the last used
configuration.
The following table presents a summary of the displays in TCE, when they are
available and the maximum number of channels each supports.
