By choosing Edit/Properties for instrument window, you will be able to set some of the following
Type: There are 2 types of instruments:
· Circle with classic round scale
· Non-graphic, with numeric value only
Modify instrument value: You can define coefficients to modify the instrument value after
calculation. It is useful if you need a calculation slightly different than the one included in SIGVIEW , for example if the unit you would like to use needs some scaling. You can define both
add (A) and multiply factors (B). The resulting instrument value will be calculated from the
originally calculated value by using the following expression: NewValue = A + B*OriginalValue.
Range: Value range for instrument scale
Units: Units for instrument value (Volt, meter, etc. )
Show signal marker: This option is available only for At..., Maximum, Minimum, Maximum
position and Minimum position instruments. If you turn it on, a marker will appear in the origin
signal, showing exact position for the value shown in instrument. You can define the content of
the marker by changing its text, or turning X/Y value display in the marker.
Critical value range: You can choose value range which represents the “red zone”. It will be
marked red on the instrument. By choosing Outside option in the radio box you will invert the
selection, i.e. all values outside that range will be marked red.
Play sound on critical value: SIGVIEW will play a single beep when the value is in a critical
Execute this application on critical value: You can enter complete path of an external
application to be executed if the value is in a critical range, i.e. if value of the instrument enters
“red-zone”. You can also define how often this application will be called. SIGVIEW will execute
defined application and pass current instrument value as a parameter to it. For example, if your
application is “C:\MyLogger.exe”, and value of 45.4432 causes alarm to goes off, SIGVIEW will
call “C:\MyLogger.exe 45.4432”. This function can also be used to simply log analysis values
outside SIGVIEW in some regular intervals.
As an example for the external application, SIGVIEW distribution includes “Logger.exe”
application. You can simply copy this file from SIGVIEW installation folder to some other folder
and enter its path to the instrument dialog. Logger.exe will log the values passed from SIGVIEW
in a TXT file with the name SIGVIEWLog_<current date>.txt in its working directory.
Another example for such external application is ULDigital.exe, also included with SIGVIEW
installation. This application can control digital outputs on devices compatible with Universal
Library from Measurement Computing(R), i.e. can turn external devices on or off. There are
following command line options: ULDigital.exe <duration in ms> <digital output>.
where <digital output> should corresponds with UniversalLibrary's FIRSTPORTA,
SECONDPORTA,... values. For example, on PMD devices these values are 10,14,18,... for
channels A0, A1, A2,... This application requires that Universal Library driver is installed.
