PROBLEM
POTENTIAL CAUSE
SOLUTION
My instrument does not appear in the
Choose Instrument / Device ID menu.
The instrument is not connected to the
computer properly or the power is not on.
•
Check the power cables to make
sure they are attached properly and
securely, and the rear power switch is
turned on.
•
Check USB cable or Ethernet cable
and network settings.
The changes I have made on the VI are
not appearing on my instrument.
The VI is not communicating with the
instrument.
Make sure that the "Run" or "START"
button on the VI is pressed to have
remote changes implemented.
I'm getting a LabVIEW timeout error,
device ID error, or an incompatible
instrument error.
Communication with the instrument has
not been established or has been lost.
Restart the application and re-select
the proper instrument in the Choose
Instrument / Device ID menu.
I try to run the Runtime Environment file
and "
This application can't run on your
PC
" shows up
The NI file downloaded is corrupt.
Download the file again.
I don't know what version of the file I'm
running
On the executable file, right click then
choose
Properties
. The version number
is on the
Details
tab .
Context Help is not displaying.
Context Help is disabled.
Under the Help menu of the NI Runtime
Engine, choose
Show Context Help
. Or
press Ctrl+H.
I try to change the temperature in the TC
LAB VI, but the VI resets the value to a
different temperature.
A Temperature Scan is in progress.
Either wait for the temperature scan to
finish, or abort the temperature scan to
enable immediate temperature setpoint
adjustment.
When I click "Get Errors" in the TC LAB
VI, the button lights up, but no errors
appear.
Either an IntelliTune scan or a
Temperature Scan is in progress.
If the VI is currently running an IntelliTune
or a Temperature scan, the VI waits for
the scan to complete prior to checking
for errors. If you wish to see the errors
immediately, abort the scan that is
running.
I can't press the
START
button or the
STOP
button. They are "grayed out."
The VI has stopped/disconnected from
the instrument.
Press the
Run
button (upper left hand
corner) and then the
START
button.
You may need to select your instrument
beforehand.
If the application has stopped
ungracefully, restart the VI.
I downloaded the Runtime Engine and
installed it, but the error saying I need it is
still showing.
Installed 32 bit instead of 64 bit (or the
reverse).
NI Runtime Engine is specific to the
computer on which you are installing.
In Control Panel - System determine if
you have 32 or 64 bit system. Install the
corresponding NI Runtime Engine.
During temperature scan, after each step,
it seems to miss a datapoint.
When setpoint changes, P, I, & D
coefficients are recalculated. There is a
brief time where Actual Temperature is not
available. Accurate date is still recorded.
Try STABLE scanning.
