Instrumentation Laboratory Exercise 19
2.5 Temperature display
Set up a Formula box (found in the Device menu) for calibration
allowing the subtraction of the “zero” reference voltage and
multiplication by the calibration factor as shown below. Display both
the raw voltage and the temperature converted to °C.
This shows how the temperature conversion can be performed in a
single formula box. To make the program run continuously we need
to add some program “flow control”.
First add a Start button from the Flow menu. Place it in the upper
left of the screen as shown in the figure above. Next add an Until
Break loop from the Flow menu (Flow > Repeat > Until Break). Place it
below the Start button and wire the Start button into the top of the
Until Break box.
The output of the Until Break loop (right side) should be wired into
the top of the MultiInstrument I/O box as shown above. This tells the
program to repeatedly read and display the temperature until halted
by a stop command.
NOTE
Notice that a single output can be run into many inputs (as with Vd feeding
both the formula and 1st AlphaNumeric boxes). You can not, however, feed
several outputs into a single input, as this would cause a conflict: which input
value should be used?
