3.4.4

Excel

The easiest way to transfer data to Excel is to use the TC-08 software application.

If, however, you need to do something that is not possible using the TC-08 software,
you can write an Excel macro which calls

usbtc08.dll

to read in a set of data

values. The Excel Macro language is similar to Visual Basic.

The example

usbTC0832.XLS

reads in 20 values of the cold junction temperature

and channel 1 temperature, one per second, and assigns them to cells A1..B20.

3.4.5

LabVIEW

While it is possible to access all of the driver routines described earlier, it is easier to
use the special LabVIEW access routine.

To use this routine, copy

usbtc08.vi

from the

Examples

subdirectory to your

LabVIEW

user.lib

directory. You will then need

usb_tc08

sub-vi and an example

sub-vi which demonstrate how to use them. You can use one of these sub-vis for each
of the channels that you wish to measure. The sub-vi returns a temperature for
thermocouple types.

3.4.6

Visual Basic

The

Examples

directory contains the following files, created in Visual Basic 6:

usbtc0832.vbp
usbtc0832.bas
usbtc0832.Frm

usbtc0832.vbw

3.4.7

Agilent VEE

The example program

usb_tc08.vee

shows how to collect a block of data from the

USB TC-08. There are prototypes in

usb_tc08.vh.
