Version information: Application 10,24,2007 DLL 3,22,2006,0 (requires driver version shown below - or newer) Device Driver 7,6,2004,0 You will need the VB runtime environment on your system to use the executable within the archive. You will have this already if you are a VB developer. If not a developer, you may have the runtime environment if you have installed another application that was built using Microsoft's Visual Basic software development tools. Please follow instructions within "ReadMe.txt" which can be found within the archive. Below is a copy of those instructions. =================================================== readme.txt for sample thermocouple application using Model 302 First, install driver and sample code from appropriate install disk if you haven't previously installed one of our devices. If the DLL from your installation has a newer version number, copy that DLL over top of the one in the sample application directory. Copy the USB_35b2.ini file to your Windows directory. Edit the USB_35b2.ini file that is in your windows directory as needed for ID number, rate, averaging and calibration parameters (gain and k-factor). Note that you can open the USB_35b2.ini file in the windows notepad by right-clicking your mouse on it and selecting notepad from the list that is shown. Connect digital outputs "A,B,C,D" back into the digital inputs, "1,2,3,4" respectivedly on the model 302. The digital outputs manage the channel switching within the 35b, while the digital inputs let the application know which digital input was last recogonized by the 35b, thus letting it know when all the channels have been switched and read. Run USB35b_X.exe Notes: The G factor and K factors within USB_35b2.ini will be slightly different for each individual thermocouple. The rate and averaging allow trading off speed and resolution. 50 Hz, averaging 4 should provide 0.01 deg C resolution. There are one or more sample log files in the sample application archive with names such as, "10-19-2007_15.51.44.txt". Such log files can be created by selecting the logfile checkbox on the application front panel and then when you start the temperature taking process, you'll be presented with a screen for a logfile name, or you can just use the default.
