Automotive fuse tester.  An automotive fuse manufacture needed an end of line test to test fuses they were manufacturing.  The system needed to measure the resistance of each fuse and compare it to an entered value.  The system then needed to determine if the fuse was acceptable or faulty and save the results for the test.  The software needed to be easy to use and interface with different hardware components.

 

 

 

Data logger and controller using CompactDAQ and LabVIEW.  An automotive test lab needed a general data logger and digital controller to perform tests on their products.   The system needed to monitor thermocouples, accelerometers, voltages, and a rotary encoder.  Low and high limits needed to be assigned to the analog inputs, and if the measured value exceeded the limits the software would report a fault.  The software had to also control digital outputs.   The software needed to turn on and off digital outputs for a user specified time in a user specified sequence.  Each digital output needed to controlled independently.  

 

The customer wanted to use off the shelf data acquisition hardware to reduce costs and standardize the hardware in the lab.  The hardware also needed to be able to measure different signal types i.e. thermocouples, thermocouples, and voltages.

 

The software needed to be able to add additional features to accommodate changing test requirements.

 

 

Automotive Console Cycle Tester using CAN.  An independent testing lab needed to test an automotive console.  An automotive console is a device in an automobile that controls the options in a car.  For example the heating and air conditioning and the radio.  The customer wanted to test up to 10 consoles simultaneously.  The consoles also could be different models of consoles.  They needed the software to send and receive CAN messages to the console and do cycle testing.   Cycle testing is a type of test that exercises the part for a defined number of cycles.  For example sending a message to turn the radio on and off.  The test also needed to allow the user to use a control on the software user interface and send that command via CAN to the device under test.
