Q:
Please share with us any “non-standard” applications that data acquisition systems and instruments have been used for.

Answers:
In our application, we have designed our own data acquisition system to control the output of a rectifier (130-200 kilo ampere) output. Our input is the real-time 100 ampere pulse.
~Juanito M, Systems Project Leader, Dubai, UAE
My standard application the combustion engine measuring, pressure, needle lift, air flow intake manifold, but my "non-standard" was the tubeless tire development.
~Géza M, Engineering Consultant, Budapest, Hungary
As a GPS logger on holiday. Yes, I used my motorsport data acquisition system to trace where I drove on my holidays.
~Michael D, Data engineer, Amersfoort, Netherlands
What would be considered "non-standard" when acquiring any type of data? You may mean non-traditional applications.

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of data acquisition systems and instruments?
14 answers
Answers:
* Numerous issues with software. * Sampling rate vs Hz as in (9). * In one radio telemetry application the transmitted timebase was not accurate - not helpful for vibration measurement. * Software can have obscure lower level menu settings.
~Rod M., Engineering Consultant, Auckland, New zealand
Anything that is purchased without a good idea of the cost throughout the life of the system. Having to buy something after 4-5 years service because of obsolescense is very expensive and disastrous especially if one cannot access data.
~Gary G, Business Development, Wellington, OH
Voltage, Amps, bang ?? ALWAYS use one of those little boxes that tell you how much amps and volts are coming out of that little wire. just because it looks like a 5volt analogue sensor ...
~Michael D, Data engineer, Amersfoort, Netherlands
Yes, inadequate calibration and bookkeeping. It costs lots of money as the receiver will not pay the merchandise if calibration is not done properly and in time.
~Paul D, Engineer, Duketown, Netherlands
If Interfaces are not properly understood & designed & interconnect the system with devices, it may end up with serious consequences.
~Uttiramerur PADMANABHAN, Consultant, Bangalore;, India
