I have used my Fluke ScopeMeter for all kinds of things but it really made me shine when I used it to install a steered laser marking system used to mark pharmaceutical products. The printer marks when the machine has come to a stop, so I connected one channel of my scope to the drive motor signal and the other to the printer trigger signal. I was then able to see when the printer was triggered and when the motor stopped. By using the cursor measurements, I was able to set the printer's trigger delay time to allow for minimum idle time and maximum print time, guaranteeing that the printer will always have enough time to print more characters than will ever be required for this application.
