I hosted a webinar on November 3, 2023 on
"Preload measurement circuit for bolt-clamped ultrasonic Langevin transducers"

Summary
In this webinar, I show how to modify a multimeter to create a Giga-Ohm input impedance for measuring voltage. Why do this? To create a super stable voltage measurement for measuring transducer preload voltage.
***Announcement***
My next webinar will be on Friday, November 10, 2023 at 11AM EST. I will cover
"Using an Arduino/microcontroller to measure transducer preload voltage and convert it into MPA/stress”
