Thanks to Arduino.cc. On December 31, my late Christmas present arrived at home. A Keithley DMM6500 - benchtop multimeter sponsored by distrelec. I won it at the ARDUINO / DISTRELEC: AUTOMATION & ROBOTICS CONTEST. This is how the year 2018 ended optimally. Contest and Sponsor Links https://www.arduino.cc/ https://www.distrelec.de/en
