Topics covered or mentioned in this video: Calibration, precision references, standards, ISO9000, NIST (national institute of standards and technology), traceability, uncertainty, repeatability. Calibration certification, accuracy, resolution, absolution accuracy, ppm (parts per million). I received some voltage references I will be testing and learning more about their performance. The precision voltage references I have or will be receiving: AD581KH 10V AD586JN 5V ADR130 V-Ref Programmable 0.5V/1V 4mA ISL21009BFB850Z V-Ref Prec,5.0V,7mA ISL21009BFB812Z V-Ref Prec,1.25V,7mA REF5050AID 5.0V Voltage Reference REF102 V-Ref Precision 10V 10mA Precision Metal Film Resistors RC Series 0.1% tolerance, Temperature Coefficient 15ppm/°C: 1.24kΩ 255kΩ 46.4kΩ 124Ω 255Ω Multimeters used: Fluke 287, Metrix MTX3282, Brymen TBM867 / BM867, Fluke 287, ISO-TECH IDM207 Fluke 8846A bench multimeter 6.5 digit (1 000 000 count) accuracy of 0.0024% 8.5 digit HP 3458A DMM - accuracy of 0.0008% HP 3478A 5.5 digit What is traceability? What is uncertainty? What is a standard?
