Modern precision multimeter measurements - putting theory to the test. (55.34 KB)

In a controlled experiment we asked five laboratory personnel to perform some basic measurements using the same precision digital multimeter the results yield an unusually wide spread of readings – why? Is the operator or the instrument to blame or were the results within an acceptable measurement uncertainty! Modern precision multimeters have numerous measurement modes to cater for a diverse range of applications, but which mode is right. This paper unravels the confusion over choice of instrument operating modes and promotes best measurement practices to maintain consistent and repeatable measurements.
