Difference between a Memory HiCorder’s maximum rated voltage to earth and its maximum input voltage
QIn the specifications for a Memory HiCorder input unit, a maximum rated voltage to earth as well as a maximum input voltage are listed. What is the difference between these two characteristics?
A
The maximum rated voltage to earth is the upper limit voltage that can be applied between input channel and the instrument’s enclosure or between input channels without damaging the instrument. By contrast, the maximum rated input voltage is the upper limit voltage that can be applied between input terminals without damaging the instrument.
