Single Ended Input Measuring Device

A single ended measuring device has the negative input internally connected to
the devices ground pin.

Note: The Ground voltage must not be more than 4.5 volts below Battery–.

Note: If the Ground voltage is greater than the Battery – voltage then the PLM
output voltage swing will be reduced. (See the specifications for details)
