Minimum Input Span
The minimum input span is the minimum difference between input 1 and input 2
signals required to complete the calibration or scaling of the meter. The minimum
span is 0.10 mA.
If the minimum span is not maintained, the meter reverts to input 2, allowing the
appropriate input signals to be applied.
