Span: It is defined as the difference between the largest and smallest reading of the instrument.
If voltmeter scale is -V1 to V2, then the span is given by (V2 + V1)
Explanation:
The voltmeter scale is -5 V to 5 V
If voltmeter scale is -V1 to V2, then the span is given by (V2 + V1)
Now, span = 5 + 5 = 10 V
