Max
The maximum digitized or calculated data point in the measurement zone of
the trace record. An overrange value in the trace record will qualify the
measurement readout with  ". If the trace is null, the measurement value
will show error".

where:
m = index of left most measurement zone sample
n = index of right most measurement zone sample
W(j) = sampled data point
The summation extends over the interval of time corresponding to one
period when Data Interval is set to one period, or the entire measurement
zone when Data Interval is set to the entire zone.

An overrange value in the trace record will qualify the measurement with  ",
and an underrange value in the trace record will qualify the measurement
with  ". If the trace record has both underrange and overrange values, the
measurement readout will be 0.0000 ?V". If the trace is null, the measure
ment value will show error".
Min
The minimum digitized or calculated data point in the measurement zone of
the trace record. An underrange value in the trace record will qualify the
measurement readout with  ". If the trace is null, the measurement value
will show error".
