Displaying the outer bins
Two additional bins independent of the number specified are always included
with the histogram. The bins contain readings less than the lower range value and
readings greater than the upper range value (Figure 6-5 and Figure 6-6). A
number of readings greater than expected in either bin may indicate a drift in the
measured quantity.
The bins are viewed using the Outer Bins softkey, and the bin indices (Figure 6-6)
account for the bins whether they are displayed or not.
Bin representation
The softkey:
corresponds to the bin with the largest number of entries and is expressed as an
exact count (Count), or the bin’s percentage (%) of the total reading count. This
setting is only available from the front panel.
Lower and upper ranges
The lower and upper ranges of the histogram are specified directly with the
commands:
CALCulate2:TRANsform:HISTogram:RANGe:LOWer
{<value>|MINimum|MAXimum|DEFault}
CALCulate2:TRANsform:HISTogram:RANGe:LOWer?
[{MINimum|MAXimum|DEFault} (query form)
CALCulate2:TRANsform:HISTogram:RANGe:UPPer
{<value>|MINimum|MAXimum|DEFault}
CALCulate2:TRANsform:HISTogram:RANGe:UPPer?
[{MINimum|MAXimum|DEFault}] (query form)
