Displayed measurements
When you make measurements, the instrument may perform operations on the measured values that
affect what you see on the display and the measurements that are stored in the buffer.
The operations that can affect the measurement display are:
•
Filtering
•
Relative offset
•
Math operations
•
Limit tests
If none of these operations is set, the value that is displayed on the front panel is the actual
measurement reading.
If any one of these operations is set, the value that is displayed is the measurement reading with
these operations applied. The operations are applied in the order shown above.
For example, if you made a measurement and had a relative offset and limit tests active, the
measured value would have the relative offset applied, then have limit test results applied.
For additional detail on the order of operations, see
(on page 4-25).
