Math Operations
Dynamic recording
The dynamic recording mode can be used to detect intermittent turn-on or turn-off
voltage or current surges, and to verify measurement performance without your
supervision. While the readings are being recorded, you may perform other tasks.
The average reading is useful for smoothing out unstable inputs, estimating the
percentage of time a circuit is operated, and verifying circuit performance.
The operating procedure is described below:
1
Press
MAX • MIN
for more than 1 second to enter the dynamic recording
mode. The instrument is now in continuous mode (non-data hold mode), and
the instrument will display the
MAX AVG MIN
annunciator and the present
(instantaneous) reading.
– The instrument will constantly calculate and update the average measured
value in the memory.
– Whenever a new maximum or minimum value is recorded, the instrument
will beep once.
2
Press
MAX • MIN
to cycle through the maximum, minimum, average and
present readings. The
MAX
,
MIN
,
AVG
, or
MAX AVG MIN
annunciator will
appear to indicate which value is being displayed. See
– While you are viewing the recorded maximum, minimum, or average readings,
the instrument will continue to measure or calculate and update these values.
3
Press
MAX • MIN
for more than 1 second to exit the dynamic recording mode.
NOTE
– If an overload condition occurs, the averaging function will stop. The
recorded average value becomes
OL
(overload).
– In dynamic recording, the auto power off feature will be disabled. This is
indicated by the absence of the
annunciator on the display.
– When performing dynamic recording in autorange, the maximum, minimum,
and average readings may be recorded in different ranges.
– The recording interval in manual range is approximately 0.067 seconds.
– The average value is the true average of all measured values taken since the
recording mode was activated.
