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 Figure 3- 7 on page 59.
• 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.
