Dynamic Recording
The Dynamic Recording mode can be used to detect
intermittent turn- on or turn- off voltage, current surges or to
verify measurement performance without you being present
during the process. While the readings are being recorded,
you are free to perform other tasks.
The average reading is useful for smoothing out unstable
inputs, estimating the percentage of time a circuit is
operating and verifying circuit performance. The elapsed
time is shown on the secondary display. The maximum time
is 99999 seconds. When this maximum time is exceeded
“OL” is shown on the display.

value is recorded.

average, and present readings. The MAX, MIN, AVG, and
MAXMINAVG indicators light up, corresponding to the
displayed readings.
