Dynamic Recording
N O T E
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.
1Press 
for more than 1 second to enter Dynamic Recording mode. The meter is now in continuous mode or
non- data hold (non- trigger) mode. “MAXMINAVG” and the present value of measurement are displayed. The multimeter will beep when a new maximum or minimum value is recorded.
2Press 
to cycle through maximum, minimum, average, and present readings. The MAX, MIN, AVG, and
MAXMINAVG indicators will appear, corresponding to the displayed readings.
3Press 
or 
for more than 1 second to exit Dynamic Recording mode.
•Press 
to restart the dynamic recording.
•The average value is the true average of all the measured values taken in the Dynamic Recording mode. If an overload is recorded, the
averaging function will stop and the average value becomes
"OL"(overload). 
is disabled in Dynamic Recording mode.
