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 99,999
seconds. When this maximum time is exceeded, “OL” is shown on the display.
1 Press for more than 1 second to enter the Dynamic Recording mode.
The multimeter is now in continuous mode or non-data hold (non-trigger)
mode. and the present measurement value is displayed. The
multimeter emits a sound when a new maximum or minimum value is
recorded.
2 Press to cycle through maximum ( ), minimum
( ), average ( ), and present readings ( ).
3 Press or for more than 1 second to exit Dynamic Recording mode.
– Press to restart dynamic recording.
– The average value is the true average of all 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). Auto Power Off
is disabled in Dynamic Recording mode.
