DYNAMIC RECORDING
The dynamic recording mode can be used to catch intermittent and turn on or turn off
surges, verify performance, measure while you are away, or take readings while you are
operating the equipment under test and can not watch the meter. Refer to Figure 7.
The average reading is useful for smoothing out unstable or changing inputs, estimating
the percent of time a circuit is operational, or verifying circuit performance.
The operational procedures are described below:
1 ) Press and hold the "MAX * MIN"pushbutton to toggle recording mode on or off. The
dynamic recording mode is indicated when the MAX AVG MIN annunciator turns on.
The present value is stored to memories of maximum, minimum and average.
2) Press this button momentarily to cycle through maximum, minimum,average and
present readings. The MAX, MIN, AVG annunciator turns on respectively
to indicate what value is being displayed. See Figure 3)
3) The beeper sounds when a new maximum or minimum value is recorded.
4) If an overload is recorded the averaging function is stopped. An average
value becomes " OL"(overload).
5) In dynamic recording, the auto power off feature is disabled and the " Off" turns off.
6) By selecting dynamic recording in the auto range, the meter will record the value
of MAX, MIN or AVG for different ranges.
7) The record speed of dynamic recording is about 100 milli-seconds (0.1 second).
8) The average value is the true average of all measured values taken since the
recording mode was entered.
