4.5.2 Storage of Individual Values using the SAMPLE or dAtA Sampling
Rate
If only individually selected values need to be saved, SAMPLE must
be selected as the StorE > rAtE sampling value. If memory mode
operation is then started, a single measured value is saved to per-
manent memory with time stamp when the DATA/MIN/MAX key is
pressed and held until two rapidly repeating acoustic signals are
generated.
If dAtA is selected as the StorE > rAtE sampling rate, and if mem-
ory mode operation is then started, measured values ascertained
with activated DATA function are automatically saved to perma-
nent memory with time stamp.
4.5.3 Rapid Momentary Value Acquisition for U DC and I DC
Rapid momentary value acquisition is only activated during mem-
ory mode operation in the U DC and I DC functions, and only after
selecting a sampling periods of 0.5, 1, 2, 5, 10, 20 or 50 ms: All
trigger and hysteresis functions are available, although the mo-
mentary value is acquired with a separate measuring circuit.
This allows for the recording of the waveshapes of low-frequency
signals with reduced resolution and accuracy (typically < 1% of the
measuring range under reference conditions, not specified).
Roughly 300,000 measured values can be saved in this mode.
Values of up to about 1.9 x Umax or Imax are recorded (with fixed
range, range-dependent fluctuations), and thus the range limits
can be exceeded by approximately 90%.
Note

The ZERO/REL function is not taken into consideration for
rapid momentary value acquisition!
