Storage of Individual Values using the SAMPLE or dAtA Sampling Rate
If only manually 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.
triG – Trigger Conditions (parameters for memory mode operation)
The StorE > triG SEt = Sto-ou / Sto-in / OFF setting can be used
to specify how measured value recording is started and stopped:
• triG = off: Recording is started with Store > Start and ended
with Store > Stop.
• triG = sto-ou: Recording is started as soon as a measured value
occurs which is outside of the selected measuring limits, and is
stopped as soon as the measuring limits are once again com-
plied with, or the selected recording period has elapsed.
• triG = sto-in: Recording is started as soon as a measured value
occurs which is within a specified band, and is stopped as
soon as this is no longer the case, or after the maximum re-
cording period has elapsed.
The band is specified with the help of the L_triG lower limit and
the H_triG upper limit. Querying takes place in the event that
triG OFF is selected. Bandwidths are specified in digits and de-
fined by the measuring range limit, which, in the case of DC for
example, corresponds to 300,000 (–300,000 to +300,000). In
measuring functions with a small measuring range span (e.g.
V AC with 30,000 digits), it is not useful to set the trigger thresh-
old above this measuring range span. It’s thus advisable to perform
measurement with a fixed measuring range. Due to the fact that
rapid momentary value acquisition (see section 4.5.1) has a large
measuring range span, limit values of greater than 30,000 digits
can be selected.
Actual measurement is always executed using the sampling rate
selected in “Store > rAtE”.

tStorE – Recording Time (parameter for memory mode operation)
This parameter determines whether or not measured values will
be recorded for a limited time only. If recording time will be limited,
its duration can be entered in hours, minutes and seconds. “On”
means unlimited recording time.

After completion of the recording time t.StorE, the end of the stor-
age process is signalled by 2 short acoustic signals (as from firm-
ware version V1.14).
