These digits make reference to the measuring range as fol-
lows: The positions of the digits in the pre-selected hyster-
esis correspond to the same positions within the measur-
ing range, but are counted starting at the left.
Example: A pre-selected hysteresis of 001000 for the
300.000 V measuring range means that only those mea-
surement values which deviate from the previous measure-
ment value by at least 001.000 V are stored.
All measurement values are stored to memory if hysteresis
is set to “all”. This may be required, for example, for real-
time analysis at a PC with simultaneous display at the
monitor.
➭ Enter the “SEt” menu mode (see chapter 21).

20.2 Trigger Functions
With the help of the trigger functions (except for events and
cont i), you can determine which measurement values are
stored to memory. In addition to this, storage to memory
can be started with various trigger types. A trigger event
occurs when high level is exceeded, or if low level is fallen
short of. Recording can take place either before or after the
trigger event. The duration of recording depends upon the
sampling rate, the hysteresis setting, available memory
capacity and the desired recording duration (durA).
Recording is activated with the shortcut key combination
ESC|FUNC and , or via the StorE menu (after all settings
have been completed).
In the following examples for the selection of parameters, V
represents trigger variables V, A, Ω, °C, μF, H z a n d d B. F u r-
thermore, the trigger function in represents in, out, St-ou
and St-in. An overview (flow chart) of the complete trigger
menu can be found on page 36.
Note!
☞
Changing the measuring function has no influence
on the trigger functions.
The following trigger parameters are not active if the
sampling rate is less than (faster than) 50 ms.
triG = OFF
If the triG function is set to OFF, measurement values can
be stored to memory independent of the measured quan-
tity (independent of parameters H.triG, L.triG, prEtr and
rEtriG). However, storage is dependent upon date and time
trigger parameters.
