Device and Measuring Parameters
6.5 StorE Menu – Parameter for Memory Mode Operation
HYSt – Hysteresis (parameter for memory mode operation)
The hysteresis setting allows for efficient use of memory space.
During memory mode operation, new measured data are only
saved if they deviate from the previously stored value by an
amount which exceeds the selected hysteresis value.
Hysteresis can be selected in steps from 1 to 10,000 digits. These
digits are related to the measuring range as follows: The position
of the set digit in the specified hysteresis value corresponds to the
same position within the measuring range, although counting is
started at the left.
Example: A specified hysteresis of 00100 for the 600.00 V mea-
suring range means that only those measured values which devi-
ate from the last measured value by more than 001.00 V are
saved to memory.
Note

Due to the fact that the value is specified in digits (highest
place all the way to the left), and thus depends on the mea-
suring range, it’s advisable to use the function with a fixed
measuring range only.

rAtE – Set Transmission and Storage Rate
The sampling rate specifies the time interval after which the
respective measured value is transmitted to the interface, or to
measured value memory.
Any one of the following sampling rates can be selected:
[mm:ss.
0 ] 00:00.1, 00:00.2, 00:00.5, 00:01.0, 00:02.0, 00:05.0
[h:mm:ss.
0 ] (h = hours, m = minutes, s = sec., 0 = tenths of a sec. )
0: 00:10 , 0: 00:20 , 0: 00:30 , 0: 00:40 , 0: 00:50 , 0: 01:00 , 0: 02:00 , 0: 05:00 ,

The last selected value is retained, even after switching the instru-
ment off.
If the selected sampling rate is too short for the measuring function,
the smallest valid sampling rate is used automatically.
If a sampling rate is selected which is greater than auto power off time
(see APoFF parameter on page 51), the instrument is switched off
automatically after auto power off time has elapsed, and back on
again roughly 10 seconds before the next measuring point.
