Setting Hysteresis
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 selected digit in the specified hysteresis value corresponds
to the same position within the measuring range, although count-
ing is started at the left.
Example: A specified hysteresis of 00100 for the 300.00 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
measuring range, it’s advisable to use the function with a
fixed measuring range only.
This parameter cannot be set during memory mode operation.
➭ Press the MENU key.
➭ Press the General Setup softkey.
➭ Select the Memory menu with the
 scroll keys.
➭ Switch to the submenu with the help of the
 scroll key.
➭ Select the Hysteresis parameter with the help of the  scroll
keys.
➭ Acknowledge the selected parameter by pressing the OK key.
➭ If the parameter is set to off, activate hysteresis by a pressing
the
 scroll key.
➭ Then select the desired entry position within the parameter
using the   scroll keys and change the respective value
(00000 digits) with the  scroll keys.
➭ Acknowledge your change with the OK key. The entry cursor
once again marks the entire parameter line.

➭ Hysteresis is deactivated again by selecting the first digit or
the leading zero of the displayed hysteresis value, pressing the

Trigger Mode Operation
The Off, Outside Limits and Inside Limits settings
can be used to specify how measured value recording is started
and stopped:
• Trigger = Off: Storage is started with Recording > Start and ended
with Recording > Stop.
• Trigger = Outside Limits: Recording is started as soon as a mea-
sured value occurs which is outside of the selected measuring
limits, and is stopped as soon as this is no longer the case, or
after selected Record Time is exceeded.
• Trigger = Inside Limits: Recording is started as soon as a mea-
sured value occurs which is within a specified band, and is
stopped as soon as this is no longer the case, or after maxi-
mum Record Time has elapsed.
The band is specified with the help of the lower trigger limit (Trigger
Low Limit) and the upper trigger limit (Trigger High Limit). The limits
are entered in digits and are defined by the upper range limit. In
the case of DC, for example, this is 30.000 (–30.000 to +30.000).
For measuring functions with a minimal measuring-range span,
for example R
LO
or m/4 with 3000 digits, setting the trigger
threshold above this measuring range limit does not make sense.
It’s thus advisable to perform measurement with a fixed measur-
ing range.
Actual measurement is always executed using the selected sam-
pling rate.
Note
Measurements performed close to the trigger level may
result in an incorrect display. If this is the case, select a
smaller voltage measuring range. In the case of mea-
sured values which are much higher than the expected
results, the input signal may be distorted. Perform mea-
surement with activated 1 kHz low-pass filter in this case.
