7.1.2 Memory for Peak Values
From the acquired measured values of each measuring point the highest and
lowest value is determined and stored. For indicating the peak values the
function MAX VALUE or MIN VALUE must be selected with the key
MEASURE
and the desired channel must be set.

The peak values are also cleared if a change of the measuring range (see 6.2)
is carried out.
7.1.3 Setting Measured Value to Zero, Zero Point Correction
Setting the Measured Value to Zero
The user can zero the measured value at certain locations or at certain times in
order to check the deviation from this reference value. The indicated measured
value is, by the following key combination, stored as base value and, as a
result, set to zero.

Please note that this function is only available if the locking code is
set below 5 (see 6.7).
If the function ´
BA
´ is activated, the new base value is stored in the
EEPROM of the connector (see 6.6). If not, the original value is
inserted again when the instrument is switched off and on.
The arrow
CORR
. appears in the display as long as the deviation
from the base value is indicated, but not the actual measured
value.
The base value must be cleared in order to obtain the actual measured value
(see 6.6). If the function BASE ´
BA
´ is not activated, switching off the device is
sufficient (see above). However, if the function is available it has to be selected
by using the key
FUNCTION
and the base value has to be cleared by using the
keys
