7.3 Memory for Momentary Values
If a measured value, e.g. for easier evaluation, is frozen at a certain point in
time, the key
HOLD
must be operated. The hold mode is indicated in the display
by an arrow under the ´
HOLD
´ symbol.
Function HOLD
Freezing of measured value with key:
HOLD
HOLD
MIN
MAX
CORR
M
DIM
With each additional operation of the key
HOLD
, the momentary measured
value will be taken over and displayed.
To return to a continuous display of the current measured value, the key
CLEAR
or
MEAS.
must be pressed. The arrow ´
HOLD
´ will turn off.
7.4 Differential Meas. and Correction of Meas. Values
In the function
MEASUREMENT
the key
CLEAR
can be used to set the current
measured value to zero, i.e. the current measured value will be stored as
reference value and the difference to this reference value will be displayed. To
indicate the differential mode the arrow ´
CORR
´ will flash in the display.
Set measured value to zero with key:
LÖSCHEN
HOLD
MIN
MAX
CORR
M
DIM
When a zero setting is performed, the max and min values of this channel will
be automatically cleared.
If a base value has been programmed (see man. 6.3.11) the
measured value will not be zero but the negative base value after
the adjustment.
For example, if the temperature is set to zero at a certain point, the differences
to the reference point can be read at any point. The MAX, MIN and HOLD
functions are also available when difference measurements are performed.
The reference value will only be cleared when the key
MEAS.
is operated again
in the function MEASUREMENT or when the instrument is being switched off.
In this case the max and min values will also be cleared and the arrow ´
CORR
´
will stop flashing.
