10. Measuring operations
10.3 Measured value memory
On the ALMEMO
®
2450-1 any measured
value can be saved. To save the measured
value press key :
MEM
.
The value most recently saved then appears
in the function field preceded by the symbol
´M´. To return to the channel display press
key :
M

.
10.4 Relative measuring
One very useful function is to zero the mea-
sured value at certain locations or at certain
times as a reference value in order then to
observe only the subsequent deviations. This
function is independent of the locking status
and does not modify the programming param-
eters in the connector.
To zero-set the measured value press key :
CLR
.
To display relative measuring press arrow :
REL
.
To return to normal measured value press and hold down key :
CLR
.
Setting to zero automatically deletes the maximum and minimum val-
ues for this channel. The
MAX
,
MIN
, and
MEM
functions are thus also
available for relative measurement.
11. OUTPUTS
The following interfaces corresponding accessories or options either are nec-
essary. (see 14.2)
11.1 Interfaces
The ALMEMO
®
2450-1 version with the interface can not only be completely
programmed via the computer thus enabling the user to read out all acquired
data (see Manual Ch 6) but also be networked together very easily thus en-
abling the user to centrally acquire and record measured values from several
measuring instruments - even if these are located far apart (see Manual 5.3) .
The data cables required for this purpose (see Manual 5.2) are plugged into
socket A1. The baud rate for all data cables is is programmed on leaving the
factory to 9600 baud; this setting should not be altered.
As an alternative option I is available with an integrated
RS485 interface
. Via
6-pin ALMEMO
®
clamp connector ZA1000-FSV these devices can be con-
nected directly either to network distributor ZA5099-NVL or to bus driver
