11. Function menus
Scaling by means of a two-point adjustment
Sensors which are adjusted via the factor, e.g. force transducers and displace-
ment transducers, can also be adjusted online, as described previously in 11.3.
Simulate, select, and enter 1st setpoint 1 :
setpoint 1: -100.0
Adjust in
setpoint 1
by pressing :
<ADJ>
2. Simulate setpoint 2
For ALMEMO force transducers (see Manual 3.6.2)
Simulate the end value
Calibration resistance ON/OFF :
<S-ON> or <S-OFF>
Select and enter setpoint 2 :
2: 400.0
Two-point adjustment in setpoint 2 by pressing :
<ADJ>
Force transducer with calibration resistance are adjustable also in
the sensor display.
It is also possible to adjust the end value only - without changing the
zero-point.
11.5 Data logger functions
The 3 function menus
Data logger functions
can be used to acquire the measured values for
all measuring points either manually at certain
times or cyclically over a certain duration and to
record these either to the internal data memory
(type 3S/4S) or to an external memory card;
(see Manual 6.5). In the absence of all such
storage media these menus are not available.
The device status can be checked by means of the appropriate symbols
(see8.2) appearing in the top status bar of the menu.
11.5.1 Internal data memory
Data loggers ALMEMO 2590-3S and 2590-4S incorporate an internal 59-KB
EEPROM data memory, , sufficient for 7000 to 12000 measured values (de-
pending on the number of channels). In the event of a failure in the supply volt-
age the measured data is retained intact. The total memory capacity and the
free memory available are indicated in functions
Internal memory
and
Free
memory
. The EEPROM can be configured either as linear memory or ring
memory; (see 11.5.8.5, Manual 6.10.13.2). The basic information on saving
data in ALMEMO ® devices is provided in the Manual, Section 6.9.
PLEASE NOTE ! The first time the device is started only one sensor configuration
is saved to the internal memory; however, with effect from the next start this
can be supplemented by additional sensors. However, if other sensors are
connected the memory must be read out and then cleared before the next
recording session.
