10. Measured data acquisition
- Ring memory mode is not supported.
- Sleep mode
- Data can be evaluated using any reader on site or anywhere else.
- Very fast data transfer via the reader
- Data recording and output in table format only
- On the ALMEMO
®
device itself only the last file can be read.
- Selective data output according to date and time-of-day or by number
code is not supported
The memory connector with the memory card can be connected at socket A2;
it will be recognized automatically. If at the start of any measuring operation an
external memory has been connected, it will be used. In the course of a mea-
suring operation the external memory must not be unplugged; all temporarily
buffered measured values would be lost.
Before starting any measuring operation you can enter an 8-character file
name. (see Ch. 11) In the absence of a user-defined file name, the default 'AL-
MEMO.001' or the name most recently used will be suggested automatically.
So long as the connector configuration is not altered, any number of measuring
operations can be saved - either manually or cyclically, also with number
codes, all in the same file.
If, however, the
connector configuration
has been changed since the last
measuring operation, a new file will be created; and, if no new file name has
been programmed, the index in the file name extension will automatically be in-
cremented by 1, e.g. '
ALMEMO.002
'. Similarly, if the file name now entered al-
ready exists, a new file will be created with the same file name prefix but with a
new index.
11. SPECIAL MEASURED QUANTITIES, LINEARIZATION,
MULTI-POINT CALIBRATION
Thanks to the new ALMEMO
®
V6 connectors with extra memory for additional
data (bigger EEPROM, code E4) the following tasks can now be performed
with a certain elegance.
1. Provision of special measuring quantities with internal characteristic
2. User-defined linearization of linear signals for voltage, current, resistance,
or frequency
3. Multi-point calibration of all sensors
4. Serial number and calibration data management in the sensor
The ALMEMO
®
809 can as standard evaluate all appropriately programmed
special connectors. With option KL it is also possible to convert measuring si-
gnals into equivalent display values based on a characteristic of up to 35 inter-
polated values. These control points can be programmed and saved in the EE-
PROM in the ALMEMO
®
connector using the ALMEMO
®
Control software
(menu <Measuring points> list <Program measuring point>, <Measuring
point>, multi-point calibration / special linearization). During a measuring opera-
