Special Meas. Ranges ,Linearization ,Multi-Point Calibration - Ahlborn ALMEMO 2590-2 Operating Instructions Manual

12. Sensor programming
Advantage of device-internal channels
If several sensors are being used for the same application, they do not have to
be reprogrammed and can be freely exchanged without losing their function
channel assignment. However, if the whole application operates with just one
sensor, then programming on the sensor itself makes more sense.

12.11 Special meas. ranges ,Linearization ,Multi-point calibration

Thanks to the new ALMEMO
tional data (bigger EEPROM, code E4) the following tasks can now be per-
formed for the first time with great elegance :
1. Provision of special measuring ranges with internal characteristic (see 12.9)
2. Linearization of signals for voltage, current, resistance, or frequency - set by the user
3. Multi-point calibration of all sensors
The ALMEMO ® 2590 as standard can evaluate all appropriately programmed
connectors. On leaving the factory any device as of ALMEMO
special KL variant can, using the AMR-Control software, program measuring
signals as per a characteristic of up to 36 support values to the EEPROM on
the ALMEMO connector. During a measuring operation the measured values
®
between these points are interpolated on a linear basis. When correcting sen-
sors with linearization in their standard measuring range (e.g. with PT100 or
thermocouple sensors) initially the original characteristics are considered; only
then are the deviations interpolated on a linear basis and inserted.
If a channel with a characteristic is deactivated or programmed with a different
range, the characteristic can subsequently be reactivated by programming the
