The measured value is then no longer displayed, scanned, and output but the
programming is retained intact.

If the channel was previously deactivated, then it is now reactivated with all pro-
gramming values intact. However, if the channel is already active, then with
this key combination all its programming values are deleted (i.e. as per se-
lecting the measuring range).
7.7.1 Special meas. ranges, linearization,
multi-point calibration
Thanks to the new ALMEMO special connectors with extra memory for additio-
nal data (larger EEPROM, code E4) the following tasks can now for the first ti-
me be elegantly performed :
1. Provision of special measuring ranges with internal characteristic (s. 10.3.9)
2. Linearization of signals for voltage, current, resistance, or frequency set by
the user
3. Multi-point calibration of all sensors
The ALMEMO 2890-9 can as standard evaluate all appropriately programmed
connectors. With the special KL variant it is also possible to convert measuring
signals into appropriate display values in line with a characteristic of up t 35
support values. These support points are programmed to the EEPROM in the
ALMEMO connector using the AMR-Control software. During a measuring ope-
ration the measured values are interpolated between these on a linear basis.
When correcting non-linear sensors (e.g. with Pt100 or thermocouple sensors)
initially the original characteristics are considered; then only the deviations are
interpolated on a linear basis and inserted.
If a channel with a characteristic is deactivated or programmed with a different
range, the characteristic is subsequently reactivated by programming the spe-
cial range
