10. OPTION KL
Special measuring ranges
linearization, multi-point calibration,
calibration data management
Thanks to the new ALMEMO ® special connectors with extra memory for addi-
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
2. User-defined linearization of signals for voltage, current, resistance, or fre-
quency
3. Multi-point calibration of all sensors
4. Serial number and calibration data management in the sensor
The ALMEMO ® 8590-9 can as standard evaluate all appropriately programmed
special connectors. With option KL you can also convert measuring signals into
equivalent display values based on a characteristic of up to 35 support points.
These support points can be programmed to the EEPROM in the ALMEMO
®
connector using the AMR-Control software (menu <Measuring points> list <Pro-
gram measuring point>, <Measuring point>, multi-point calibration / special lin-
earization). During a measuring operation the measured values between these
points are interpolated 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 can subsequently be reactivated by restoring the spe-
cial range using command ´
B99
´.
Other information that can be entered in the extended connector includes the
order number, the serial number, the date of the next calibration, and the cali-
bration interval. In internetworked systems this permits automatic monitoring of
the calibration intervals; (for commands see Ch 11).
