Measured Value
A continuous presentation of measuring data from the selected measuring
point is provided and also includes automatic zero point correction and, if
required, a correction of the measured value. A sensor breakage condition is,
with most sensors, automatically detected (exception: connectors with shunts,
dividers or additional electronics).
Measuring Functions
Some sensors require special meas. functions to achieve an optimal
acquisition of meas. data. The cold junction compensation is available for
thermocouples and a temperature compensation for dynamic pressure and pH
and conductivity probes. With infrared sensors the parameters zero point and
slope correction are used for background temperature and emissivity factor.
Maximum and Minimum Value
Each measurement involves an acquisition and storing of the maximum and
minimum value. These values can be displayed, printed or cleared.
Storage for Measured Values
The measured value can be frozen in the display by the push of a button.
Differential Measurement
By setting the measured value to zero it is possible to perform differential
measurements related to a reference value or to correct sensor errors.
External Sensor Programming
All sensor programming is supported when they have been programmed in the
factory or by using other ALMEMO
®
devices.
Dimension
The 2-digit dimension can be altered for each measuring channel so that the
display will always indicate the correct dimension, for example when a
transmitter is connected.
Correction of Measured Values
For correcting meas. values a zero point and slope (gain) correction can be
applied to the meas. value of a meas. channel. As a result, sensors can be
interchanged that usually, at first, require an adjustment (expansion, force, pH).
Scaling
The base value and the factor allow for a further scaling of the corrected
measured value of each measuring channel for zero point and slope (gain).
The decimal point position can be set by the exponent.
Analogue Output and Scaling
By means of analogue start and analogue end the indicated meas. value can
be scaled so that the resulting meas. range covers the full analogue output
range (2V, 10V or 20mA).
