Function Range of the ALMEMO 2890-8
perature and emissivity factor.
Max and Min Value
Each measurement involves an acquisition and storage of the Max value and
the Min value including the time and date. The values can be displayed, printed
or cleared.
Average Value
Measured values can be expressed as a sliding average obtained by continu-
ous automatic smoothing or averaged over a particular period or cycle or over
a series of individual measuring operations.
5.1.3 Process flow control
A continuous measuring point scan with a time-based process flow control for
the output of measuring valures is required to register the measuring data of all
connected sensors. For this purpose, an output cycle is available and, if fast
processing is required, the conversation rate is available. The measurement
can be started and stopped by using the keyboard, the interface, an external
trigger signal, the real time clock or an exceeding of limit values.
Time and Date
The real time clock with data function or the pure measuring time are used for
an accurate recording of any measurement. Start and end time/date can be
programmed in order to start or stop a measurement.
Cycle
The Cycle is programmable between 1 s and 59 h, 59 min and 59 s and pro-
vides a cyclic output of measured values to the interfaces or memories and
also provides a cyclic averaging.
Print Cycle Factor
If necessary, the print cycle factor allows for limiting the data output of particu-
lar channels so that an excessice data flow can be limited, especially during
data storage.
Average Value over Measuring Point Scans
The measured values resulting from scanning measuring junctions can be av-
eraged as desired either over the total measuring time or over the cycle time.
Function channels are available for a cyclic output and storage of these aver-
age values.
Conversion Rate
With the ALMEMO
®
2890-9 all measuring points can be continuously scanned
with the conversion rate (2.5;10 or 50 M/s). To realize a high recording speed it
is possible to store all measured values in the memory and/or to perform an
output via the interface.
Data Memory
During the cycle, all measured values can be manually or automatically stored
in an EEPROM. The memory capacity is, as standard, 512 Kilobyte, which al-
