The coordinate system
A coordinate system makes it easy for the operator to access all configuration data as well as
measured and calculated values by means of a table. The coordinate system is based on 8
columns. Every value in this coordinate system can be reached by pressing the appropriate cursor
keys (arrows “
►
“ “
▼
“).
The display field
An alphanumeric single-line display with 12 characters enables data and measured values to be
indicated together with their abbreviated designations and units. The LCD has been designed in
such a manner that it is particularly suitable for battery-powered mode. At temperatures below -
20°C or exc60°C, the display may be impaired.
The system
A complete Flow Computer System has been developed on the surface of a few square centimetres
using the most advanced SMD technology with large-scale integrated components. Several device
functions, such as pulse counting, frequency measurement, keyboard controller and dispatcher
output, have been incorporated into a controller. Thanks to large-scale integrated components,
fewer chips are required and this also contributes to making the device reliable. The type of the
individual device essentially depends on the software used.
Program memory
The program memory of the base device is located in a flash memory on the main board, whereas
the data memory is located on an additional board.
Reset
In the case of a reset, the power supply is disrupted and the corrector is switched off during this
period of time. In this way, the program and the operating parameters will not be lost and also the
meter readings will be retained. A reset is made on the EC 21 / 24 by switching off not only the
battery but also a possibly available external power supply.
