11. Programming With Programming-Menus
11.4.4 Analog Output Start and End
In most cases the analog output of measured values to the analog output mod-
ules (see manual 5) or the display as bar or line chart must be scaled to a
specified sub-range. For this, it is just necessary to specify the start and end
value of the display range required by you. This range is then mapped to the
analog range 2V, 10V, 20mA or, for the display, to 100 dots.
Programming the
analog output start
:
6 Analog start: 0.0°C
Programming the
analog output end
:
6 Analog end: 100.0°C
These two parameters, analog output start and analog output end, are also
stored in the EEPROM of the sensor and can, therefore, be individually pro-
grammed for each channel, i.e. during a manual switch through the channels
an individual scaling is available for each measuring variable.
The flag for switching over from 0-20mA to 4-20mA can be programmed
through the element flags (s. 11.4.8).
There is the assistant menu
Analog output
(s. 11.6.3) to programm all pa-
rameters of an analog output.
11.4.5 Output Function
If not the real measured value to the measuring point Mxx but only the Max,
Min, Average or Alarm value is required, then this function can be programmed
as output function (see manual 6.10.4). As a result, only the corresponding
function value will be considered for storing and analog or digital output. For
control of the changed output function the symbol below is displayed next to
the measured value (s. 9.3).
Examples:
1. If meas. values are averaged over the cycle only the average value is rele-
vant as output value, but not the last measured value. This way, memory
space can be saved in a data logger.
2. The analog measured value of the dew sensor FH A946-1 has no meaning.
If the limit value Max is set to approximately 0.5V, and the measuring func-
tion ´Alarm Value´ is programmed only the relevant values 0.0% for dry and
100.0% for ´dew´ will be displayed.
