9.10.4 Analog Output Start and End
In most cases the analog output of measured values to the analog output
modules (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:
AnalogStart: 0.0°C
Programming the analog output end:
AnalogEnd: 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
programmed 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 (see 9.10.8).
9.10.5 Output Function
If not the real measured value 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 (see 5.3).
Example:
1. If meas. values are averaged over the print cycle by means of the meas.
cycle, only the average value is relevant 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
function ´Alarm Value´ is programmed only the relevant values 0.0% for dry
and 100.0% for ´dew´ will be displayed.
