Display functions (only available for devices with option -VO)
Currently measured values
During normal operation the display will show the temperature in [°C] or [°F].
Min/Max Value Memory
watch Min values (Lo): press ‘down‘(middle key) shortly once display changes between ‘Lo‘ and Min values
watch Max values (Hi): press ‘up‘(right key) shortly once display changes between ‘Hi‘ and Max values
restore current values: press ‘down‘ or ’up’ once again current values are displayed
clear Min-values: press ‘down’ for 2 seconds Min values are cleared. The display shows shortly ‘CLr‘.
clear Max-values: press ‘up’ for 2 seconds Max values are cleared. The display shows shortly ‘CLr‘.
After 10 seconds the currently measured values will be displayed again.

Segment test
The transducer performs a display test for 2 seconds after power up. After
that it will change to the display of the measuring.
Configuration of the device
The configuration of the device is done by means of the PC-software EbxKonfig or EASYBUS-Konfigurator.
The following parameters can be changed:
- Display unit of temperature measuring
- Adjusting of temperature display (offset and scale correction)
- Setting of the alarm function
The adjusting by means of offset and scale is intended to be used to compensate errors of the measurings.
It is recommended to keep the scale correction deactivated (“oFF”). The display value is given by following formula:
Display = measured value - offset
With a scale correction (just for calibration laboratories, etc) the formula changes:
Display = (measured value - offset) * ( 1 + scale adjustment/100)
