Reading and changing the emissivity coefficient
The emissivity coefficient can be read by selecting the appropriate LCD
mode (with button 1).
The following modes are present:
show temperature.
The temperature is shown in degrees Celsius.
show sensor id.
The sensor id is shown in 4 digits.
This id is used for identifying the sensor.
show blank LCD screen.
In this mode the pt100 reading is reduced to a minimum. The radio
data transmission remains active.
show emissivity.
The leftmost digit shows ‘E’, the rightmost 3 digits show the actual pa-
rameter value from 0.10 to 1.00.
The LCD mode can be selected by pushing the left button shortly. A
next LCD mode will be selected each time the button is pushed shortly.
In order to set the emissivity value the following steps should be
performed:
Select the appropriate LCD mode: show emissivity.
Push the left button a long time (approx 5 seconds) until the ‘E’ digit
starts to blink.
Push shortly to increment the parameter value, the increment is in
steps of 0.05.
When you have selected the correct value, leave the device
untouched. It will jump to the show temperature mode after a few
seconds. At that point the emissivity is stored into the on board non-
volatile memory.
