tyPE MAIN INPUT TYPE OF PROBE I.MAIN R W
The parameter shows and sets the sensor type of the main input.
The functions for calibrating Custom sensors are on the US.CAL menu.
When a 4...20 mA input is used and the current is less than 2 mA, an Err message is generated and the relay state speci-
fied with the FAUL.T parameters is activated.
The table shows the scale limits for each sensor type or input based on the set number of decimals.

Nota: the infrared temperature sensor has an output in voltage for direct connection to the input terminals of the temperature con-
troller. An external thermometer is needed in order to correct the sensor error.
After identifying the work temperature range (for example, 140 – 260°C), set an SP near the minimum scale value, and after rea-
ching it make a note of value A1 indicated by the instrument and of value A2 indicated by the external thermometer. Set an SP near
the maximum scale value, and after reaching it make a note of value B1 indicated by the instrument and of value B2 indicated by
the external thermometer. Enable 4-point linearization (see Correcting 4-point input) and enter the four requested values (A1, B1
and A2, B2)..
