longer the updating time of the displayed value and the alarm set-point.

NOTE: for a correct working of the filter, the relative coefficient must

satisfy the following relationship: 1 ≤ Fi.C ≤ (Fi.S x 8) ≤ 255.

Example: in order to display a temperature with a resolution of 0.1 °C, set

“Lo.E”=-20 °C ⇒ “Lo”=-20.0 °C, “Hi.E”=200 °C ⇒ “Hi”=199.9 °C. In this

case the scale ratio will be 10 times with a clear fluctuation of the value

displayed in the measuring phase. In order to stabilize the value it is

necessary to enter the parameters “Fi.S” and “Fi.C”. The value fluctuates

of 0.5°C max., therefore “Fi.S”=0.5 and the filtering coefficient is to be

entered making various attempts starting from a minimum value, for

example “Fi.C”=3. The datum will not remain stable, therefore “Fi.C” is

to be increased; in our case the optimum value is “Fi.C”=15.

End : Selection of the exit from the programming phase.

Diagnostic messages

“EEE” blinking indication: burn-out “up” or overcoming of the displaying

range (value to be displayed > 1999/9990).

“-EE“ blinking indication: burn-out “down” or overcoming of the display-

ing range > -1999/1990).

“3 or 4 blinking points“ indicate the set-point activation.
