ENGLISH

• corresponding values (Lo.E = Lo, Hi.E = Hi), if the same value is to be

both measured and displayed.

• different values, if the signal to be measured is different from the one

to be displayed (see examples of “Lo” and “Hi”).

• inverted values, if an increasing signal to be measured must corre-

spond to a decreasing value to be displayed (scale inversion).

Example:

“Lo.E”=4.00 mA ⇒ “Lo”=1800 mbar; “Hi.E”=19.99 mA ⇒ “Hi”=0 mbar,

means that when the measured value increases from 4 to 20mA, the

displayed value decreases from 1800 mbar to 0.

As you can see, the scales can be programmed with absolute freedom.

NOTE: to display temperature values as “°F”, it is necessary to program

the electrical scale as “°C” and enter the values for the displayed scale

according to the following relationship:

°F = (1.8 x °C) + 32.

Example:

“Lo.E”=-50 °C ⇒ “Lo”=-58 °F; “Hi.E”=+760 °C ⇒ “Hi”=+1400 °F,

means that the new measuring range becomes -58 °F to +1400 °F. The

data to be entered in the displayed scale can be calculated either by

means of the above mentioned “°F” relationship, or using the data of the

relevant measuring range (see chapter “Technical Features”, paragraph

“Inputs (temperature)”.

diS : menu to select the displaying mode.

35 : displaying at 3

digit (1999)

30 : displaying at 3 digit + dummy zero (9990).

SP.1 : menu to select the programming of the set-point parameters.

tYP : selection of the type of control.

oFF : signalling of the abnormal condition. The relay is activated when

a burn-out condition occurs or the measurement is out of the electrical
