• 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)”.
