“Lo r”, ”Hi r”
- these parameters define the expansion of nominal range in percent. They determine the permissible range of
input signal (Figure 7.1).
The permissible range allow user to exceed the
nominal range
of input signal. If input value is contained in the
permissible range a proper result is displayed. If input signal exceeds this range (defined by

The
“Lo r”
parameter is important if input is set to
“4-20”
mode only, and determines lower border of the
permissible range. If input is set to
“0-20”
mode, lower border of the permissible range is always 0mA. If input is
set to
“4-20”
mode, the lower border is calculated due to expression:
The
“Lo r”
value can be set from 0 to 99.9%. Parameter
“Hi r”
determines the upper border of the permissible
range accordingly to the expression (for both
