Figure 6.1. Definitions of measurement ranges in mode 4 ÷ 20mA
If the result of measurement exceeds the
permissible measurement range
, warning
”-Hi-”
or
”-Lo-”
is displayed rather than input signal,
depends on exceeded value (see description of
“Lo r”
i
“Hi r”
parameters, paragraph
”inPt” menu
).
Figure 6.2. Definitions of measurement ranges in mode 0 ÷ 20mA
If the measurement value do not exceeds
permissible measurement range
but
displayed value exceeds range -999 ÷ 9999, the warning ”-Ov-” is displayed rather
than the calculated result.
Input type, range of displaying values, characteristic of conversion, decimal point position
and measure filtering ratio, are user configurable parameters. All accessible parameters can
be changed by entering the menu (see:
DEVICE PROGRAMMING
). Use the local keyboard or
the remote controller to do it. (Note: all parameters can be remote changed via RS-485
interface).
