set automatically P44 = P45 = FLtr. For all the remaining
ranges it will set P44 = P45 = nOFL.
P2 = Decimal point position P2 = Decimal point position P2 = Decimal point position P2 = Decimal point position P2 = Decimal point position
This parameter is available only when a linear input is
selected (P1 = 12, 13, 14, 15, 16, 17, 18 or 19).

P3 = Initial scale value
For linear inputs it is programmable from -1999 to 4000.
For TC and RTD input it is programmable within the input
range.
Notes:
1) When this parameter is modified, rL parameter will be
re-aligned to it.
2) If a linear input is selected, the value of this parameter
can be greater than P4 in order to get a reverse
readout.
P4 = Full scale value P4 = Full scale value P4 = Full scale value P4 = Full scale value P4 = Full scale value
For linear inputs it is programmable from -1999 to 4000.
For TC and RTD inputs, it is programmable within the
input range.
Notes:
1) When this parameter is modified, rH parameter will be
re-aligned to it.
2) If a linear input is selected, the value of this parameter
can be smaller than P3 in order to get a reverse
readout.
The initial and full scale values determine the input span
which is used by the PID algorithm, the SMART and the
alarm functions.

+2550 °F NOTE: the minimum input span (S = P4 - P3), in absolute NOTE NOTE NOTE NOTE
+3200 °F value, should be set as follows:
+3200 °F - For linear inputs, S > 100 units.
+400.0 °F - For TC input with °C readout, S > 300 °C.
+1470 °F - For TC input with °F readout, S > 550 °F.
- For RTD input with °C readout, S > 100 °C.
- For RTD input with °F readout, S > 200 °F.
