dIP
Radix point
position
Four formats (0, 0.0, 0.00, 0.000) are selectable
dIP=0, display format is 0000, no radix point
dIP=1, display format is 000.0
dIP=2, display format is 00.00
dIP=3, display format is 0.000
Note 1: For thermocouples or RTD input, only 0 or 0.0 is selectable, and the
internal resolution is 0.1.
dIP only affect the display, and has no affect to the accuracy of measurement
or control.
0～3
dIL
Signal scale
low limit
Define scale low limit of input. It is also the low limit of external set value,
transmittion output and light bar display.
E.g.:pressure transmitter is used, 1-
5v input,as for 1V input is 0,5V is 1MPa,
hope to be resolution as 0.001MPa. Then you need to set as follows:
Sn=33(1-5v input)
Dip=3(0.000format)
dIL=0.000(input low limit is 1V)
dIH=1.000(input high limit is 5V)

dIH
Signal scale
high limit
Define scale high limit of input. It is also the high limit of external set value,
retransmission output and light bar display.
Sc Input offset
Sc is used to compensate the error caused by transducer, input signal, or auto
cold junction compensation of thermocouple.
PV_after_compensation=PV_before_compensation + Scb
E.g.:if
input is remaining same, Sc=0.0C, PV=500.0C, when Sc is 10.0, then
PV is 510.0C. Sc is usually 0.
