Depending on the connected sensor type
(defined range of the sensor)
Parameterizable for application within the
measuring range program: Basis for the
trimming functions (see chapter 3, page 88).
Temperature linear
Linear: 1 resistance based sensor in two,
three or four-wire circuit
Standard (logic channel 1), averaging con-
nection or differentiating connection (of 2
channels)
1 resistor in two, three or four-wire circuit
Averaging connection between two resistors
in two-wire circuit, parameterizable equivalent
value behavior (e. g. the value of the other
channel is output if the channel is defective)
Differentiating connection between two resi-
stors in two-wire circuit, difference is parame-
terizable (e.g. channel 2 – channel 1)
Series or parallel circuit of several resistors in
two-wire circuit, e.g. to adapt other transmitter
types is implemented as an additional func-
tion. This gives a scaling factor.
Parameterizable line resistance ≤5 % of the
measuring range
No adjustment necessary. The line
resistances between the respective sensor
connection and the appropriate connection to
the transmitter must be the same.
No adjustment necessary.
≤0.55 mA
