♦ <Signal output>
This parameter defines whether the DC output will be operated with an
offset (e.g. 4-20 mA, 2 -10 V) or without one (e.g. 0-20 mA, 0-10 V).
If either of the settings <4-20 mA / 2 -10 V> is selected, invalid
measurements / measurement outputs are signalled to the peripheral
electronic equipment as 2 mA - or 1 V - signals.
If either of the settings <0-20 mA, 0-10 V> is selected, when an invalid
measurement / measurement output occurs, the output signal will drop
to 0 V or 0 mA.
The setting of the signal output can be changed at the instrument.

♦ <X1, Y 1 ... X4, Y4>
These parameters are provided for setting the linearity of the DC output.
The setting of the DC output curve linearity can be changed at the
instrument.
With the setting of anchor points (X,Y) the output linearity is defined by
the anchor points. By entering more than two anchor points the output
curve will be made non-linear.
The following is generally valid for the output curves:
◊ At least 2 anchor points are required to put a DC output into
operation.
◊ A maximum of 4 anchor points can be defined for the output
curve.
◊ With more than 2 anchor points a “bend” is built into the output
curve.
◊ There is always a linear interpolation between the anchor points.
◊ The output of DC voltages and DC current always have the same
common output curve and cannot be set up separately.
The X-values of anchor points corresponds to the measurement in the
physical unit of the signal path.
The maximum value range is from -99999.99 to + 99999.99
◊ Maximum X-range: -99999.99 ≤ X ≤ + 99999.99.
that means: -99999.99 ≤ X1<X2<X3<X4 ≤ + 99999.99
