Resistance connection type (Inp.1 only)
0
3-wire connection
Normally, resistance and resistance thermometer measurements are in three-wire
technology, based on the assumption that the lead resistance in all supply leads is
equal.
1
4-wire connection
with measurement in four-wire connection, the lead resistance is measured via refe-
rence leads.
S.Lin
Linearization only adjustable with

none
1
Special linearization. Producing a linearization table is possible via BlueControl (Engi-
neering-Tool). Preset is the characteristic for KTY 11-6 temperature sensors.
Corr
Measured value correction / scaling:
When using current, voltage orr (version-dependent) resistance signals as input va-
riables, scaling at parameter level is possible. Specify the input value of the lower
and upper scaling point in units of the relevant electrical quantity (mA / V/ Ohm).
0
No correction
1
The offset correction (at CAL level) is possible on-line at the process. If InL shows the
lower input value of the scaling point, OuL must be set to the relevant display value.
Adjustment is via the instrument front panel.
2
2-point correction (at CAL level) is possible off-line by means of a process value
transmitter. Specify the process value for the lower and the upper scaling point and
confirm it as input value InL or InH. Now, adjust the relevant display value OuL or
OuH. Adjustment is via instrument front panel operation.
3
Scaling (at PArA level) for current and voltage signals as input variables also for re-
sistance signals dependent on version). The input and display value values for lower
(InL, OuL) and upper scaling point (InH, OuH) are visible at parameter setting level.
Adjustment is via instrument front panel operation, or via the engineering tool.

1
Measured value monitoring. When exceeding the limit value, an alarm is output and
reset automatically, when the measured value is "within the limits" (including hyste-
resis) again.
2
Measured value monitoring + alarm status latch
. A stored limit value can be reset by
pressing the RESET key or via the digital input (
LOGI/ Err.r).
3
Temperature monitor fo
r high limit value + latch: measured value monitoring + high
limit value alarm status latch. A stored limit value can be reset via a digital input or
by pressing the RESET key (-> LOGI/Err.r).
4
Temperature monitor for low limit value + latch: measured value monitoring + low li-
mit value alarm status latch. A stored limit value can be reset via a digital input or by
pressing the RESET key (-> LOGI/Err.r).
5
Temperature monitor function for exceeded high limit value. The limit value is not
stored.
6
Temperature monitor function for exceeded low limit value. The limit value is not sto-
red.
