Description
Measurement
offset
OFFS
-1999…0…+9999
The measurement offset is used to correct a measured
value by a certain amount upwards or downwards.

Special cas:2-wire circuit
If the input is connected to a resistance thermometer in
2-wire circuit, then the lead resistance is set in ohms
here.

SCL
-1999…0…+9999
On transducers with standard signal and on
potentiometers, a display value is assigned to the
physical signal.
Example: 0 — 20mA � 0 — 1500°C.
The range of the physical signal can be 20 % wider or
narrower without generating an out-of-range signal.

Filter time

dF
0…0.6…100 s
To adjust the digital input filter (0sec = filter off).
63% of the alterations are acquired after 2x filter time
constant at a signal step change.
When the filter time constant is large:
- high damping of disturbance signals
- slow reaction of the process value
display to process value changes.

Output 1—10
The heater current is measured via a current transformer
with standard signal output and can be monitored by
linking analog output 2 to a limit comparator.
The input signal range is 0 — 50mA AC (see probe type:
“Heater current”) and must be scaled correspondingly
(display start/end).
The heater current is measured when the heating contact
is closed.
