Value range
(factory-setting in bold)

7.2.3

Offset 1

Using Offset1, a measured value at the analog input

can be corrected by the value entered above the total

measuring range.

-999.9 to 0.0 to 999.9

7.2.4

Lead wire resistance 1

Analog-input1 lead wire resistance
in 2-wire circuit

This value is used to compensate the resistance of the

probe line and depends on the line length.

Enter the ohmic resistance of the probe line here to

achieve the best possible temperature measurement.

0.0

to 30.0 ohm

7.2.5

Filter time 1

Time constant of the digital input filter
2nd order for analog input 1

If the input signal changes suddenly, approx. 26 % of

the change is recorded following a period that corre-

sponds to the filter time constant dF (2 x dF: approx.

59 %; 5 x dF: approx. 96 %).

Value 0 means: filter switched off

If the filter time is long:

- Interfering signals are better absorbed

- Measured value display responds more slowly to

changes

0.0 to 0.6 to 100 sec.

7.2.6

Scaling start 1

Important information:

This setting only occurs if the

sensor type 1 was set to 4 to 20mA!
Here, the user selects which value (i.e. pressure)

should be displayed at 4 mA.

-9999 to 0 to 9999

7.2.7

Scaling end 1

Here, the user selects which value (i.e. pressure)

should be displayed at 20 mA.

-9999 to 100 to 9999
