Settings

The following settings can be made for the sensor (default settings are
marked in bold):

Display indications for different settings of
Measuring range, Error threshold and Error detection:

Possible settings

Explanations

Measuring mode

REC

Measurement of the current at the
0/4 ... 20 mA current inputs

Measuring range

0..20 mA

4..20 mA

Two measuring ranges can be selected.
The setting should agree with the output
range of the external sensor.

Decimal places

none

1 (.0)

2 (.00)

3 (.000)

Display accuracy of the correlated mea-
sured value (display value).

The setting of the Decimal places affects
the maximum limits of the correlated mea-
sured value (see settings of display value).

Display value (0/4 mA)

depending on the setting of
the Decimal places:

-9999 ... 20 ... 99999

-99.9 ... 20.0 ... 999.9

-9.99 ... 20.00 ... 99.99

0.000 ... 2.000 ... 9.999

Lower and upper limit of the measuring
range for the displayed, correlated mea-
sured value.

The maximum measuring range limits to
be set depend on the setting of the
Decimal places.

Display value (20 mA)

Error detection

>= Error threshold

<= Error threshold

Specification whether an invalid measured
value ("----") is displayed if the current limit
value (Error threshold) is exceeded or un-
dercut
.

Error threshold

0.5 ... 20.5 ... 21.5 mA

Current limit value. If it is reached and ex-
ceeded
or undercut, an error should be
displayed (see setting of Error detection).
