Settings MIQ/IC2
4 - 2 ba76034e01 01/2012
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:
Fig. 4-2 Measuring range 0... 20 mA, Error detection >= Error threshold (IF),
IF = 20.5 mA
Menu item 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).
