”OutP” menu
This menu contains parameters of analogue output control. Menu is available if the
device is equipped witch analogue output.
Analogue output can be controlled depend on both present measured value and
peak value (if peak detection is enabled).
“Omod”
- analogue output mode. Depending on version of the device there are following
options:
For active current output:
”
oFF
”
- current output disabled
,
”
0-20
”
- current output enabled with 0 ÷ 20 mA mode
,
“
4-20
”
- current output enabled with 4 ÷ 20 mA mode,
”
modb
”
- current output controlled via RS-485 interface.
For passive current output:
”
oFF
”
- current output disabled
,
“
4-20
”
- current output enabled with 4 ÷ 20 mA mode,
”
modb
”
- current output controlled via RS-485 interface.
For active voltage output:
”
oFF
”
- voltage output disabled
,
”
0-5
”
- voltage output enabled with 0 ÷ 5V mode
,
”
1-5
”
- voltage output enabled with 1 ÷ 5V mode
,
”
0-10
”
- voltage output enabled with 0 ÷ 10V mode
,
“
2-10
”
- voltage output enabled with 2 ÷ 10 V mode,
”
modb
”
- voltage output controlled via RS-485 interface.
”OUtL”
- this parameter determines the input value for which the output signal is
minimal
(depend of output mode „
Omod
”).
“OUtH”
- this parameter determines the input value for which the output signal is
maximal
(depend of output mode „
Omod
”).
The analogue output value is calculated due to formula given below:
Out
=
W
−
" OUtL"
"OUtH"
−
"OUtL"
×
B
−
A
A
where:
W
– displayed value,
Out
– analogue output value,
B
– higher range limit (20mA / 5V / 10V),
A
– lower range limit (0mA / 4mA / 0V / 1V / 2v),
“
OutL
” parameter can be greater than “
OutH
”. In this case the conversion
characteristic is reversed, it means that if input value raises the output value falls.
