Analogue Comparator 1, Level Low [6113]
Sets the analogue comparator low level, with unit and range
according to the selected value in menu [6111].
Analogue Comparator 1, Type [6114]
Selects the analogue comparator type, i.e. Hysteresis or
Window type. See fig. 140 and fig. 141.
Analogue Comparator 1, Polarity [6115]
Selects how the selected value in [6111] should be handled
prior to the analogue comparator , i.e. as absolute value or
handled with sign. See fig. 140
Example
See fig. 140 and fig. 141 for different principle
functionality of comparator features 6114 and 6115.
Fig. 140 Principle functionality of comparator features for
“Type [6114] = Hysteresis ”and “Polar [6115]”.

No. Description
Window
1
The reference signal passes the Level LO
value from below (signal inside Window
band), the comparator CA1 output is set
high.
2
The reference signal passes the Level LO
value from above (signal outside Window
band), the comparator CA1 is reset, output is
set low.
3
The reference signal passes the Level HI
value from above (signal inside Window
band), the comparator CA1 output is set
high.
4
The reference signal passes the Level LO
value from above (signal outside Window
band), the comparator CA1 is reset, output is
set low.
5
The reference signal passes the Level LO
value from below (signal inside Window
band), the comparator CA1 output is set
high.
6
The reference signal passes the Level HI
value from below (signal outside Window
band),the comparator CA1 is reset, output is
set low.
7
The reference signal passes the Level HI
value from above (signal inside Window
band), the comparator CA1 output is set
high.
8
The reference signal passes the Level LO
value from above (signal outside Window
band), the comparator CA1 is reset, output is
set low.
