will give a bargraph with no segments lit at a 7 segment display reading of

0

and all

segments lit with a 7 segment display reading of

100

.

S.dot

- single dot display. A single segment will be lit to indicate the input readings position

on the scale. When scaling the display use the

bAr_

and

bAr~

functions e.g.

bAr_

=

0

and

bAr~

=

100

will give a bargraph with the bottom segment lit at a 7 segment

display reading of

0

and the top segment lit with a 7 segment display reading of

100

. Note:

this could also be set up as a centre zero single dot display by entering a negative value and
positive value. e.g.

bAr_

=

-100

,

bAr~

=

100

.

d.dot

- double dot display. Two segments will be lit to indicate the input reading position

on the scale. The reading should be taken from the middle of the two segments. When scaling
the display use the

bAr_

and

bAr~

functions e.g.

bAr_

=

0

and

bAr~

=

100

will

give a bargraph with the bottom two segments lit at a 7 segment display reading of

0

and

the top two segments lit with a 7 segment display reading of

100

. Note: this could also be

set up as a centre zero double dot display by entering a negative value and positive value.
e.g.

bAr_

=

-100

,

bAr~

=

100

.

C.bAr

- centre bar display. The display will be a solid bargraph but will have its zero point

in the middle of the display. If the seven segment display value is positive the bargraph will
rise. If the seven segment display value is negative then the bargraph will fall. When scaling
the display use the

bAr_

and

bAr~

functions e.g.

bAr_

=

0

and

bAr~

=

100

will give a bargraph with all the bottom half segments lit at a 7 segment display reading of

-100

and all the top segments lit with a 7 segment display reading of

100

.

r.dot

- modulus or wrap around single dot bargraph. This mode of operation allows the

bargraph to wrap around the limits set by the

bAr_

and

bAr~

functions by dividing

the 7 segment display by the modulus (the modulus is the difference between 0 and

bAr~

) and displaying the remainder. For example if

bAr_

is set to

0

and

bAr~

is set to

10

then in other bargaph modes when the 7 segment display reads a value such as

25

the

bargraph would be stuck at the high limit of its travel since it cannot go beyond

10

. In

r.dot

mode the display will wrap around at

10

then continue up the bar again and will be

at the midpoint of the bargraph when the 7 segment display shows

25

(as it would for a 7

segment display of

15

,

35

, etc.). In this example for a 7 segment display of

25

the value of

25 is divided by the modulus value of 10 in this example and the remainder displayed i.e. 10
goes into 25 twice with the remainder of 5 and so a bargaph position of 5 is displayed. This
mode will operate on both vertical and circular bargraph type displays.
