00:00:25,052 --> 00:00:27,679
Introducing “Distance” room, Part II:

2
00:00:27,704 --> 00:00:32,613
In “Zone Setting” tab and in “Zones” section, the information is entered to each “Zone”.

3
00:00:32,638 --> 00:00:39,595
By using the “New” option, it is possible to add a row or “Zone” to the table of this section and to repeat a zone,

4
00:00:39,620 --> 00:00:47,104
delete a zone or enter the characteristics of each “Zone” you can use “Add Duplicate”, “Delete” and “Edit” options respectively.

5
00:00:47,129 --> 00:00:53,742
To enter the characteristics of a “Zone”, by clicking on “Add” add one or several rows and specify your zone.

6
00:00:53,767 --> 00:00:56,730
Using this table, you can draw the desired characteristics.

7
00:00:56,755 --> 00:01:02,159
For polygon characteristics you need to use several “Lines” and enter the characteristics of each of the sides.

8
00:01:02,184 --> 00:01:11,754
For each line, “R”, “X”, “Angle (angle of the line)” and “Inside (the inside area)” should be specified which includes “Left” for the area of the left side (and above the line for horizontal lines) and “Right” (and below the line for horizontal lines).

9
00:01:11,779 --> 00:01:18,889
In using “Line polar”, the line characteristics are specified with its impedance magnitude and angle which means “Z” and “Phi”.

10
00:01:18,913 --> 00:01:22,321
If you wish to draw radial characteristics, you need to use “Arc”.

11
00:01:22,345 --> 00:01:35,714
In “Arc” mode, you need to enter the center of the circle, the radius of the circle, the start angle of the curve and the end angle of the curve in “R” and “X”, “Radius”, “Start angle” and “End angle” respectively.

12
00:01:35,738 --> 00:01:42,890
Moreover, you can select the rotation direction of the curve i there “Clockwise” and “Counter clockwise”.

13
00:01:42,914 --> 00:01:48,356
”. If you are using “Arc Polar”, instead of “R” and “X”, you need to enter impedance and angle.

14
00:01:48,380 --> 00:01:57,818
As an example, we are going to show you how to draw a “Quad” characteristic and in future videos we will provide you with explanations for other characteristics.

15
00:01:57,842 --> 00:02:10,621
Before starting to design the zones, it is important to note that intersection of successive lines with each other, meaning the intersection of the first and second lines, second and third lines, and third and fourth lines so one .

16
00:02:10,645 --> 00:02:11,553
make the zone.

17
00:02:11,577 --> 00:02:19,808
Finally, if you check “Auto Close” option, the intersections of the first and last lines will be considered as well and the zone will close automatically.

18
00:02:19,832 --> 00:02:28,536
To begin an element, “Add” “Line Cartesian” and set its “R” and “X” at “0” and “-0.1” respectively with a “0” angle.

19
00:02:28,560 --> 00:02:33,945
By adding the next line, the intersection point of these two lines determines the zone area.

20
00:02:33,969 --> 00:02:38,959
“R” and “X” of the second line are “1” and “0” with a “65” angle.

21
00:02:38,983 --> 00:02:43,628
Since “Left” has been selected, the inside area of the left side is selected.

22
00:02:43,673 --> 00:02:50,072
By selecting “Right”, you can see that the right side of the line from the intersection point is considered as a part of the zone.

23
00:02:50,096 --> 00:02:58,157
To specify the line above the characteristic, a line with “0” as “R” and “1” as “X” with a “0” angle and “Right” (to select below the line) is entered.

24
00:02:58,181 --> 00:03:06,183
In the final step, a line with “65” as its angle and “-1” and “0” as its “R” and “X” are entered.

25
00:03:06,207 --> 00:03:11,701
As another example, if you wish to make a radial zone, you need to use “Arc Cartesian”.

26
00:03:11,725 --> 00:03:16,358
If you just want to make a circular zone with a specified center and radius,

27
00:03:16,382 --> 00:03:22,860
you need to enter the center of the circle and its radius in “R” and “X” and “Radius” fields respectively.

28
00:03:22,884 --> 00:03:27,760
Here, as an example, “1”, “0” and “1” are entered as the center and radius.

29
00:03:27,784 --> 00:03:32,298
“Start Angle”, “End Angle” and “Direction” fields have no effect in this mode.

30
00:03:32,322 --> 00:03:39,140
In “Inside” field, by selecting “Left” or “Right” you can select inside or outside the circle as the zone respectively.

31
00:03:39,164 --> 00:03:45,274
If you wish to specify a part of the circle as the zone, first you need to specify a line and then a circle.

32
00:03:45,298 --> 00:03:52,755
If you enter “15” degrees as the angle of the first line, and set the rotation direction of the circle at “Counter Clockwise”,

33
00:03:52,780 --> 00:04:01,722
the software starts moving in counter clockwise direction and picks the first intersection of the line and the circle which is close to the “Start Angle” as

34
00:04:01,746 --> 00:04:06,974
the start angle and picks another intersection which is close to the “End Angle” and the end angle.

35
00:04:06,998 --> 00:04:14,157
To complement the explanation, another line is added.  This line determines the end angle and the first line of the start angle.

36
00:04:14,181 --> 00:04:20,639
Like before, the rule is that the intersection which is close to the “End Angle” is considered as the end angle.

37
00:04:20,663 --> 00:04:23,412
For example, “25” degrees is entered.

38
00:04:23,436 --> 00:04:28,782
According to the provided explanations, if you wish to select a part of the circle as the zone,

39
00:04:28,806 --> 00:04:37,275
you need to specify the Arc element between the two line where the first line is the start angle and the second line is the end angle.
