Setting 3-gas mix
Use the grey scale to set the required CO
2
(O
2
) percentage. Then read the X -value in the lower
part of this scale. The setting of the green MIX scale is calculated on the basis of the
expression: MIX = N
2
divided by X. The O
2
(CO
2
) will constitute the rest.
Example 1: 60% CO
2
- 30% N
2
- 10% O
2
1. Set the CO
2
-dial at 60%
2. Read the value of X (4)
3. Calculate MIX: N
2
/ X = 30% / 4 = 7.5
4. Set the MIX -dial to 7.5
5. The O
2
gas constitutes the rest (10%)
Example 2: 30% CO
2
- 20% N
2
- 50% O
2
1. Set the CO
2
-dial at 30%
2. Read the value of X (7)
3. Calculate MIX: N
2
/ X = 20% / 7 = 2.86
4. Set the MIX -dial to 2.9
5. The O
2
gas constitutes the rest (50%)
Example 3 : 70% CO
2
- 20% N
2
, - 10% O
2
1. Set the CO
2
-dial at 70%
2. Read the value of X (3)
3. Calculate MIX: N
2
/ X = 20% /3 = 6.67
4. Set the MIX -dial to 6.7
5. The O
2
gas constitutes the rest (10%)
Example 4: 0% CO
2
- 30% N
2
- 70% O
2
1. Set the CO
2
-dial at 0%
2. Read the value of X (10)
3. Calculate MIX: N
2
/ X = 30% / 10 = 3
4. Set the MIX -dial to 3.0
5. The O
2
gas constitutes the rest (70%)
Example 5: 100% CO
2
- 0% N
2
- 0% O
2
1. Set the CO
2
-dial at 100%
2. Never mind MIX -dial setting
