Example
ARIT1: C0338
0
OUT = IN1
Note: IN2 will not be processed
1
OUT = IN1 + IN2
100% = 50% + 50%
2
OUT = IN1 − IN2
50% = 100% − 50%
3
OUT [inc] = IN1 [inc]
´IN2 [inc] ¸16384
OUT [%] = IN1 [%]
´ IN2 [%] ¸100
100% = 100%
´100% ¸(100)
4
OUT [inc] = IN1 [inc]
´16384¸100 ¸ ½IN2½[inc]
OUT [%] = IN1 [%]
¸ ½ IN2 ½[%]
1% = 100%
¸100%

OUT [inc] = IN1 [inc]
´16384 ¸ (16384 − IN2 [inc])
OUT [%] = IN1 [%]
´ 100 ¸ (100 − IN2 [%])
