AR-C260/C260M SETTING AND ADJUSTMENTS 8 - 12
(3) How to calculate the adjustment value
New adjustment value = Current adjustment value + Rough adjustment
pattern reading value + Fine adjustment pattern reading value
pattern reading value + Fine adjustment pattern reading value
A: Current adjustment value
B: New adjustment value
X: Fine adjustment pattern reading value
Y: Rough adjustment pattern reading value
The polarity of the calculation differs depending on the polarity of the
adjustment pattern reading values. There are following four cases:
adjustment pattern reading values. There are following four cases:
1) When Y
≥
0, and X
≥
0:
B = A + X + Y
2) When Y
≥
0, and X < 0:
B = A + (X + 20) + Y
3) When Y < 0, and X
≥
0:
B = A + (X – 20) + Y
4) When Y < 0, and X < 0:
B = A + X + Y
Example
A: Providing that Current adjustment value = 48:
1) When Y
≥
0, and X
≥
0:
B = A + X + Y = 48 + (4) + (20) = 72
2) When Y
≥
0, and X < 0:
B = A + (X + 20) + Y = 48 + (– 6 + 20) + (20) = 82
3) When Y < 0, and X
≥
0:
B = A + (X – 20) + Y = 48 + (7 – 20) + (–20) = 15
4) When Y < 0, and X < 0:
B = A + X + Y = 48 + (–5) + (–20) = 23
