(b) When using the user range setting for the input range
The setting range allowed for the scaling upper and lower values is -32000 to
32000. Note that the resolution will not change even if a scaling upper/lower limit
value is set to change more than the resolution.
DX : Digital output value
D
MAX :
The maximum digital output value in the input range being used
(A/D conversion value corresponding to the gain value)
S
H : Scaling upper limit value
S
L : Scaling lower limit value
Example) On the Q68AD-G, using the scaling function in High resolution mode
and in the user range setting
If the setting is
Scaling upper limit value, S
H: 10000
Scaling lower limit value, S
L : 2000
and the digital output value 4250 is input,
Scaling value =
D
X × (SH-SL)
D
MAX
+ SL
Scaling value =
= 4833.33....
= 4833
It omits digits below the decimal point.
4250×(10000-2000)
