*1 Set the offset value and gain value in the user range setting within the range satisfying the following conditions.
If the following conditions are not satisfied, A/D conversion may not be properly performed.
<User range setting 1>
• Setting range for offset value and gain value: -10 to 10V
• ((Gain value) - (Offset value)) ≥ 8.0V
• 10.433V ≥ (Gain value - (Offset value × 2))
<User range setting 2>
• Setting range for offset value and gain value: -5 to 5V
• ((Gain value) - (Offset value)) ≥ 4.0V
• 5.21V ≥ (Gain value - (Offset value × 2))
*2 When the analog input value exceeds the range of digital output values, the digital output value is fixed to the maximum
or minimum value.
