A/D Conversion Method

An A/D conversion method can be set for each channel. The following shows available conversion methods.
• Sampling processing
• Averaging processing (time average, count average, moving average)
• Primary delay filter
Overview of A/D conversion
The A/D conversion is executed per channel.
■Sampling cycle
Sampling cycle is the internal A/D conversion cycle. The sampling cycle is fixed to 80ms regardless of the settings of the
number of conversion enabled channels.
■Conversion cycle
Digital output values are updated on the conversion cycle of sampling processing, averaging processing, or primary delay
filter. The following table lists the conversion cycles in each A/D conversion method.
