■Operations of CH1 Maximum value (Un\G404) and CH1 Minimum value (Un\G406)
When the difference conversion starts, the maximum value and the minimum value of the values acquired by the difference
conversion are stored in 'CH1 Maximum value' (Un\G404) and 'CH1 Minimum value' (Un\G406). By turning on 'Maximum
value/minimum value reset request' (YD), the maximum value and the minimum value after the start of the difference
conversion can be checked.
When 'Maximum value/minimum value reset request' (YD) is not turned on, the maximum values and minimum values before
and after difference conversion are mixed.
■Operation of when the averaging processing is set
If the difference conversion starts after the averaging processing is set, the digital operation value at the completion of the
averaging processing is determined as 'CH1 Difference conversion reference value' (Un\G432). 'CH1 Difference conversion
status flag' (Un\G408) turns to Converting difference (1).
• The difference conversion function can be started at any timing.
• When the difference conversion function is used with the digital clipping function, scaling function, and shift
function, each digital operation value is determined as a difference conversion reference value and used for
the difference conversion.
• Even though the digital clipping function, scaling function, and shift function are enabled during the
difference conversion, the value in 'CH1 Difference conversion reference value' (Un\G432) is not updated.
To update the value in 'CH1 Difference conversion reference value' (Un\G432), stop the difference
conversion and restart it again.
