CH1 Digital operation value
High speed Medium speed
A digital operation value obtained by the scaling function, shift function, digital clipping function, or difference conversion
function is stored as a 16-bit signed binary value.

■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Digital operation value
■Updating cycle
When time average or count average is performed, values are updated at every averaging process cycle. When the
processing other than them is performed, values are updated at every sampling cycle.
High speed
If CH Logging enable/disable setting is set to High speed continuous logging (2) for any channel, the digital operation values
are simultaneously updated in all channels at intervals of 5ms.
When the scaling function, shift function, digital clipping function, or difference conversion function is not used,
a value same as the one in 'CH1 Digital output value' (Un\G400) is stored. However, when the normal mode
(high speed: 1s/CH) is used, the same value is not stored since 'CH1 Digital output value' (Un\G400) cannot
be used. 0 is always stored in 'CH1 Digital output value' (Un\G400).
