■Operations when an input signal error occurs
When an input signal error occurs, even if 'CH1 Difference conversion trigger' (Un\G470) changes from No request (0) to
Trigger request (1), the difference conversion does not start. After the input signal error returns to the normal value, change
'CH1 Difference conversion trigger' (Un\G470) from No request (0) to Trigger request (1) again. If an input signal error occurs
in the status of Trigger request (1), the difference conversion starts at the timing when the input signal error returns to the
normal value, treating the digital operation value as the difference conversion reference value.
