■Operations of when 'Operating condition setting request' (Y9) is turned on and off
• During the difference conversion, even when 'Operating condition setting request' (Y9) is turned on and off, the difference
conversion continues without updating the difference conversion reference value. To update the difference conversion
reference value, restart the difference conversion by changing 'CH1 Difference conversion trigger' (Un\G470) from Trigger
request (1) to No request (0), and Trigger request (1) again.
• Difference conversion trigger is not enabled even though the trigger changes from No request (0) to Trigger request (1)
while 'Operating condition setting request' (Y9) is on. After turning on and off 'Operating condition setting request' (Y9),
change 'CH1 Difference conversion trigger' (Un\G470) from No request (0) to Trigger request (1) again.

■Operations of Maximum value and Minimum value
Once the difference conversion is started, 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 the difference conversion are mixed.
