■Resuming the logging
It may take time until ON (1) is stored in 'CH1 Logging hold flag' (Un\G409) after 'CH1 Logging hold request' (Un\G471) is
changed offon.
To resume logging, check that ON (1) is stored in 'CH1 Logging hold flag' (Un\G409) and 'CH1 Logging hold request'
(Un\G471) is changed from onoff. After logging resumes, the value is stored from the head buffer memory area of CH1
Logging data (Un\G10000 to Un\G19999).
In addition, OFF (0) is stored in 'CH1 Logging hold flag' (Un\G409).

which area has valid data with CH1 Number of logging data (Un\G436).
The logging does not stop.
