■Setting the monitoring condition
• Set a condition to generate a hold trigger in 'CH1 Level trigger condition setting' (Un\G540).
Setting value
Level trigger (condition:
Rise) (1)
Level trigger (condition:
Fall) (2)
Level trigger (condition:
Rise and fall) (3)
• Set a value where a hold trigger is generated to 'CH1 Trigger setting value' (Un\G542).
Item
'CH1 Trigger setting value' (Un\G542)
The following figure shows the relation between setting items to be configured for the initial setting of a level
trigger.
To generate a hold trigger when a value in CH1 Measured temperature value is greater than 1000, set as
follows.
• 'CH1 Level trigger condition setting' (Un\G540): Rise (1)
• 'CH1 Trigger data' (Un\G541): 400
• 'CH1 Trigger setting value' (Un\G542): 1000
