6.11 Thermocouple 

If you connected the thermocouple supplied with the DT800 to analog input channel 7, then the 
temperature can be monitored by the command. (Prog18.dl8)

6.12 Scan 

Schedules 

The SSP can be used to demonstrate several of the scan schedule triggers available in the DT800 as 
follows: 

• 

6.12.1 

Poll trigger by host (Prog19.dl8) 

 

Fig. 30. 

 

Send X or XA command from host PC (DeLogger text window) to scan schedule 
 
 
 

• 

6.12.2 

Realtime trigger (Prog20.dl8)
