The next screen shows the self-check cycle time being used. This value is displayed and entered in
seconds. For example, two minutes is entered as 120 seconds. The self-check cycle time is restricted to
a minimum value of 30 seconds and a maximum value of 600 seconds (10 minutes).
During self-check the detectors are blinded for a brief interval. After a short delay, the signal levels are
compared and self-check failure occurs if a detector’s output is above its dropout point. The Blind function
for an IDD detector head has the 50Vdc bias Voltage removed.
Example set SELF CHECK Delay to 5 minutes.
