10.2.2 Starting Inspection - Repeat
If "Start" is set to "Repeat", after the PV310 is activated, the PV starts an inspection without waiting for START
signal (STA) input from the external device. After the first inspection is completed and READY signal is recovered,
READY signal turns off and the device executes an inspection without waiting for the next START signal input.
To stop the inspection, execute one of the following,
•
Input the START signal
•
Send "%SCR " (a serial command)
•
Press the A key of the keypad for one second
If one of the above is operated again after the inspection stopped, inspection will be repeatedly executed.
