Turning the ERROR Signal OFF
The ERROR signal turns ON when an error occurs.
After removing the cause of the error, turn the ERROR signal OFF using one of the following methods.
Method 1: Input an error clear command from an external device such as a PLC.
Method 2: Input a measurement trigger again.
(For example, turn the TRIG signal ON during a one-shot measurement.)
The ERROR signal will turn OFF when measurement is executed correctly.
