A method is disclosed for calibrating a trigger unit which is connected via a trigger line to at least two sensors configured to be triggered. Each sensor is connected between two successive line portions of the trigger line. Each sensor has an input and an output, a controllable interrupter between the input and output; and a control circuit, which controls the interrupter. The interrupters of all sensors are initially open. The method comprises the following: transmitting a trigger pulse; in the sensor: receiving the trigger pulse and returning a response; in the trigger unit: receiving the response and calibrating the trigger unit; repeating the aforementioned steps, wherein each sensor reflects the trigger pulse, and the trigger unit measures the propagation times and is calibrated thereto. |
