ABSTRACT:
A digital indicating instrument for a physical training device, in particular a rowing device, includes a sensor fixed rigidly to a basic frame of the training device and sensor trip element fixed to an operating part, in particular to a sliding seat of the rowing device. An evaluation circuit responds to control pulses generated by the sensor during the passing movement of the trip element and determines together with the training time output-related data, which are displayed on a display screen. A training time measuring device is started by control pulses of the sensor for an automatic determination of the training time. A stop device stops the training time measuring device if within a preset time interval no control pulse is generated by the sensor. A suppressor suppresses at the start of training at least the first control pulse, in order to prevent unintentional starting of the training time measuring device.
