Abstract

A method of using a collection apparatus as well as the collection apparatus itself. The latter includes collection receptacles, a drip nozzle, and a component for bringing about a relative movement between the receptacles and the drip nozzle at predetermined times to collect the drops emitted by the drip nozzle, in the different receptacles. The time between the drops is measured by a time measurement circuit. The lower and the upper time limits for a time interval within which the next drop is expected, are calculated by a time limit calculating circuit. A blocking circuit is adapted to compare the time measured after the latest drop with the calculated time limits, and to block the relative movement when the measured time lies between these time limits. The blocking circuit is adapted to permit the relative movement when the expected drop has been emitted within the time limits.
