Abstract

A clock having an in-built electronic calculating circuit (7) and a display unit (4) visualising the calculated result has a switch (8, 8', 12) allocated to the measurement input of the calculating circuit. This switch (8, 8', 12) is briefly closed manually at every beat. The calculating circuit (7) sums up the pulses generated by actuation of the switch (8, 8', 12), calculates the pulse rate from this and displays the latter. <IMAGE>
