a device for monitoring an operating condition is incorporated in a balance with a weighing cell , an electronic weighing circuit arrangement , an output unit , and at least one electronic inclination sensor . the circuit arrangement includes a signal - processing device , a memory device as well as a time clock . based on a sensor signal received from the electronic inclination sensor , the signal - processing device determines a quantity that is indicative of the operating condition of the balance . the signal - processing device also determines the current time and assigns a time value to the quantity that represents the operating condition . the resultant vector - like sets of time and operating condition data are transmitted to and stored in the memory device , so that the data are at all times available for transmission to an output unit .
