    • A circuit for amplifying a weak direct voltage signal has a direct voltage amplifier that can be periodically switched from the direct voltage signal to a reference signal by a switching member connected to its input terminals. The circuit also has a measurement value processing device connected downstream of the direct voltage amplifiers. In order to obtain an amplified direct voltage signal closely approximating the weak direct voltage signal to be amplified, the switching member is arranged as a periodical shunt between the input terminals of the direct voltage amplifier.

    • A measuring device for the accurate adjustment of the start-of-measurement of a measuring transducer of two-conductor design is disclosed. The measuring device disclosed is of simple design, can be produced inexpensively and is highly accurate. In one embodiment of the measuring device, a pickup resistor is arranged in series with the measuring transducer. The input of a multivibrator is coupled to the pickup resistor. The duty cycle of the multivibrator changes as a function of the voltage at its input. The duty cycle is 1:1 for a current through the pickup resistor corresponding to the start-of-measurement. The multivibrator is coupled to a circuit having two light-emitting diodes which can be fed from the current flowing through the measuring transducer and which light up with equal brightness when the duty cycle is 1:1. The measuring device can be used with all measuring transducers of two-conductor design. In a further embodiment, the measuring device includes a differential amplifier arrangement having outputs coupled to a circuit having two light emitting diodes which light up with equal brightness when the start of measurement is attained.
