PURPOSE:To shift recording without the generation of hunting by switching the connection between the output terminal of an attenuator and the input terminal of the body of a recorder by a switching circuit with hysteresis according to the size of the voltage of a measurement signal. CONSTITUTION:When a measurement input signal is 0-6V, the measurement input signal is recorded as it is F-G. When the measurement input signal exceeds 6V, the voltage obtained by subtracting a standard voltage 5mV from the measurement input signal is inputted to the body of recorder and the records are shifted as shown by H-K. When the measurement input signal falls below 5V, a switching circuit with hysteresis is changed over so that the switching circuit inputs the measurement input signal as it to the recorder and records L-P are obtained. |
