ABSTRACT:
A test signal is applied in parallel with an electrochemical gas sensor for about ten seconds, while an amplifying circuit is turned off. After turning off the test signal, the amplifying circuit is turned on. If the gas sensor outputs an waveform of a predetermined shape in a predetermined period after the turning-on, the gas sensor will be judged to be normal.
