PURPOSE:To enable the detection of a peak at a high accuracy with a high invulnerability to noise corresponding to various input detection signals by displaying a difference signal between the input signal and the signal of a peak hold circuit while the input signal is displayed. CONSTITUTION:An input signal 1' as detection signal from a signal source 1 is inputted into a peak hold circuit 2, a differential circuit 3 and a second display 4 while an output hold signal 2' of the circuit 2 is inputted into the other input section of the circuit 3 and a differential signal 3' from the circuit 3 is inputted into a first display 5. Then, the signal 1' with the device 4 and the signal 3' with the device 5 are monitored to identify the peak of the input signal.
