E denotes output from a lighting period control circuit 8. More specifically, a signal (a) is output for 3min from turning-on of the switch signal A to issuance of the B signal, a signal (b) is output for a period from issuance of the B signal to that of the C signal, a signal (c) is output for a period from issuance of the C signal to that of the D signal, and a continuous ON signal is output after the D signal, i.e., after 10min has lapsed from turning-on of the switch signal A. For 3min from turning-on of the signal A to issuance of the signal B, the measured result is indicated while being turned on for 1sec and off for 3sec. Such longer lighting period than non-lighting period informs that the measuring time is not yet sufficient.
