Abstract

PURPOSE:To carry out the indicating value adjustment without using a reference signal light and standard reference light by performing a zero point adjustment and a span adjustment during the formation of the measuring device. CONSTITUTION:The output of the signal light detecting device 10 is input to a numerator input terminal 20 of a dividing circuit 16 through a switch S1, an amplifier 12, an integrator 14, a switch 24. On the other hand, the output of the reference light detecting device 11 is input to a subtractor 25 through the amplifier 13, the integrator 15, compared with the constant voltage power source 26, the comparison signal obtained as a difference voltage is added to a pulse generating circuit 27 to be a driving source of the laser light source 1 and the pulse number per unit time is controlled. The output terminal 22 of the dividing circuit 16 is connected to a primary side terminal 29 of the switch S3. The primary side of the switch S3 has other two terminals 30, 31 respectively connected to the zero adjusted reference power source 32 and the span adjusted reference power source 33. The secondary side terminal of the switch S3 is connected to an indicator 19 through a logarithm amplifier 17, a variable resistor 18, and a switch S4.
