PURPOSE:To restart instantly an automatic analysis in case of a break of a power supply of a short time by setting a time required for stabilizing a device after turning on the power source again, basing on a cutting-off time of the power source. CONSTITUTION:When a power source is cut in the course of a measurement, a time counter receives a battery current and starts a time measurement, a transmitter 86 outputs one pulse to a binary counter 88 at every one minute, and the counter 88 counts the number of pulses and outputs a count value of the first to the seventh bits to a gate 94, and the eighth bit to a D-type FF90. On the other hand, when the power source is reset, a microcomputer selects a decoder 92 through a CPU bus 82, obtains a time counting value generated by a counter 80 and the FF90 by reading out the output of the gate 94, and the computer reads out a counting value corresponding to cutting-off of the power source from the time counter and compares it with a power source cut time stored in a memory in the computer. Subsequently, an initializing function corresponding to the power source cut time is executed and after the power source has been reset, a measurable state can be obtained in a short time. |
