Abstract

An electronic survey instrument is controlled in accordance with a computer program to store a display image and a count value immediately before a power source is cut off. The display image and count values may then be restored without substantial initialization of the electronic survey instrument. The instrument includes a main system for operating in accordance with a survey program, and plural subsystems for operation based on a control signal from the main system. The main system saves information into a memory immediately before a power-off time and restores the information saved in the memory at the next power-on time. End information corresponding to the saved information is also saved into the memory to normally cut-off the power source. An information restoring process is canceled by the main system at the next power-on time when the end information has not been stored in the memory.
