| Abstract: | The domestic laser distance measuring instrument can not be widely used in field working due to the troubres happened at times. The paper taking HQ-102 type of laser distance measuring instrument as example briefly explains the troubles often happened during application, such as frequency drift, unlock of phase lock circuit, displacement of inside=cheeking prisim ete. and presents the corresponding removing methods. |
