This paper introduces using Casio fx-4850P calculator to adjust height control network by indirect adjustment method.Using the characteristic which the matrix of coefficients of normal equation is symmetry and positive define,the matrix of coefficients of normal equation is created directly.The capacity of Casio fx-4850P calculator is just 28500 bytes.So thinking that the field work is amulatory and restricted by condition,this calculator can contain common survey calculating programs,and it is portable and calculating expediently.This program endures the practical calculating tests.The precision and practicability is very good.
