The main purpose of smart meters is to measure electricity, and they are the main bases of the settlement relation between power enterprise and users. One of the most parameters is time, and the crystal oscillator is one of key elements. So its accuracy and reliability directly are related to smart meter measuring whether a fair, impartial and accurate. This paper collected at home and abroad with crystal oscillator detection related standard, and the testing methods are put forward about the electric parameters, the mechanical characteristic parameters and environmental temperature parameters.
