The Ministry of Industry has requested the civil explosion industry to realize the full use of in-dustrial digital detonators,hich has promoted the upgrading for the electronic parameter tester in indus-trial digital detonators,and the original calibration method can not meet the requirements about source tracing.According to the working principle of the industrial digital electronic detonator electric parameter tester,the calibration method is studied from the parameters of delay time,DC resistance,DC current and internal crystal oscillator signal(frequency),the source of uncertainty of electrical parameter tester for industrial digital detonator is analyzed,and the problem of traceability of electrical parameter tester for industrial digital detonator in civil explosion industry is solved.
