The invention provides a set for calibrating a tester of an arrester counter. The set comprises a standard impact generator, a direct-current boost control circuit, a standard power frequency source, a data collecting module, a comprehensive intelligent processing unit, control buttons, a liquid crystal display and an upper computer waveform analysis module. The data collecting module, the control buttons, the liquid crystal screen and the upper computer waveform analysis module are all connected with the comprehensive intelligent processing unit. The standard impact generator is used for generating impact voltage wave or impact current wave according to preset voltage preset via the control buttons; the standard impact generator is used for generating standard power frequency current; the signal output end of the standard impact generator and the signal output end of the standard power frequency source are connected with the data collecting module. The set has the functions of outputting and measuring impact voltage and current and outputting and measuring power frequency voltage and current, is small in size, light in weight and convenient to carry and allows convenient field testing.
