FIELD: instrument engineering.
SUBSTANCE: invention relates to devices for receivers of seismic signals, namely, to testers providing verification of the correct operation of one or a group of electrodynamic seismometers (SMs). Tester of electrodynamic tester is claimed that contains a CI block of an interface controller equipped with an input for connection of a power supply source PSS and comprising a control unit CU, a digital conversion unit DCU provided with an input for connecting the power supply source and including an analog-to-digital converter ADC and a generator of test signals TG connected to the control unit CU. According to the solution, interface controller unit ICU includes network interface NI, thermal sensor TS and transient phenomena former TPF connected to control unit CU. Digital conversion unit DCU includes a switching and amplifying unit SAU provided with inputs connected to the control unit CU, transient phenomena former TPF, generator of test signals TG, and the analog-to-digital converter ADC, and also inputs for connection of one or several tested geophones.
EFFECT: increased accuracy of the tester operation.
