Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
brief introduction
ZC6061/ZC6062 series of standing microphone tester adopts advanced digital circuit design technology, mainly used in production line to measure the sensitivity of standing microphone at 100Hz, 1kHz, 5kHz frequency points, in order to be graded and matched according to the sensitivity detection. 100Hz, 1kHz and 5kHz signals are respectively indicated by three indicators, which can be indicated at the same time or separately. 100Hz and 5kHz can indicate both the sensitivity and their frequency response relative to 1kHz, when the frequency response exceeds the set value, there are sound and indicator alarm respectively. 100Hz and 5kHz can indicate both sensitivity and frequency response relative to 1kHz, when the frequency response exceeds the set value, there are sound and indicator alarm. The instrument is easy to operate, fast and accurate reading, high testing efficiency, but also has internal calibration, acoustic calibration function. Particularly suitable for resident microphone production line and telephone manufacturers outsourcing parts inspection, and has a HANDLER interface and RS-232 interface options, can be connected to the automatic test machine for rapid testing.
Performance Characteristics
