CX-QWA-5 Inductive Quartz Clock Tester

CX-QWA-5 Inductive Quartz Clock Tester

The CX-QWA-5 Inductive Quartz Clock Tester is used to measure the time difference of the quartz crystal when it is powered on the circuit board (in oscillation working state) through induction. There is no parameter of load capacitance, because the induction is the actual oscillation frequency of the crystal. As long as the instrument is qualified, the data measured by different clock testers using induction methods is basically the same. It is mainly used to test the time measurement accuracy of various meters: daily difference/monthly difference/annual difference/PPM value
