Laboratory task5.1 Research the counter. Establish a correspondence between governments, shown on the front panel of the device and the structural scheme (pic 1). 5.2 To make the external research of EFC in self-control mode. 5.3 To make research in all work modes. 5.4 In frequency measurement mode perform validation of feature selection on the frequencies given in table 1 (appendix A). The results show in table 5.1.
Table 5.1 – Basic characteristics evaluation in “FREQUENCY MEASURMENT” mode.
5.5 In period measurement mode perform the same measuring. The results show in table 5.2.
Table 5.2 – Basic characteristics evaluation in “PERIOD MEASURMENT” mode.
5.6 In frequencies ratio mode perform the same measuring. The results show in table 5.3.
