4.3.1. Frequency measure with C300 calibrator as a reference source (example for number of measuring
impulses mode and 200 measuring impulses)
4.3.2. Frequency measure with external reference (example for measuring time mode and 15s measuring
time for both S0 inputs – first S0 input measure a frequency of electricity meter, second S0 input
measure a frequency of external reference)
