Frequency is divided into four ranges, automatic switching: 1. XXX (no decimal point): the smallest unit is 1Hz, ranging from 1Hz - 999Hz; 2. X.XX (decimal point in 100 bits): the smallest unit is 0.01 Khz, ranging from 1.00Khz - 9.99Khz. 3. XX.X (decimal point in ten places): the smallest unit is 0.1Khz; the range of values is 10.0KHz-99.9KHz. 4. X.X.X (decimal point in 10 and 100 bits): the smallest unit is 1Khz; the range of values is 1KHz-150KHz
