The frequency of the clock used as reference in scaler channel 13 has been measured precisely.
In contrast to what was expected (1.5MHz precisely), it is:

Be careful. The voltage value on user interface is 10 times of real value. e.g. if the real value is 32V, the voltage value on UI has to be 320V.
