this function is not applied in this machine
When you check the water level, the first digit is a 0 which means 2.
A display indicating 041 is a water level frequency of 241 multiplied by 0.1 KHz , for
an actual frequency of 24.1 KHz.
Under 200 rpm: The display indicates the rpm. (Under 200 rpm)
Over 200 rpm: The display indicates the rpm. (x 10 rpm)
So, for example a display indicating 050 : rpm of 050 x 10 rpm = 500rpm
