19、.So when the input is 37.5mV,the display will be 500 (1000-0)*(37.5/(75-0).When the low point of the input is not 0:For example: The input signal is 4-20mA,and the display needs to be 0-60.00Hz,then the chart of the relationship will be as follows:Setting: H: 6000,fiWe can get L according to the cha
20、rt: (In (H)-In (L)/In (L) = (Dis (H)-Dis (L)/ (Dis (L)-L). So L= 0 - (6000-0) * 4 / (20 - 4)= -1500.A.P:2; so when the input is 4 mA,the display will be (6000-0) * (4/20) + (-1500) = 0Hz5.3.6 How to modify the communication address,communication baud rate and communication modeSingle phase:IWtt llod
