I have a scale continuously inputting data into a serial port and it is being output into an excel spreadsheet. The issue I was having was that the scale would continuously output zeros into the spreadsheet until the actual weight was applied to the scale. I decided to write a macro that would delete the row if the input value was < 1. The issue I am having now is that I want to set this page up as a template and have the scale values go into a graph so I can plot the data. What I want to do is instead of the macro deleting the row, I would like for it to deny the input from the scale if the input is less than the value 1. Does anyone know of any way to do this? The data plots continuously and starts in column A row 1 and after every weight value the next data point is input in the same column next row.
