1-02 is set up to

In the mode of constant velocity, this parameter is used to select the display accuracy of the digital display
indicator, which is coordinately used with the function code of 0-05 to complete counting of the different
length. For instance: if 0-05 is set up as 1000 and 1-05 is set up as 0 then the length of the spinning yarn is
with the maximum value of 1000m and the display length is with the minimum value is 1 m; otherwise if
the 1-05 is set up as 1, then the length of the spinning yarn is with the maximum value of 10000m and the
display length is with the minimum value of 10m; else if the 1-05 is set up as 2 then the length of the
spinning yarn is with the maximum value of 100000m and the display length is with the minimum value of
100m. The users can set up them according to the actual situation.
