Hello I have the pros pro tomcat Mt-400, it is yes a constant pull machine, I have to wait after the beep signal until I disconnect since the numbers are dynamic. Say if I set for example 25kg, I release the clamp the number fluctuates. I make the clamp on and the number continues to fluctuate. Do I now wait until the desired 25kg are displayed and release Constant pull at the perfect moment or can I simply ignore the number fluctuations?
