Hi Guys,

I've purchased a LMBR R2A chronograph but I could do with a little help with the set up of the unit as the product instruction are basic.

On the unit, one section in the set up shows a box with the saying "Distance Between Sensors Calibration" & the word "Gate".

Can you inform me please with the distance (in millimetres) I need to input.

Thank you in advance.

Mike
