XERO C1 Pro Owner’s Manual

Starting a Bow Session

NOTICE

Always ensure that you position the chronograph so that it is not directly exposed to ejecting cartridge cases, muzzle blast, or other hazards that may damage the chronograph.

When you use the chronograph for archery, you should use a target that is at least 4 meters or 4 yards away from you.

  1. Select NEW SESSION > BOW.
  2. If you have enabled the PROJECTILE WEIGHT ENTRY setting (Pro Settings), select an option:
    • To calculate the kinetic energy and power factor of your arrow, select YES, and enter the weight of your arrow.
    • To continue without calculating kinetic energy and power factor, select SKIP.
  3. If necessary, observe the alignment diagram, and press OK to continue.
  4. Point the chronograph at the target with the screen facing you.
  5. Hold the bow over the chronograph so the arrow is 15 to 35 cm (5 to 15 in.) above the chronograph .

The device detects shots and displays measurements automatically as you shoot. The measured velocity is the speed of the arrow as it passes over the chronograph.
