What to do if my Nikon Measuring Instruments says 'Cannot measure'?

  Zachary GomezJul 27, 2025
  If your Nikon Measuring Instruments displays 'Cannot measure,' ensure that the laser emission and detector apertures are unobstructed and clean. Verify the target's shape and condition are suitable for reflecting the laser beam. Replacing the battery with a new one may also resolve the issue. It may be that a closer target, located inside the measurement range, cannot be measured.
