The LIDAR will return to the current operating mode (range or speed)
with the new reticle type.

Differential Distance Test

Note: The Differential Distance Test is an optional accuracy check
preferred by some jurisdictions. It is not a manufacturer required
test for daily required testing; however it is an additional test that
the operator may complete if they wish.

Differential Distance: LIDAR in Metric Units (km/h)

The (km/h) Differential Distance Test uses two fixed targets
separated by a precisely known distance. Using the LIDAR's range
function to determine the separation between the targets, the km/h
Differential Distance test provides a quick check of the LIDAR's ability
to measure the distance between two targets.
Use two flat targets, approximately 0.5m x 0.5m square, painted flat
white. Place the targets at precise distances from a "zero" point
where the LIDAR will be positioned. The targets should be set at
integer feet values from the LIDAR zero point and should be
approximately 10 metres apart. Recommended target distances are
20.0 metres and 30.0 metres from the LIDAR unit. Please note,
minimum range capability is 3 metres. Ensure the front end of the
LIDAR unit is positioned exactly at the zero point, using a tripod if
necessary.
