Delta Distance Test
Your UltraLyte LR B may not include the Delta Distance
Test. It is a factory-defined option that is set when the
instrument is shipped.
The Delta Distance Test requires two targets.
If your UltraLyte LR B measures Miles per Hour and Feet
,
LTI recommends that the first target should be 150 feet from the
shooting mark, and the second should be 175 feet from the mark.
See Figure 28(A). If there is not enough space available, that specific
distance is not crucial. However, the distance between the target and
the shooting mark must be a multiple of 1 foot, not a fraction of a foot.
If your UltraLyte measures Kilometers per Hour and meters
,
LTI recommends that the first target should be 45 meters from the
shooting mark, and the second should be 55 meters from the mark.
See Figure 28 (B). If there is not enough space available, that specific
distance is not crucial. However, the distance between the target and
the shooting mark must be a multiple of 1 meter; not a fraction of a
meter
Refer to the instructions below and Figure 28 as a guide for positioning
the targets and the shooting mark.
1. Install the farther target.
2. Measure 175 feet (or 55 meters) to the shooting mark and
mark the shooting spot.
3. Measure from the shooting mark 150 feet (or 45 meters) to
the second target.
4. Mark that spot and install that target.
