2.8 Pulselength
The pulselength in use is displayed at the upper left corner of the display.
Appropriate pulselengths are preset to individual range scales. Therefore, you
are not usually required to select them. If you are not satisfied with the current
pulselength setting, however, it is possible to change it for the 1.5 and 3 nm (sm)
ranges (3 and 6 kilometer ranges) as below. Generally, select a longer pulse for
longer detection range and shorter pulse for better range discrimination.
1.5 nm, 1.5 sm, 3 km: Short pulse, medium pulse
3 nm, 3 sm, 6 km: Middle pulse, long pulse
