reset to zero. Basic and height measurements are
cleared, and only a cumulative distance total will be
converted from the current measurement units to
the newly selected units.

Percent Slope

Percent slope (indicated by "%") is a calculation
equal to 100 times the tangent of the inclination
angle. It is a variant way of expressing the
inclination and is available on the Impulse 200 only.
An inclination angle of 5 degrees, for example, is
equal to a slope of about 8.75 percent. An
inclination of 90 degrees will generate the display
overflow error "doF," and inclinations that exceed
±90 degrees will generate error "E05."

option, and an inclination measurement is
displayed, that measurement is a percent slope, not
an inclination angle. The % indicator shows to
remind you. (Note, however, that you can get
percent slopes only in the basic measurement
displays, never in the Height measurement
displays. Note also that the instrument never
downloads a percent slope. It always downloads
the inclination angle. The D/G indicator indicates
the units to be used in the download message.)

Range Resolution

A range value may have 1 or 2 decimal places
depending on how many will fit in the six digit
display. Most measurements will be resolved to two
decimal places, but values larger than 9999.99 and
smaller than -999.99 will only show one decimal
place.
