Ungrouping Sensors on the Impulse 200
The Impulse 200 takes only those readings
necessary to satisfy the current option. This makes
it possible to "ungroup" the sensors by taking a
separate reading with each sensor. Then by
scrolling to another option, the instrument will
combine those readings to calculate other related
measurements.
For example, when slope distance (SD) is
measured, only the range sensor is activated, and
when inclination (INC) is measured, only the tilt
sensor is activated.

Now, a horizontal distance (HD) measurement is
calculated from SD, which is read by the range
sensor, and INC, which is read by the tilt sensor.
The straight-forward way of measuring HD is to
simply shoot when the HD indicator is showing, so
the instrument calculates everything at once.
But suppose, for example, that an obstruction or
other unusual situation prevents you from taking a
reliable reading with one or the other sensor. In that
case, you can shoot an SD measurement,
reposition the instrument slightly, and then take an
INC measurement. Then scroll to HD, and you will
see that the instrument has calculated a horizontal
distance from your two separate sensor readings.
