Setting the Range Offset

The Impulse has a feature that allows you to alter
the measuring point of the instrument. You may
want to move it closer to your target, or further
away, depending upon your circumstances. For
these instances, the Impulse provides the OFFSET
option, which adds a distance to the slope distance
measurement. Since slope distance is used to
calculate horizontal distance and vertical distance
in an Impulse 200, the range offset will also affect
these options.
For example, if you want to measure the distance
between two walls, you would put the rear plate of
the Impulse up against one wall and measure the
distance to the other wall. Without a range offset,
the distance measured would be slightly shorter
than the

actual distance, because the measuring point of the
instrument is at its center. Entering a range offset of
0.09 meters (.29 feet) would move the
measurement point back to the top of the battery
cap (which is against the wall) and would allow you
an accurate measurement from wall to wall.
Or, if the point you want to take a measurement
from is inconvenient to occupy, you could shoot the
distance to that point, then enter it as an offset that
will be figured into all subsequent measurements.
Range offsets up to ±999.99 may be entered. A
positive offset will lengthen your measurements, or
essentially move back your measurement point,
and a negative offset will shorten the measurement
by moving the measurement point closer to the
target.
