Measurement Modifiers
Measurement modifiers are options that can help you select or eliminate targets and help you take the most
accurate measurements possible. The measurement modifiers are:
Indicator Function
Explanation
GATE Measurement
Gate
Sets up a measurement “gate” or “window.” When gates are set, the
Impulse will only measure targets that are at or beyond the window’s
minimum distance, and at or within the window’s maximum distance
G - Gate option is on
S - Short gate is set, increasing the minimum measuring distance
L - Long gate is set, decreasing the maximum measuring distance
OFFSET
Range Offset
Adds or subtracts a distance from the slope distance measurement
PIVOT Height
Pivot
Offset
(Impulse 200 only) The difference between the measuring point of the
instrument and the point at which it pivots to take top and base angles
during hand-held height measurements
FILTER
Filter Mode
Reduces the sensitivity of the laser sensor to only detect light returned
from a reflector
