I Laser Rangefinders
B Tip
C
You can pressfto toggle between displaying slope
distance/inclination and horizontal/vertical distance.
This form shows the most recent offset received from the laser
rangefinder. If you take further readings using the rangefinder, these
appear on the status form, replacing the previous reading.
You can take a reading with the Criterion rangefinder and transmit it to
the Asset Surveyor software as follows:
1. Follow the instruction sequence described earlier in this chapter
to set the Criterion into SURVEY mode.
2. Aim at a suitable target point at least 7 m (20 ft) away.
3. Keeping a steady hold on the instrument, aim through its scope
and carefully pull the trigger, releasing it when you hear the
laser acquiring lock on the target.
– Readings from the Criterion’s compass and inclinometer are
continually averaged as long as you hold the trigger. To maximize the
accuracy of these measurements, pull and hold the trigger for up to 10
seconds.
4. Hold the instrument completely still and on target until all
sounds end.
The distance and azimuth to the target point are displayed on
the Criterion’s LCD, for example:
HD: 40.89 M
AZ: 330.3 DEG
Warning – You can press the ↑ and ↓ arrow buttons to view other values
such as the vertical angle and slope distance. You must return to the
screen showing HD and AZ before performing step 5 (below), otherwise
the Criterion does not send the full measurement details to the Asset
Surveyor software.
