Answer
- Calibration
- Calibrate the laser outside where you are working:
- If you move to a new job site
- If the temperature changes drastically
- If the batteries get changed or need to be changed
- If the laser gets dropped
- If the azimuth indicator “AZ” is blinking
- Calibrate the laser with the mounting brackets attached (if applicable)
- Check to see if the tilt sensor is aligned properly
- Shot the laser while horizontal and the inclination should be very close to zero. If the values are a degree or more off, you should recalibrate the tilt sensor
- Setup
- Mount the laser > 18in from the data collector
- Mount the laser > 6in from an antenna
- Data Collection
- Get as close as possible to the object you are trying to offset
- Within 200 ft for sub-meter
- Make sure you have a clear line of site to the feature you are shooting
- The following objects may potentially affect the TruPulse 360’s performance and should be avoided;
- Your Environment (20’ separation)
- Vehicle
- Building
- Powerlines
- Etc
- Your Person
- Batteries
- Data collectors or computers
- Cell phones
- Watch
- Clip board
- Hatchets
- Homemade Yokes
- Magnetic antenna mounts
- Tripods
- Nails
- Pin flags
- Portable radios
- Steel-rimmed eyeglasses or spring hinge
- Tripod tribrachs
- Simple Field Tests to Determine Magnetic Interference
- Target / Step Test
- Choose a target, shoot it and note the azimuth
- Step along the sight line and shoot the same target again
- 180° Target Test
- Aim and shoot to a target, note the azimuth and mark you current location
- Move to the target and aim back to your original occupied point.
