Answers
A1: A, B & D
A2: True
A3: False, rotary laser levels are recommended for outside and inside applications
A4: True, exterior laser levels typically rotate very quickly to send as many signals to the detector/receiver as possible.
A5: No, you will not be able to see a rotary laser level beam outside. A detector/receiver must used to detect the rotating laser level beam.
A6: A, C & D
A7: False, one of the primary benefits of using a rotating laser level is that it only takes one person to operate.
A8: E - All of the above
A9: False, interior laser levels have green or red laser level beams only.
A10: D, Green beam laser levels are 400% brighter to the human eye then red beam lasers.
A11: True, the slower the rotation speed the more visible the beam is. The faster the rotation speed the more of a chalk line effect can be seen.
A12: Using the scan mode feature on an interior laser level concentrates the 360° beam to a specific 30° or 60° area. By narrowing the angle of the laser level beam it make the laser level beam even more visible to the human eye.
A13: C & E, A ceiling mount that is designed to hold the laser level on perimeter wall angle when installing an acoustical ceiling
A laser level target with reflective tape on the back also helps the operator see the laser level beam.
A14: E - All of the above
A15: Yes, versatile laser levels with variable speed can be used outside at their fastest rotation speed with a detector and at a slower speed inside so the operator can see the beam.
A16: 1. Faster set up. Using a self leveling laser level is much quicker to set up on a tripod, level and begin working. A manually leveled laser level requires the operator to adjust the leveling screws to level the laser. 2. An out of level indicator. If a self leveling laser level is moved out of its self leveling range, an audible and visual alert signal will activate. There is no out of level indicator on manually leveled lasers.
A17: True, a two dot laser level is designed to give the operator a plumb point between floor and ceiling. A three dot laser level is designed to give the operator plumb and level. A five dot laser level provides the operator plumb, level and right angles.
A18: Yes, because the laser level beam is concentrated into a dot, a dot laser level beam can be seen outside in the daylight.
A19: E - All of the above
A20: True - some laser levels are designed to project a vertical and horizontal line simultaneously while other line laser levels are designed to project one, two, three or four lines individually.
A21: No, a line laser level beam can not be seen outside in the daylight. In order to use a line laser level outside in the daylight, the line laser level must have a "pulse" feature and be used with a line laser level detector/receiver.
A22: B & E, A line laser level detector/receiver when the line laser level is being used outside. The line laser level must have a "pulse" feature. Light Duty Tripod - Light Duty Tripod. The operator puts the laser level on the platform and sets the platform and laser level beam to any desired height.
A23: E - All of the above
A24: True
A25: False, it takes two people to establish elevations using an optical instrument. One person to look through the instrument and take the elevation reading off the grade rod and one person to hold the grade rod at the desired location
A26: E - All of the above
A27: A & D, A tripod to hold the optical instrument. A grade rod to measure changes in elevation.
