Q1: Define Laser Level?
Ans:A laser level is a control tool consisting of a rotating laser beam projector that can be affixed to a tripod. It is used in surveying and construction for accurate measurements.
Q2: Define self-leveling.
Ans:Self-leveling is an automatic adjustment mechanism in laser levels that ensures accuracy by maintaining a level line of sight even if the instrument is slightly tilted.
Q3: Define IP rating.
Ans:IP (Ingress Protection) rating indicates the level of protection a device has against dust and water.
Q4: What is Amp-Hour Rating?
Ans:Amp-hour rating refers to the battery capacity, indicating how long a rechargeable battery will last before requiring a recharge.
Q5: What is Vast Operating Temperature?
Ans:Vast operating temperature refers to the temperature range within which the laser level can function accurately.
Q6: Name parts of Laser Level?
Ans:
The main parts of a laser level are:- ➔ Laser transmitter
- ➔ Laser receiver
- ➔ Control box
Q7: What are types of Laser level w.r.t Laser?

Q9: Describe accuracy of laser level.
Ans:Good laser levels are accurate within 1/16 of an inch per 100 feet.
Q10: Define Refraction?
Ans:Refraction is the phenomenon where light changes direction when it passes from one medium to another.
Q11: State benefits of laser level?
Ans:Laser levels help reduce labor, increase work speed, and improve measurement accuracy.
Q12: State Working of Laser level.
Ans:Laser levels work by generating a laser beam inside a protective housing, which is then projected onto a surface for reference.
Q13: What is difference between rotary and line laser level?
Ans:A rotary laser level projects a 360-degree beam, while a line laser level projects a straight line or crosshair.
Q14: What is laser beam orientation?
Ans:Laser beam orientation determines whether the laser projects in a horizontal, vertical, or 360-degree plane.
Q15: Write purpose of laser detector.
Ans:A laser detector helps in identifying laser beams in bright light conditions.
Q16: What is the purpose of laser transmitter?
Ans:The laser transmitter emits the laser beam used for leveling.
Q17: Define grade laser level.
Ans:A grade laser level is used to set precise slopes for construction projects.
Q18: What is the difference between Fixed and variable RPM?
Ans:Fixed RPM keeps a constant rotation speed, while variable RPM allows adjustments based on project needs.
Q19: Define RPM.
Ans:RPM stands for Rotations Per Minute, indicating the speed of rotation of the laser head.
Q20: What is rotary laser level?
Ans:A rotary laser level emits a continuous rotating laser beam to create a reference plane.
Q21: What is the difference between Line and dual beam laser level?
Ans:A line laser level emits a straight beam, while a dual-beam laser level projects both horizontal and vertical beams.
Q22: What is Line Laser level?
Ans:A line laser level projects a straight reference line onto a surface.
Q23: What is Dot laser level?
Ans:A dot laser level emits a single or multiple reference dots on a surface.
Q24: What is the purpose of eyepiece?
Ans:The eyepiece helps in focusing and aligning the laser beam.
Q25: Write two disadvantages of laser level.
Ans:
- ➔ Requires power source.
- ➔ Limited visibility in bright light without a detector.
