Q1: What does self leveling mean?
A: The FRE201, 202, 203 and 205 have a self levelling range of 5 degrees so once the instrument is in its self leveling range, the compensator makes sure that the beam is level.
Q2: Can I use a visible laser outdoors without a receiver?
A: A rotary laser will have to be used with a receiver outdoors in the sun. Sun light and visible laser beams tend to cancel each other out in sunlight which makes it impossible to see the rotating beam when outside. If you stop the rotating beam and shine it onto a shaded target, you can use it as a reference, but this is not that convenient.
Q3: What kind of working distance do your products have?
A: When paired with the receiver, most of the rotating lasers have a 200m to 500m working diameter. Line lasers have a reduced working range as they are designed to be used indoors only, and without the use of a detector.
Q4: How often should my laser be calibrated?
A: Lasers should be calibrated when they are not shooting their specified accuracy. We suggest checking calibration regularly, at least every 6 months, or immediately if the unit has been treated roughly.
Q5: Where can I get my laser serviced?
A: Almost any laser or survey instrument service center can calibrate our lasers. It is not recommended that the user do service or calibration work.
Q6: What kind of tripod do I need?
A: Our lasers fit tripods with a 5/8 x 11 coarse thread. Flat or domed head tripods.
Q7: Can the laser light hurt my eyes?
A: The maximum power output for any construction laser is less than 5 milliwatts. A milliwatt is one thousandth of a watt. No special precautions need be taken with an invisible beam laser. Visible beam lasers should be set so they are not flashing in anyone's eyes because the light is very bright and can be annoying. Having the beam flash in one's eyes occasionally will not do any damage, but will be irritating in the same fashion as a camera flash.
Q8: Can your laser be used for turning angles?
A: Some of our lasers have fixed plumb spots that provide a 90 degree reference relative to the rotating beam when the laser is in its vertical mode.
Q9: Can I use a receiver to pick up the plumb spot?
A: Electronic laser receivers are looking for a laser spot flashing across their photocells and will not respond to a stationary laser spot. That is why they can be set off by a flashing strobe or emergency beacon. Even if the receiver could pick up a stationary beam, the spot will be extremely difficult to find at any substantial distance from the laser.
Q10: What happens if my laser is rained upon?
A: Our FRE ## lasers are water and dust resistant. If the unit is caught in the rain, remove it from the weather and simply dry the laser off before it is stored. Most problems from water ingress occur when the laser is stored in its case when it is still wet. The laser will sweat in the case and moisture will work its way into the laser housing and can cause damage to the diode and circuits.
