This model of the Laser-Mini goniometer replaces the previous Goniometer Lite model and differs from it in appearance and design. For example, the new version does not have a flexible wire connection between the laser and the power board. Now both the board and the laser are rigidly mounted in a single ring structure. The sharpening measurement range is up to 88 degrees (total angle). Doing more just doesn't make sense, I haven't met any blades with a larger sharpening angle, and I haven't met any with an 80 degree angle either. The maximum possible blade width is 39 millimeters. The color can be: white, gray or black, depending on stock availability.
Two powerful magnets allow you to hold the blade on the angle gauge or the angle gauge itself on the blade, depending on the size of the latter. If the blade is large, it is even easier to hold it with your hand and the angle gauge will stay perfectly and securely on it.
The horizontal offset range is 10 mm. The scale rotation range is +-10 degrees. This is more than enough for any blade geometry and any reasonable thickness.
The better and more qualitatively you will perform approaches to the RK, the clearer and brighter will be the readings on the angle meter.
Everything is based on the principle of reflection, so the better (more mirror-like) your approach, the better.
The wheel itself is lubricated with silicone grease where it mates with the panel elements, which ensures smoothness and low force based on viscous friction. This results in a high smoothness of rotation and the impossibility of unstable movement and rattling. To protect the blade from scratches, I recommend putting pieces of duct tape or painter's tape over the magnets before measuring. Be sure to use two separate pieces of tape. One large piece will block the laser beam. To replace the battery, place the rotary dial in the center position and pry it with a thin object through the switch window. The next step is a matter of technique. Insert the new battery so that the "+" terminal is facing up. In case of a polarity error, nothing terrible will happen - the laser has protection against polarity reversal and will simply not turn on.
Do not forget to turn off the device after taking measurements - this will prevent unnecessary discharge of the battery, although it will not cause any damage to the laser.
The accuracy of the readings depends on the quality of the cutting edge wires.
