2162i-4_Manuals 8/22/17 9:35 AM Page 18 2-Point Pythagoras Measurement Mode 2-Point Pythagoras measurement mode refers to a measurement mode based off the Pythagorean Theorem (A2 + B2 = C2). If you know 2 lengths (but not the third), this formula allows you to calculate a missing dimension of a triangle. The Laser Distance Meter uses this theorem to indirectly measure lengths that are otherwise not directly measureable, enhancing the utility of the tool.
2162i-4_Manuals 8/22/17 9:35 AM Page 19 4. Aim the Laser Distance Meter so that the laser dot is on the selected target to measure the length of the base (represented by “A” in the figure above). 5. Keep your position stable and press the button again. The “A” and “C” measurements will appear above the main screen. The indirect height will appear on the main screen (represented by “B” in the figure above). The laser will turn off. 6.
2162i-4_Manuals 8/22/17 9:35 AM Page 20 3. Keep your position stable and press the button. The “C” measurement will appear above the main display. 4. Aim the Laser Distance Meter so that the laser dot is on the selected target to measure the length “D” in the figure above. 5. Keep your position stable and press the button again. The “D” and “C” measurements will appear above the main display. 6.
62i-4_Manuals 8/22/17 9:35 AM Page 21 To use the 3-Point Partial Pythagoras measurement mode: 1. Press the button 5 times until the 3-Point Partial Pythagoras mode icon ( ) displays at the left of the LCD screen. 2. After selecting the desired unit of measure and reference position, aim the Laser Distance Meter so that the laser dot is on the selected target to measure the length “C” in the figure above. 3. Keep your position stable and press the button.
2162i-4_Manuals 8/22/17 9:35 AM Page 22 1-Point Pythagoras Measurement Mode This Laser Distance Meter is equipped with an angle sensor that can be used to both quickly check an angle (like a digital level) or to make more advanced 1-point Pythagoras calculations with only one measured length reference. The 1-Point Pythagoras mode uses mathematical relationships to calculate a distance that cannot otherwise be measured directly by measuring the angle of the tool and the length of a triangle hypotenuse.
2162i-4_Manuals 8/22/17 9:35 AM Page 23 Stake-out Measurement Mode The Stake-out mode is used when it is necessary to measure a repeating distance interval, such as when installing fence posting every 8 feet. It is important to have the volume enabled when using the stake-out mode, as the tool will beep to guide you to the correct distance. To use the stake-out mode: 1. Set your desired unit of measurement and measurement reference position, as described earlier in this manual. 2.
2162i-4_Manuals 8/22/17 9:35 AM Page 24 7. The Laser Distance Meter will begin beeping steadily, and 3 numbers will appear on the LCD screen. • The top number indicates the set stake-out distance that you have set. • The middle number indicates the number of stake-out points between the unit and the selected target. • The bottom number on the main display indicates the distance between the unit and the selected target. 8.
2162i-4_Manuals 8/22/17 9:35 AM Page 25 Digital Level Measurement Mode The Digital Level measurement mode provides an angle measurement. This laser distance meter can be used as a digital level to measure a vertical angle, shown above as “C.” There are many benefits to using this mode. Over short distances, it can be used for spot checking level of floors, countertops, etc. Over long distances, it can be used to check the angle of rafters or the relative height of two walls, etc.
2162i-4_Manuals 8/22/17 9:35 AM Page 26 Measurement Addition and Subtraction To add consecutive measurements, complete the following steps: 1. Complete your first measurement 2. Press the button. The first measurement will appear above the main display. 3. Complete your second measurement. The second measurement will appear above the main display, and the sum of the two measurements will appear in the main display. 4. Repeat step 3 above as necessary to add further measurements.
2162i-4_Manuals 8/22/17 9:35 AM Page 27 Calibrating the Angle Sensor This Laser Distance Meter is equipped with highly accurate digital angle sensors for using the 1-Point Pythagoras measurement mode. This sensor should be calibrated regularly for the most accurate results possible. To calibrate the angle sensor: 1. Find a fairly level horizontal surface such as a countertop, desk, wood floor, etc. The surface does not need to be perfectly level but should be within approximately 2° of level. 2.
2162i-4_Manuals 8/22/17 9:35 AM Page 28 10. Press the button. “CAL 3” will appear on the screen followed by “OK.” 11. Rotate the Laser Distance Meter 180 degrees so the laser beam is pointing towards you and the screen is facing the sky. 12. Press the button. “CAL 4” will appear on the screen followed by “OK.” 13. The Laser Distance Meter will power down, and calibration of the angle sensor will be complete.

2162i-4_Manuals 8/22/17 9:35 AM Page 31 9. Tips from the Pros • Take more than one measurement in situations where accuracy is critical. • Take 3-4 measurements from the same position to compare the consistency of each reading. • To accurately measure objects lacking an inside corner from the rear of the instrument, use a scrap piece of drywall or other flat material to extend the corner. Butt the Laser Distance Meter up to the material (as shown).
2162i-4_Manuals 8/22/17 9:35 AM Page 32 • Use 2-point or 3-point Pythagoras measurements when possible; they are generally more accurate than 1-point Pythagoras calculations. • Use the corner hook and corner extension to simplify measurements. • When working outside, a tripod will help stabilize the Laser Distance Meter for greater accuracy, particularly when longer measurements are needed.
