4. Location/Content of Warning Labels
Error Code Label
The LDM may return an error code during use, as
indicated by the display showing “ERR X,” where
“X” represents a number from 1 to 6.
The error codes are as follows:
1. Laser Range – The measurement distance is
outside the range listed in the specifications.
2. Weak Signal – The reflected laser signal is too
weak, either due to high ambient lighting at the
target or poor target reflectivity.
3. Display Range – The measurement distance,
area or volume exceeds the number of units the
display is capable of showing.
4. Low Battery – The batteries need to be replaced.
5. Temperature – The tool is either above the
maximum or below the minimum safe operating
temperature range.
6. Ambient Light – The tool is being used in too
bright of an environment to operate properly.

7. Operating Instructions
IM ORTANT: It is the responsibility of the user to ensure proper
maintenance of the Laser Distance Meter. Conduct periodic test
measurements to ensure the instrument is measuring accurately
and consistently. This is most important if the instrument has been
exposed to extreme temperatures or moisture. Always confirm
accuracy before and during important measurements. Keep the
Laser Distance Meter optic lens clean and inspect for damage.
The Laser Distance Meter is designed to withstand a drop from
3 feet (1 meter). If dropped from a higher distance, the tool’s
calibration may be affected and it should be tested for accuracy.
Power On/Off the Laser Distance Meter
Press either the button or the button to power on the
instrument.
Press and hold the button to power off the instrument.
Auto atic Shutoff
Laser will turn off after remaining idle for 2 minutes. Press the
button to re-enable the laser.
Unit will turn off after remaining idle for 5 minutes.
Notes:
• Use only alkaline batteries.
• Remove the batteries when storing the instrument for an extended
time (more than 3 months) to avoid damage to the tool should the
batteries deteriorate.

2. Inches in decimal format (e.g., 79.646 in)
3. Feet and inches in 1/32″(e.g., 6′7” 21/32)
4. Inches in 1/32″(e.g., 79″21/32)
5. Inches in 1/16″(e.g., 79″11/16)
6. Inches in 1/8″(e.g., 79″5/8)
7. Meters (e.g., 2.023 m)
To select a unit of measure before making a measurement, press the
button. The word “Unit” will display in the center of the LCD screen,
and the unit of measure will display at the bottom right of the LCD
screen. Continue to press the button to scroll through the different
units of measure. OR after taking a measurement, press the
button repeatedly to scroll through the various units of measurement.
Note: The screen will only display feet and meters in a decimal format
in Area or Volume modes.
Measure ent Reference Position
Note: Setting the measurement reference correctly is critical to
obtaining an accurate measurement, as it establishes the place where
a reading of zero (0) is located. If the wrong reference position is
selected, the measurement will be off by the length of the tool
(4.6″/ 4 3/5″).

2-Point Pythagoras Measure ent 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.
Typically, the Laser Distance Meter is used to measure a height shown
above as “B” when there is no target at the top surface at which to
aim the laser, such as a tall wall. The measurement can be taken by
standing back at some distance “A” and taking measurements of “C”
(on the side of the wall) and “A” (aimed level at the wall).
To use the 2-Point Pythagoras measurement mode:
1. Press the button 3 times until the 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 of the hypotenuse (represented by “C”
in the figure above and indicated by the flashing lines on the
LCD screen).
3. Keep your position stable and press the button. The “C”
measurement will appear above the main display.
1746i-4_Manuals 6/5/17 1:38 PM Page 18

©2017 Johnson Level & Tool 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. Press the button to clear the display and take your next
2-Point Pythagoras measurement.
3-Point Pythagoras Measure ent Mode
Similar to the 2-Point Pythagoras measurement
mode, the 3-Point Pythagoras measurement
mode indirectly measures lengths that are
otherwise not directly measureable.
Typically, the Laser Distance Meter is used to measure a height shown
above as “B” when there is no target at the top surface at which to
aim the laser, such as a tall wall, and it is not possible to aim the laser
from the ground level. The measurement can be taken by standing
back at some distance “A” and taking measurements of “C” and “D”
(on the side of the wall) and “A” (aimed level at the wall).
To use the 3-Point Pythagoras measurement mode:
1. Press the button 4 times until the 3-Point 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.
1746i-4_Manuals 6/5/17 1:38 PM Page 19

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. 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).
7. Keep your position stable and press the button again. The “A”
and “D” 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.
8. Press the button to clear the display and take your next
3-Point Pythagoras measurement.
3-Point Partial Pythagoras Measure ent Mode
Similar to the 2-Point and 3-Point Pythagoras
measurement mode, the 3-Point Partial
Pythagoras measurement mode indirectly
measures lengths that are otherwise not
directly measureable.
Typically, the Laser Distance Meter is used to measure a partial
height, shown above as “B”, when there is no target at the top
surface at which to aim the laser, such as a tall wall. The measurement
can be taken by standing back at some distance “A” and taking
measurements of “C” and “D” (on the side of the wall) and “A”
(aimed level at the wall).
