TECHNICAL SPECIFICATIONS Recommended Use Indoors or Outdoors Power supply Two “AAA” 1.5-volt batteries Angle Measuring Range 0º - 360º Optimum Operating Temperature 0º to 40º C (32º to 104º F) Accuracy of vials ±0.029º (level or plumb) Accuracy of digital display ±0.1º (level or plumb) Estimated battery life 12 hours with 2 AAA alkaline batteries OPERATION BATTERY INSTALLATION (Fig. 2) This multi-function digital level uses two “AAA” batteries (sold separately), to power the LCD module display. Fig. 2 NOTE: Always turn off the level before installing or replacing the batteries. 1. O pen the battery cover, located on the back of the level (Fig. 2). 2. Insert two new “AAA” alkaline batteries with the polarity (+/-) as indicated on the inside of the battery compartment. 3. Securely close the cover. LCD DISPLAY AND BUTTON FUNCTIONS LCD screen icons Up/Down Indicator: • The zero line (0º) indicates the “true level.” • The second line, appearing either above or below the 0° line, indicates the level’s position relative to “true level.” • The arrow indicates the direction in which the level needs to be moved to achieve “true level.” 48295 Manual_Revised_07-0620 Page 5 attery Power Icon - Indicates the amount of battery power in the unit. B Replace batteries when the black power bar disappears. Sound Icon - This icon appears on the screen when the sound function is activated. Hold Icon: Indicates that the displayed measurement is frozen. Button Functions Button (On/Off, Sound) Press the button to turn the LCD display screen on. • When the LCD screen first comes on, the ambient temperature is displayed in Fahrenheit for approximately 2 seconds to help the user determine whether the level is being used in the optimum temperature range (32º to 104º F). • The current angle of the level is then displayed on the LCD screen, and a line representing that angle is shown either above or below the line that indicates the position of true level (Fig. 3). • Briefly press the button once more to activate the sound, which will beep when the level is positioned at 0°, 45°, 90°, and last hold angle to true level. • Briefly press the button a third time to turn off the sound. Additional brief presses on the button will turn the sound function on and off. • An arrow on the display indicates the direction in which the level needs to be moved to reach true level. • True level is indicated when the angle line and the level line in the display are together, and the angle shows 0 (Fig. 4). • Turn off the level by pressing the button and holding it in for approximately 3 seconds. • The level will shut itself off when it has not been used for 5 minutes. 48295 Manual_Revised_07-0620 Fig. 3 Fig. 4 Page 6 Zero Button - Absolute/relative angle conversion button for comparison of two work surface angles. 1. W hen the level is first turned on, it is in the absolute angle mode and displays the angle from true level. 2. T ake a measurement of the first work surface; the LCD screen indicates the angle between that surface and true level. 3. P ress the zero button for the relative angle mode, and the level will set the first angle to zero. 4. M ove the digital level to the second work surface, and the LCD screen indicates the relative angle between the first and second surfaces. 5. To return to absolute angle again, turn the power button off and back on. Convert Button – Converts the angle display on the LCD screen among 3 different units. • Press the button to proceed through the display units: Degrees (º), Slope (%), and Pitch (in/ft). • Pitch readings are in increments of 1/8-in. per ft. Plus and minus signs indicate whether the pitch is slightly more (+) or slightly less (-) than the pitch that is shown on the display. Hold Button To hold the information of the current reading, press the Hold button to freeze the displayed reading; press it again to return to measuring mode. TO USE THE LEVEL FOR HORIZONTAL AND PLUMB MEASUREMENTS Horizontal and Plumb measurements can be made with both the bubble vial and the LCD display features Horizontal • Use the level on horizontal surfaces to determine when they are level. Place the level against the horizontal surface. The surface will be at true level when the bubble is positioned exactly between the marks on the level vial. • The LCD display represents the surface you are measuring as a line, either above or below the 0, or “true level,” line, with an arrow showing whether the surface should be raised or lowered in order to be level. The digital display shows the degree to which the surface is “out of level.” If the sound is turned is on, the level will beep when true level, or 0°, is reached. 48295 Manual_Revised_07-0620 Page 7 PLUMB (Fig. 5) Fig. 5 • T o find the plumb of a work surface, place the digital level against the vertical surface with the plumb bubble vial at the top. The surface will be at true plumb when the bubble is positioned exactly between the marks on the vial. • T he LCD display will show the actual angle of the surface. 90° is “plumb;” a beep will sound at 90°, if the sound function is turned on. TO USE THE LEVEL FOR ANGLE MEASUREMENTS Pitch (Fig. 6) • The digital level can be used to measure pitch, for example, the pitch of a roof. • Pitch is measured in inches of rise per foot of run. • The pitch will be read as inches (in 1/8-in. increments) per foot, with a + or a - sign to indicate that the pitch is slightly above or below the displayed measurement. Fig. 6 Push the convert button to change the display to Pitch mode (in/ft). Angle (Fig. 7) Fig. 7 The digital level measures any angle in degrees, with up to 0.1° accuracy. If the sound button is turned on, the level will beep at the 0°, 45°, 90°, and last hold angle. Push the convert button to change the display to Angle mode ( º). Fig. 8 Slope (Fig. 8) The digital level measures the percent slope of a surface. This is useful when laying pipe for proper drainage. When the display is in the slope mode, it will measure the surface in percent, with exact level a 48295 Manual_Revised_07-0620 Page 8 0.0%. If the sound is turned on, the level will beep at 0.0% and 100%. Push the convert button to change the display to Slope mode (%). ABSOLUTE AND RELATIVE ANGLE MEASUREMENTS Absolute angle measurement 1. Place the digital level on a working surface with the base flat against the surface. 2. T he display indicates the absolute angle between “true level” and the working surface. The zero line indicates the level position, and the arrow indicates the orientation of the working surface: either above or below true level. 3. T button. The level will beep o activate the sound, briefly press the when the level is at 0° (level), 45°, 90° (plumb), and last hold angle. 4. P ress the Hold button to freeze the display reading. To take a new measurement, press the hold button again to return to measurement mode. Relative angle measurement The relative angle mode allows you to measure the angle of difference between 2 different surfaces. 1. Place the digital level on Surface 1. 2. The LCD screen indicates the absolute angle between true level and Surface 1. 3. P ress the ZERO button to activate the relative-angle measurement mode. The current angle will be considered to be 0.0° and the display will read 0.0°. 4 P lace the digital level on Surface 2, and the relative angle between Surface 1 and Surface 2 will be displayed. The zero line indicates the Surface 1 position, and the arrow indicates the orientation of Surface 2, either above or below Surface 1. 5. A t this point you can change the display units for the measured angle from degrees (°), to pitch (inch/foot), or slope (%) by pressing the convert button. 48295 Manual_Revised_07-0620 Page 9 MAINTENANCE This digital level has been designed to be a low-maintenance tool. However, in order to maintain its performance, follow these steps: 1. H ANDLE the tool with care. Treat it as a precision optical device, such as a camera or binoculars. 2. A VOID exposing the tool to shock, continuous vibration, or extreme hot or cold temperatures. 3. S TORE the tool indoors and in a safe place. 4. T he Level is designed to be weather resistant and construction-site tough. If the level is splashed with mortar or other construction-site residue, simply wipe it clean with a damp cloth. 5. D O NOT immerse the level in water. 6. Aluminum surfaces can be cleaned with a non-abrasive powder. 7. R EMOVE the batteries from the tool if it is not going to be used for an extended period. 8. D O NOT attempt to take the level apart. TROUBLESHOOTING PROBLEM The LCD screen will not turn on. CAUSE SOLUTION • Batteries are installed incorrectly. • Reinstall batteries with correct polarity. • Battery voltage is low. • Replace with new batteries. • The LCD screen is damaged. • Take tool to Sears Service Center. 48295 Manual_Revised_07-0620 Page 10 Notes 48295 Manual_Revised_07-0620 Page 11 Get it fixed, at your home or ours!
