Model Number: UL110/W Brand Name: Eoutil Key Specifications/Special Features: UL110 Digital LCD Backlight Ultrasonic Distance MeasureThe UL110 ultrasonic estimator is a fast, convenient distance measuring tool. This tool allows contractors, realtors, homeowners and appraisers to make fast and easy estimates of distances, areas and volumes in rooms at work or home. Multiple measurements may be added to allow for overall measurements of greater than 60 feet.The UL110 ultrasonic estimator is intended for fast, convenient measurements with a high degree of accuracy. For precision measurements other measuring instruments should be used.Operating Instructions1.0 Battery Installation:The UL110 uses a 9 volt battery (not included) which is inserted in the bottom of the unit .To install the battery, remove the battery door form the button of the case and attach the battery connector onto the 9 volt battery. Reassemble the bottom to the case making sure it snaps into place. When the battery needs replacement the Low Battery indicator will appear in the LCD display.
2.0 Taking Measurements:
1. For consistent readings hold UL110 perpendicular to and pointed toward the surface being measured and press, release the “READ” button.
2. Press “ ” button to change the benchmark of measuring the distance front of or behind of the UL110.

3. To change the units of measurement press the “FT/M” button. The display will cyclethrough the units of measurement. The reading will be converted with each measurement change.

4. When repeating the reading make certain that the estimator is perpendicular to the surface, the distance is within its’ measuring range and that there are no obstructions in the way like desks, chairs, half walls or step ladders to reflect the sound waves.
Caution: Some types of surfaces such as curtains, padded walls, furniture or carpeting may absorb the ultrasonic sound waves instead of reflecting them, making readings difficult to take. These surfaces or irregular surfaces can also cause variations in readings. Try taking readings from different angles or positions to achieve consistent measurements.

5. When the light is dark, the LCD can be lighted by pressing “ ” button and also can be shut off.

6. The displayed reading will be shown for at least 30 seconds before the estimator shuts off.
