TO
INSTALL BATTERY (See Figure 3)
NOTE: This tool operates on one 9-volt battery
(not included).
1. Open battery compartment door on the back of tool
2. Plug 9-vott battery into the battery conductor,
3. Close battery compartment door_
IMPORTANT NOTE: When the battery is low, the low battery
[_ will be continuously displayed on the upper left side
of the LCD display screen,
HOWTO USE LASER GUIDED MEASURING TOOL
Place the bottom of the tool at the point from which the
measurement is to begin (such as a wall or floor),
The built-in level vials will help you to align the tool at 90°.,
The ultrasonic signal is projected in circular
waves (see Fig. 4).
For tong distance measuring, between 40 to 50 feet
(12 to t5 meters), the target area should not be smaller
than 10 x 10 feet (3 x 3 meters)
IMPORTANT NOTE:

1. In order to get the most accurate result, make sure the ultrasonic wave is perpendicular
to the target,,
2. The target area must be a hard regular surface with no objects or obstacles in the measured field
3, Place a piece of cardboard on front of the target if the measured target is small, irregularor soft_,
4. This tool cannot be used to measure through glass, even though the laser beam can pass through
5. All measurements are calculated from the bottom of your tool (as shown in Fig, 4)
HOWTO READYOUR LASER GUIDED MEASURINGTOOL
1. Press the power key and the LCD display screen will show the temperature in degrees
Fahrenheit,
2. Point the tool perpendicularly at the target and get the measurement by pressing the
"Read" key,
3o Each measurement erases the previous one.
4. The measurement was unsuccessful if "Err" appears on the LCD display screen
5_When "Err" appears on the display screen, press "Read" key or re-start the tool to measure
again, making sure to avoid the following conditions:
,, The target surface does not provide a good reflection for the ultrasonic measuring
signal (e i.,it is a soft, irregular surface such as thick carpet, curtains, or irregular
wallpaper, etc)
oThe distance measured is out of the specified measuring range (2 to 50 feet),,
o There are obstructions within the specified measuring range°
=The tool is not perpendicular to the target
6. The tool automatically turns off, if not used for 30 seconds,
7o Measurements can be ready easily even in dark conditions due to the back-lit LCD screen.
IMPORTANT NOTE: in order to get accurate measurements, always be sure to point the tool
perpendicularly to the target before starting any measurements,
