Operation
This tool will quickly and accurately measure distances. It will accumulate several
measurements in memory, and will perform area and volume computations.
In addition to distance measurements, area computations have many uses including
estimating wall covering or paint requirements, room sizes, etc. Volume computations
are useful in planning HVAC, heating and cooling requirements, etc.
Measurements are made using an ultrasonic beam which is targeted with a laser
beam. The laser beam will help you see the measurement which is actually made
with an invisible ultrasonic beam.
Since local conditions, such as temperature, vibration, humidity, etc. may affect the
measurement, you can take several dynamic readings to determine the most
accurate distance.
For the following instructions, please refer to the diagrams on page 4 to
identify components and displays.
Distance Measurement:
1. Point the Ultrasonic Sensor Aperture (1) in the direction of the distance to be measured.
2. Press the READ Key (10) to start the tool. NOTE that the laser light will
indicate the place measured. Press the READ Key (10) several times to
determine an accurate reading. The measured distance will be displayed on
the upper line of the Display Screen.
3. By pressing the FT/M Key (6), you can alternate the reading between SAE
and Metric readings.
NOTES:
A. The measured object must not be blocked by any barriers.
B. For precise results, use a large smooth surface for measurements.
C. If the measured surface is soft or irregular, you may place a hard item,
such as a piece of board in front to provide an accurate reflective surface.
D. Measurements cannot be made through glass.
E. The measured distance should be greater than 2 feet and less than 50’.
F. The measured distance is from the bottom of the tool (reference point 11,
page 4).

Screen. To replace the battery, open the Battery Compartment on the back of
the tool. Remove the old battery and install a fresh new 9VDC battery. Be sure
to match the + and - polarity of the battery with the markings in the Battery
Compartment.
2. Measured distance is our of range. The effective range is 2’ to 50’. If the
measured distance is less or greater than this range, an “err” message will
appear in line one of the Display Screen.
SKU 93619 For technical questions please call 1-800-444-3353. Page 8

3. Calculated result is out of range. If the calculated result is greater than the
values listed in the Specifications chart on page 2, an “err” message will
appear in the second line of the Display Screen.
4. Addition of different parameters. For example if length is attempted to be
added to area, the “+” operation will be ignored, and an “err” message will be
displayed in the lower line of the display.
5. Interference from another ultrasonic or high volume source. Turn off the
tool, and wait for the interference to stop before resuming work.
6. Barriers between the tool and the item to be measured. The ultrasonic
beam must have an unobstructed path to the object to make a precise
measurement.
7. Measured surface not smooth. To obtain an accurate reading, the measured
surface must be relatively hard, smooth, and of one material. You may have to
provide a smooth hard reflector (such as a board or card) in front of the target
surface to obtain a measurement.
8. Temperature, humidity or wind may interfere. If the environment has high
humidity, extreme temperature or high wind, the ultrasonic beam may not
function accurately, especially over long distances. Avoid high wind, and
observe the temperature and humidity ranges suggested in the specification
chart on page 2.
9. Measurement not aligned. When measuring, the ultrasonic beam must
strike the measured surface directly, not at an angle.
