Ultrasonic Distance Meter
with Laser Tape

Using the specialty of the ultrasonic spreading in
the air, emit ultrasonic beam to measure the real
distance form a point to surface. Accomplish the
measure of beeline, are, volume in the mean time.
Accumulations of sameness property data,
storage, resume. Conversion unit between feet,
inch and metric system. LCD displayer, soft push
electric conduction rubber keyboard, laser
indicator. LCD displays all when replacing battery.

CAUTION
DO NOT stares directly at the laser beam.
DO NOT projects the laser beam directly into the
eyes of others.
DO NOT set up the tool at eye level or operates
the tool on or near a reflective surface, as the
laser beam could be projected into your eyes or
the eyes of others.
READ PRIOR TO OPERATION
Inaccurate measurement may result from the
following:
1) When the measured distance is out of the

specified range (2’ to 50’/ 0.6 to 15m).

2) When the battery runs out.
3) When another ultrasonic source is nearby.
4) When the unit is not held perpendicularly to the

target.

5) When there don’t have a good ultrasonic

reflecting interface for the object.

An error message “Err” will be displayed under
the following conditions:
1) When the measured distance is out of

specified range(2’ to 50’/ 0.6 to 15m).

2) When the target surface does not provide good

reflection for ultrasonic pulse (i.e. soft and
surface such as thick carpet, curtain or
irregular wall paper etc).

FEATURE

OPERATION INSTRUCTION
(Length, area, volume measurement)
1) Length
Length measurement and addition (w/o using
MEM)
*Press “READ” for measurement
*Press "+/=" to enter the addition mode, A “+” icon
will appear on LCD, the sum will appear on
bottom of LCD.
*Press and hold “READ” again for second
measurement.
*Press "+/=" again the sum is shown on bottom of
LCD.
*Follow above steps for multi-length
accumulation.
*Renew another accumulation by press"+/="
twice to eliminate data display on LCD.
Length measurement and addition (using MEM)
*Press “MEM INPUT” to save the desired
measurement for addition.
*Press “READ” for new measurement.
*After getting the new measurement, press"+/="
to enter the addition mode, A “+” icon will appear
on LCD, the sum will appear on bottom of LCD.
*Press “MEM RECALL” to recall previous
measurement for the addition. The ”MEM” icon
will disappear and the stored memory will be
automatically cleared.
*Press "+/=" again the sum is shown on bottom of
LCD.

accumulation.
* Renew another accumulation by press"+/="
twice to eliminate data display on LCD, but not
the stored memory
2) Area
Area computation
*Press “

“ to enter area mode for

calculation of a room area.
*Step 1:”L” will blink showing which measurement
you will be taking.
Press ”READ” to take “L” measurement that is
display on upper portion of screen.
*Step 2:”W” will blink showing which

measurement you will be taking.
*Then the area (LXW) is automatically displayed
on the lower portion of the screen.
*Press the “READ” key again will toggle back and
forth between the “L” and “W” measurements.
*To start another area mode, press”
