Operation Manual
Mutil Function Distance Meter With Laser
AM:T-316 multi fimction distance meter detennines the distance to the object through
electronic signals quickly and effective, the tool can display the result on the tow-row LCD with
back light. The tool with built-in computer chip has the ftmction of key indication and memory. It
can be used in continuous accumulative measurement, automatic areas and vohulle counting and
is an ideal tool for building and decoration industries (for example, land agent, upholstery
designer and craftsman, etc.)
The tool has the ftmction of laser orientation, it will send out a line of highlighted red laser
beam to make you aim at the object easily when using. The automatic temperature compensation
fimction of the tool can make the measwing result more accurately, and at the same time show the
current enviIomnent temperatme precisely.
AMT-316 distance meer is the Class II laser tool confonning to IEC285 intern ational saf ety rule.

OPERATION GUIDE
Battery installation
Open the battery compartment door on the back of the tool. and plug one 9 Volt block battery
onto the battery COlUlector and put the battery back to the compartment and close the dOOf.
Distance measurement
Make the induction hole of the tool face against the measured object (c.g the wall) and
keep the tool vertical to the measured object; make sure the poinl: of the level vial stands
between the two line of the level vial by adjusting the position of the mstrwnent.
Press the READ key to start the tool, the instnunent is ready to work.
Press the READ key again to get the measured distance and the laser beam indicates the
measured surf ace.
Keep pressing the READ key and move the tool to get the dynamical readings, and the
measured distance will be, displayed on upper portion of the screen;
Press the SET key and the READ key together to select the measuring unit as British
measmement or metric system. (original measuring unit : Metric measurement ).
Tips:
A.The measured object must be·nonnatively hard swface and not be blocked by any baniers;
B. Select a smooth hard surface with big area to measure for precise result;
C. If the measured surface is too small and iITegular or with soft mrface, chipboard can be
UBed on the surface of the measured object;
D. The tool cannot: measure through glasses;
E. The tool should be over 2 feet (60cm) away from the measured object when measuring;
F. To make sure accurate measmement, you should operate when temperature of the unit is
same with temperature of the circmnstance.
G. The distarice measurement should be counted from the end of the tool.
Addition (W/O using M memory)
Press key for measurement and the measmed value is displayed on upper portion of the
Press READ key to enter the addition mode, and the "+" icon will appear on the display and at
the same time, the result is displayed on the lower side of the display (press key again to cancel
the add operation);
Press READ key again for second time measurement, the measured value is displayed on upper
portion of the screen;

 Press E3 key again to display the stun on the lower portion of the screen;
• Repeat the steps above can continue accumulation.
Addition (using M memory)
Press the M key to save the fust: measured result, and the "M+" will appear on the display,
Press the READ key for new measurement;
Press the key to enter th e addition mode , and the "+" will appear on the display.
 Press the RM key to recall previous measurement for the addition (displayed on the bottom of the
display). and at the same time, the "M+" icon disappears and the stored memories will be
automatically eliminated;
Press +/=key, the sum is shown on the lower portion of the screen.
Area
Press SET key to enter area mode, and the will appear on the display for calculation of a room
area;
The length character "L" on the display will blink showing the length measurement you will be

OPERATION I NSTRUCTION
Inaccurate measurement may result from the following:
When the battery JUDS out: at this time, the icon will continuously appear on LCD to remind
you to replace the battery .
When the measmed distance is out of the specified range: the effective range is 2'~53' (0.6-
~16m).
When the calculated remit is out of the specified range: at this time. an error message "Err"
will be displayed on the lower line ofthe screen.
 When addition of different parameters (e.g. length plus area), the "+" will be ignored and the
screen will keep the same read as the unit was operated before.
 When another ultrasonic source or high frequency noise is nearby: leave or shut down the
noise resource when taking measurement.
When bani.ers appear between the tool and the measured surface.
When the measured surface is not smooth: the measured surface should be smooth, hard
and of homogeneity.
 When the measuring enviromnent is not good: the temperature and humidity will affect the
accuracy of measurement, and take measurement Wl.der enviromnent of no wind, and
temperature of the unit should be same 'With temperature of the circlDllStance, especially for
long distance measuring (between 40' to 53'/ 12m to 16m), the relative humidity should be above
480/0, and the size of measured surface should be at least 10ft. by 10ft/.3m by 3m.
When measuring. ultrasonic sensor aperture should straightly face to the measured surface.

Handle with care and do not let the tool dr!'P
down.
