Safety regulations
Please read the safety regulations and operation guide carefully before operating.
Please read all of the operational guide and safety regulations in this manual before operation . Improper
operation without complying with instructions gi en in this manual could cause damage to the de ice, incorrect
measurement results or bodily injury to the user.
Do not disassemble or attempt repair in any ways. It is forbidden to do any illegal modifications or performance
changes for laser emitters. Please keep it out of reach of children and a oid use by any irrele ant personnel.
It is strictly prohibited to shoot eyes or other parts of body with the laser; also a oid shooting laser at any
objects' with strong reflecti e surfaces.
Due to electromagnetic radiation interference to other equipment and de ices, please don't use the meter in a
plane or around medical equipment, and don't use it in inflammable, explosi e en ironments.
Discarded batteries or meter de ices should not be processed just like household garbage, please handle them in
line with related law and regulations.
Any quality issues or any questions on the meter, please contact Kogan.

Installation for batteries, display screen and keyboard for batteries, display screen and keyboard
Installation and replacement of battery
• Open the battery door on the back of device, and place battery according to correct polarity, then close the battery
door.
• Only 1.5 V AAA alkaline batteries are to be applied to the meter.
• If device is not being used for a long time, please take out the batteries to avoid battery corrosion to meter body.

nstrument/Menu Setting
Start and shut off the meter
hen off, press key, instrument and laser get starting simultaneously and into stand by for measurement.
hen already on, hold down key for 3 seconds to turn the device off. The instrument will automatically shut off if
there has been no operation for 150 seconds.
Unit setting
Press the key to reset current unit of measurement, the machine default unit is: 0.000m
Backlight Setting
Hold down the key to turn the backlight on and off.
Optional units are available as below:
Length Area Volume
0.000 m 0.000 m20.000m3
0.00 m 0.00 m20.00 m3
0.0 in 0.00 ft20.00 ft3
0.00 ft 0.00 ft20.00 ft3
Measurement benchmark setting
Press key to enter into setting of switching between front benchmark and end benchmark.
System usually takes end benchmark as default.
Measurement for distance, area, olume;
Pythagorean proposition indirect measurement, adding & subtracting
Single Measurement:
Press key under measuring mode, the laser will be emitted, measuring location.
Re-press key for single measurement of distance , then the measured results will show on main display.
Continuous Measurement:
Long press key under measuring mode to enter into continuous measurement state, and maximum and minimum
measurement results in the process of continuous measurement will display on the screen.
The main display screen indicates the measured result, press key to exit continuous measurement state.
Area Measurement:
Press key and you will see on the display screen, that is Rectangle with one edge flashing. Complete the
following operations according to screen tips:
Press key to measure the first edge(length).
Press key to measure the second edge(width).
Area will be calculated automatically by the meter, and the results showed on main display screen.
Press key to remove previous measured result and get ready for the next measurement.
Volumetric Measurement:
Double press key and you will see , on the display screen, that is cube with one edge flashing. Complete the
following operations according to tips:
Press key to measure the first edge(length).
Press key to measure the second edge(width).
Press key to measure the third edge(height).
Volume will be calculated automatically by the meter, and the results showed on main display screen.
Press key to remove previous measured result and get ready for the next measurement.

Pythagorean proposition indirect measurement:
There are three kinds of pre-designed measuring modes to get unilateral distance of triangle by ways of Pythagorean
proposition. This is convenient for users to do indirect measuring in certain complex environments. Press key to
make mode selection:
1) Press key and you will see on the display screen, that is a triangle with hypotenuse flashing.
Press key to firstly measure the length (a) of dotted line hypotenuse according to screen prompt
Press key to measure the length(b) of the dotted line right side
Length (x) of the solid line right side will be calculated automatically by the meter.
2) Double press key and you will see on the display screen, that is a triangle with vertical leg flashing.
Press key to firstly measure the length (a) of dotted line right side according to screen prompt
Press key to measure the length (b) of the other dotted line right side
Length(x) of the solid line hypotenuse will be calculated automatically by the meter.
3) Press key 3 times and you will see on the display screen, that is a triangle with hypotenuse flashing.
Press key to firstly measure the length (a) of dotted line hypotenuse according to screen prompt
Press key to measure the length(b) of dotted line hypotenuse (shown as in the figure)
Press key to measure the length(c)of another dotted line hypotenuse (shown as in the figure)
Length (x) of the solid line right side will be calculated automatically by the meter.
Under Pythagorean proposition measurement mode, length of right side must be shorter than hypotenuse length
so that instrument can make out calculation, otherwise the instrument will display an error signal.
Under Pythagorean proposition mode, to ensure the accuracy of measurement, it must be measured from the
same starting point with a measuring order of first hypotenuse, and then the right side.
Add And Subtract Measurement:
Single distance measurement can be done through adding/subtracting to get accumulated add or subtract
operations;
Press key, and "+" appears on main measurement screen. Then enter into accumulated adding measurement
mode, accumulative value of previous measured value and the very measurement results will be displayed on the
screen.
Press key, and "-" appears on main measurement screen. Then enter into accumulated subtracting
measurement mode, where the differences between previous measured values and the new measurement
values will be displayed on the screen.

Storage and Browse
Store Measurements
Under measuring mode, as the resulting data is effective, hold down the key for 3 seconds. The measurement data
will be automatically stored into the instrument memory stick.
The unit has a maximum storage volume of 30 units.
Browse Measurements
Press key to check stored measurement data
Press key or key to browse forward or backward. Hold down the key to remove all stored records.
Tips
During operation, tip information may appear on the main display screen as follows:
Information Causes Solutions
Err 1 Signal too weak Measure target locations which are with
stronger reflecting capability
Err 2 Signal too strong Measure target locations which are
weaker reflecting capability
Err 3 Battery voltage is too low Replace battery
Err 4 Beyond working temperature Carry out measurement with the meter in
the specified scope
Err 5 Improper Measurement in Pythagorean
proposition
Re-measure, and ensure the length of
hypotenuse is longer than that of right-
side
Err 6 Memory damage Please contact Kogan.
