Parameters

Parameter Analysis

Resolution: 1mm	Laser Class: Class II
Unit: m/ft/in	Laser type: 620-670nm
Measurement time: 0.1-3s	Measurement range: 0.05-40m

Measurement accuracy: ±(2mm+5×10-5Dmm)
Operating temperature range: 0-40 degrees
Storage temperature range: -20 degrees to 60 degrees
Executive standard: GB7247.1-2012

Test Conditions

General Conditions: It refers to the strong reflection ability of the laser irradiation area.(such as painting white walls).
The background lighting is dim and the operating temperature is 15°C-35°C.At this time, an error effect of plus or minus 0.05 mm/m should be considered.
Disadvantages: Refers to the weak reflectivity of the laser-irradiated area.(Like black cardboard polished tiles.
The background lighting is strong and the working temperature is <0°C or

45°C.At this time, an error effect of plus or minus 0.15 mm/m should be considered

Instructions

Operation Precautions

The rangefinder cannot be moved during measurement, it needs to be placed on a fixed support surface
Do not block the laser emission hole and the receiving lens during measurement
Based on physical principles, errors will occur when measuring on certain surfaces, such as transparent, highly reflective, low reflective or porous surfaces.
Aiming targets can be placed on the above objects if necessary to improve measurement accuracy

Power On: Press and hold the “⑦ On/Measure key” for 3 seconds.
When the “FNIRSI” LOGO appears on the LCD display, the device is turned on

Power Off: Press and hold “⑧ Off/Clear key” for 3 second’s
When the LCD display turns off, the device is turned off.
( When there is no operation after power on : the laser will automatically turn off after 15 seconds, and it will automatically turn off after 5 minutes)

Reset: Poke the “④ Reset hole” with a toothpick and the machine will be forced to shut down.
Used to handle exceptions.

Single Measurement: Single short press “⑦ On/measure key” to start measurement.
Short press the “⑦ On/Measure key” again to get the measurement data.
The page displays up to 4 sets of measurement data.
During measurement, the straight line at the “measurement mode” turns into a dotted line, indicating that the measurement is being performed.

360° Screen Flip: Built-in gravity sensor chip, the screen can be flipped automatically.
Instructions: Long press the power button in the off state, don’t let go after power on, and enter the display interface after 3 seconds to switch the adaptive rotation function on/off.

Unit Switching: Quickly double-click with “⑦ On/Measure key” to switch the unit.
The order of unit switching is meter → feet → inch

Automatic Calibration

In the off state, press and hold the “⑧ Off/Clear key”, then press and hold the “⑦ On/Measure key” for 3 seconds, when the screen displays “CAL”, it means that
the calibration mode is entered
Short press “⑦ On/Measure key” to increase the calibration value.
Short press “⑧ Off/Clear key” to decrease the calibration value.
The calibration range is “-10mm to 10mm”. Press and hold the “⑦ On/Measure key” for 2 seconds to indicate that the calibration is complete.
Automatically enter the measurement interface

Clear Function: Short press “⑧ Off/Clear key” to cancel the last command.
A single measurement (area or volume, etc.) within the same functions.
You can use “⑧ Off/Clear key” to clear the last measurement operation and re- measure

Measurement Reference Switching
Measurement reference switching: Quickly double-click the “⑧ Off/Clear key” to switch the front and rear benchmarks.

“ ”Front benchmark: Front datum refers to the measurement starting position from the top of the device
“ ”Post benchmark: Rear datum refers to taking the bottom of the device as
the starting position for measurement, and the device defaults to the rear datum

Measurement Reference Switching

Advanced Measurement

Measurement Mode Switching: Long press the “⑦ On/Measure key” to switch the measurement mode cyclically.
The order is “Linear Measurement” → “Area Measurement” → “Volume Measurement” → “Pythagorean One” → “Secondary Pythagorean (Data Addition)” → “Secondary Pythagorean (Data Subtraction)”

Area Measurement: Click “⑦ On/Measure key”, and measure the length and width in turn.
The dotted line during measurement indicates the edge to be measured.
When all sides are measured, the system automatically calculates the area.
Advanced Measurement

Volume Measurement: Click the “⑦ On/Measure key”, and measure the length and width in turn.
The dotted line during measurement indicates the edge to be measure
When all sides are measured, the system automatically calculates the area.
Advanced Measurement

A Pythagorean: When the selection interface is not measured, the solid yellow line indicates the edge of the final calculation result.
Short press “⑦ On/Measure key” to start measurements.
The dotted line during measurement indicates the edge to be measure.
Short press again to get measurement date.
Measure the data of the right-angled base “L1” and the right-angled hypotenuse “L2” in sequence.
At the end of the measurement, the bottom edge L3 data will be automatically calculated.
Advanced Measurement

Quadratic Pythagorean(data addition): When entering the interface and not starting the measurement, the yellow solid line indicates the edge of the final calculation results.
Short press “⑦ On/Measure key” to start measurement When measuring, the dotted line indicates the edge to be measured.
Short press again to get the measurement data.
Measure the triangle hypotenuse L1 data, height L2 data, and hypotenuse L3 data in sequence.
At the end of the measurement, the bottom edge L4 data will be automatically calculated.
Advanced Measurement

Quadratic Pythagorean (data subtraction): When entering the interface and not starting the measurement, the yellow solid line indicates the edge of the final
calculation result.
Short press “measurement end will” to start the measurement, the dotted line indicates the edge to be measured during measurement.
Short press again to get measurement data.
Measure the right-angle base L1 data, L2 data and right-angle hypotenuse L3 data in sequence.
At the end of the measurement, the bottom edge L4 data will be automatically calculated.
Advanced Measurement

Bluetooth Status Indication

After power on, the Bluetooth icon at the top of the screen flashes.
After the Bluetooth connection is successful, the Bluetooth icon will no longer flash

Battery Level Indication

Battery Level Indicator: When all segments of the battery icon on the LCD display are displayed, it means the battery is fully charged.
The number of displayed segments decreases, indicating that the power is relatively reduced.
When only the battery box is displayed, it should be ready to charge in time.
When charging, the segment code will flow and the red charging indicator on the left side of the device will light up.
When the red light goes out, the battery is fully charged

Automatic Shutdown When Low Battery: When the battery is too low, the LCD display will prompt the low battery.
And countdown to shutdown
