DISPLAY KEYBOARD

Lithium Battery

• Built-in and non-detachable 3.7V 1000mAh Lithium battery
• Charge: Phone chargers are recommended. Please use 5V 1A chargers and Type-C charging cables to charge.
• When we can not activate instruments or there is a blank battery symbol flickering after it has been used for a period of a long time, we should charge it in time. After inserting the USB into it, the battery symbol bar scrolls to display, and when fully charged, will display and flicker.

Battery Care

Charge the instrument fully and do it every 6 months to avoid damage to batteries when the Instrument are not in use for a long time.

Power On/off And Settings

• Power on/off the instrument
  In the shutdown state, press to start the instrument and prepare to measure. In the power-on state, press and hold for 3 seconds to turn off the instrument. The instrument will be powered off automatically after 150 seconds with no operation on the instrument.

• Unit setting
  In the measurement mode, long press  to switch between different measurement units. The instrument offers 6 units to choose from.

• Units:****
  | Length| Area| Volume
  ---|---|---|---
  1| 0.000 m| 0.000 m2| 0.000 m3
  2| 0.00 m| 0.00 m2| 0.00 m3
  3| 0.0 in| 0.00 ft2| 0.00 ft3
  4| 0 1/16 in| 0.00 ft2| 0.00 ft3
  5| 0’00” 1/16| 0.00 ft2| 0.00 ft3

• Measurement Datum Settings
  Short press to switch front/middle/rear datum.  The system defaults to the rear datum.

• Backlight On/off
  The instrument`s backlight is powered on/off automatically. The instrument will open the backlight for 15 seconds after you press any keys of the instrument. And the instrument will power off the backlight to save power after 15 seconds of no operation on the instrument

Self-calibration and sound settings

To ensure the accuracy of the instrument, a self-calibration function is provided. Calibration method: In the power-off state, press and hold and at the same time until the screen shows and there are flashing numbers at the bottom. At this time, you enter the self-calibration mode. Then, the user can press to adjust the value according to the error of the instrument. The adjustment range is -9~9mm.
For example the actual distance is 3.780m
If the measured value of the instrument is 3.778m, which is 2mm lower than the actual value, you can enter the calibration mode, and press to increase the calibration value by 2mm on the existing basis press If the measured value of the instrument is 3.783m, which is 3mm higher than the actual value, you can enter the calibration mode, and  press to lower the calibration value by 3mm on the existing basis. After adjustment, press to save the calibration result.
Press to save calibration result and enter sound settings, the screen shows “sound ” and there are flashing letters at the bottom. Press to switch sound on/off, “ ” is sound on, “ is sound off. After the setting is completed, press to exit the setting.

Distance Measurement, Size, Volume And Pythagoreanindirect Measurement

• Single Measurement
  When the instrument prepared to measure, press to emit the laser, lock the measurement point. Then press again to measure single distance and the result shows in the main display area.

• Continuous Measurement
  When the instrument prepares to measure, press and hold to enter continuous measurement mode. During the continuous measurement, the maximum and minimum value and the difference between maximum and minimum show on the secondary display area.The main display area shows current measurement value, short press or exit continuous measurement mode.

• Size Measurement
  Press once, the screen shows and one side of the triangle flickers.
  Complete the following actions as prompted: Press to measure the first side(width) Press to measure the second side(length) The instrument will calculate the size automatically, and the result shows on the main display area. The secondary display area will show the measurement value of the length and width. During measurement, the user can press to clear the result and remeasure. When there is no data in the display area, press to exit size measurement mode, and enter single measurement mode.

• Volume Measurement
  Press twice, the instrument enter volume measurement mode, There will be a cube flickering on the screen.
  Complete the following actions as prompted:
  Press to measure the first side(width)
  Press to measure the second side(length)
  Press to measure the third side(height)
  The instrument will calculate the volume automatically, the calculation result shows in the main display area. And the length, width and height of the cube show in the secondary display area.
  During measurement, we can press the measurement result and remeasure. When there is no data in the display area,press to exit volume measurement mode and enter single measurement mode.

Pythagorean Measurement There are four preset modes of the instrument to measure the distance of one side or a triangle by using the Pythagorean theorem.
It is convenient for users to perform the indirect measurements in a specific complex environment.

1. Angle and height measurement Short press three times to enter angle and  height mode:
   Press to measure the length of the hypotenuse (a)  according to prompts on the screen and measure the bottom edge angle.
   The instrument automatically figures out the horizontal distance(b) and vertical distance(h)

2. Right-angled side measurement Measure the length of hypotenuse indirectly. Short press four times, the screen shows: (right-angled side flickering)Press to measure the length of one leg according to prompts on the screen (b) Press to measure the length of another side (a) Device automatically figures out the length of hypotenuse (x)

3. Short press  five times, and the screen shows (hypotenuse flickering).
   Press to measure the first side(width)
   Press to measure the second side(length)
   Press to measure the third side(height)
   The instrument will calculate the volume automatically, the calculation result shows in the main display area. And the length, width and height of the cube show in the secondary display area.
   Device automatically figures out the length of right-angled side (x)
   In Pythagorean measurement mode, the
   right-angled side must be less than the length
   of the hypotenuse before the instrument can calculate, otherwise the instrument will display an error signal prompt. In the Pythagorean measurement mode, in order to ensure the measurement accuracy, it is necessary to ensure that the measurement is from the same starting point, and the measurement is performed in the order of the hypotenuse and the right-angled side.

Data Storage Function

The measurement results are saved automatically. the user can export the recording through Apps.

Bluetooth Function

It will automatically record the data when the instrument figures out the final results. And the user can press and hold to check the recordings.Complete the following actions as prompted to check the recordings:

1. Short press to switch recordings.
2. Long press to clear all recordings.
3. Short press to exit checking recordings.

• The minimum of the range refers to the distance measured by front-end datum
• ‘ D ’ refers to actual distance
  **There will be a large error in the measurement results in harsh environments such as: strong sunlight, fluctuating temperature, weak reflectivity of reflective surface andinsufficient battery power. In this case, it is better to use the target reflector. Conditions that affect the measurement include: the objective lens or laser tube is blocked by foreign matter; the measurement target is unclear, such as water surface, glass, mirror surface; laser jitter during measurement, etc.

Daily Care

• It is forbidden to store the instrument in a high temperature and high humidity environment for a long time. When the instrument is not used for a long time, please put the instrument in the random instrument cover and store it in a cool and dry place.
• Please keep the surface of the instrument clean, wipe the dust on the surface with a damp soft cloth, and do not clean the instrument with corrosive lotion. The laser output window and its focus lens can be wiped according to maintenance procedures for optical device.
