Modes Memory Function:

The initial boot mode is RANGE mode. But any of your operations will lasts to next turn on after shut down.

Functions of "MODE" button

【1】Units switch 

The HX-800I range finder can be used to measure distances in yard or meter. The unit of measure indicators are located in the lower right portion of the LCD. 

To select yard and meter, just press and hold the “MODE” button for 3 seconds to change “Y” (yard) and “M” (meter).

 

【2】Mode switch

To switch the mode, just single-point the "MODE" button to switch the Range mode, Speed mode and Scan mode.

Range mode

【1】Look at LCD through the eyepiece,  you will see the display as below picture.

Tips:Make sure the mode switches to the Range mode, as shown in the figure below.

  

【2】Operation method

After switch to the Range mode,pressing Power button again to measure.  (The laser rangefinder will auto power-off if no operation within 8 seconds.)

Speed mode

【1】Look at LCD through the eyepiece, then single-click the "Mode" button to switch to Speed mode, you will see the display as below picture.

Tips: Make sure that the "Spd" logo is displayed on the left side of the screen, as shown in the figure below.

【2】Operation method

Single-click the"POWER"button to aim at target B and move slightly,the speed of the movement can be measured accordingly, “spd” is always displayed during measurement.

Notice：

Aiming circle should be aligned on target until aiming circle stops flash, meantime gets target’s speed.

“α”must be less than 10°, the smaller the angle, the higher the accuracy of speed.

 

Scan mode（Continuous scan）

【1】Look at LCD through the eyepiece, then single-click the "Mode" button to switch to Scan mode, you will see the display as below picture.

Tip: Make sure that the "Scan" logo is displayed on the left side of the screen, as shown in the figure below.

 

【2】Operation method

6.HOW TO WORK AND RANGING ACCURACY

The HX-800I range finder emits invisible, eye safe, infrared energy pulses. Sophisticated digital technology instantaneously calculates distances by measuring the time, which it takes for each pulse to travel from the rangefinder to the target and back to rangefinder.

The color, surface smoothness, size and sharpness of target will affect its reflectivity and range.

It is difficult to test in the following conditions and environments:

Raining or fogging / the target is too small / Low reflectivity of the measured object (black color, complex shape, curved surface, water surface, glass surface, mirror surface. etc.) / Low battery.
