状态。

自助校准功能主要用于修正数据，当用户测量距离发生

偏差时，可用该功能修正距离，修正范围：

-0.009~0.009m。比如用户认为偏大2mm，可将此值

调整值-0.002m，即可补偿2mm；反之偏小2mm，则

调整至0.002m。操作如下：

1.进入自助校准：关机状态下，按住 ，同时快速

短按一次 开机，屏幕显示“CAL”；

2.修改校准值：短按 ，校准值+1，校准值等于

0.009m时，再次+1，跳转至-0.009m。

The self-calibration function is mainly used to correct

data. If the deviation occurs when the user measures the

distance, this function can be used for distance correction.

The correction range is -0.009~0.009m. For example, if

the data is 2mm too large, reduce the value by 0.002m;

If the data is 2mm smaller, increase the value by 0.002m.

Operation：

1. Enter self-calibration: In the shutdown state, press and

hold the key, and at the same time quickly press

the key to start the instrument up, and the screen

displays \"CAL\"；

2. Modify calibration value: Press key to increase

the calibration value by 1. When the calibration value

is equal to 0.009m, increase the calibration value by 1

again and jump to -0.009m.

3. Save calibration value: Press to save the current

calibration value and enter the sound setting.

The instrument is equipped with sound prompt function

by default. Users can turn on/ off the sound prompt

according to their needs.

1. Enter sound setting: Refer to \"Self-calibration\" to

enter the self-calibration. Skip the step of modifying

the calibration value, save the calibration value

directly to enter the sound setting, and the screen

displays \"sound\";

2. Turn on/off sound: Press to turn the sound on or

off. \"on\" means to turn on the sound, off means to

turn off the sound;

3. Save settings: Press to save settings and return to

the state to be measured.

Pythagoras

There are two Pythagoras modes which is convenient for

indirect measurement in a specific complex environment.

Short press five times to enter Pythagoras mode:

Press , measure the length of hypotenuse (a)

Press , measure the length of one leg (b)

Device automatically calculates the length of another

leg (x)

Calculate the second leg by measuring the hypotenuse

and another leg.

Calculate the hypotenuse by measuring the length of

two legs.

Short press six times, one leg of is

blinking.

Press , measure the length of one leg (a)

Press , measure the length of another leg (b)

Device automatically calculates the length of

hypotenuse (x)

Legs must be shorter than hypotenuse, or there will be

\"err\" showed at screen. In order to guarantee the accuracy,

please make sure all measurements are started from the

same point and in the order of hypotenuse and legs.

* \"d\" indicates the actual distance.

** In harsh environment, such as: sunlight is too strong, the ambient

temperature fluctuates excessively, the reflection effect of the object's

surface is weak, the battery is low, the measurement results will have

a large error, so a reflecting plate is needed.
