The instrument is equipped with the self-calibration function to

ensure the accuracy of it.

Calibration method: On off state, press , then press

to turn it on. Release until \"CAL\" and a twinkling figure are

showed at the display, then the instrument enters self-calibration

mode.

At this time, user can adjust the figure by and 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 is 3.778m, 2mm smaller than the actual

value, the calibration value can be adjusted up by 2mm on the

existing basis with through the calibration function.

If the measured value is 3.783m, 3mm larger than the actual

value, the calibration value can be lowered by 3mm on the existing

basis with through the calibration function.

Finally, press to save the calibration result.

Self-calibration Function

Sound on/off

User can turn on or off the sound prompt function according to the

demand. By default, the voice prompt function is enabled. Long

press to turn off the sound prompt function. Then long press

to enable the sound prompt function.

area. Short press or to exit the continuous measurement mode.

Area Measurement

Press once, the screen will display with a flashing side.

Complete the following operations as prompted:

Press to measure the first side (width)

Press to measure the second side (length)

The instrument will automatically calculate the area, and the

results will be displayed at the major display area.

The auxiliary display area displays the measured values of the

length and width of the rectangle.

Function of Add/Subtract Accumulation

Single-segment distance measurements can be added or

subtracted accumulatively by the addition/subtraction operation.

After measuring a single distance and getting a measurement

result, the user can enter the selection of add accumulation or

subtract accumulation function by pressing the key:

Press and the screen displays \"+\" to enter the add accumulation

measurement mode. The screen displays the accumulated value

of the last measurement and the current measurement.

Press again, and the screen displays \"-\" to enter the subtract

accumulation measurement mode. The screen displays the

difference between the last measurement and the current

measurement.

Add/Subtract accumulation mode is circularly selected by

pressing .

Area accumulation: Measure the first area and get the result as

shown in Figure 1 below. Then press the key and measure

the second area. The result is as shown in Figure 2. A plus sign

will be displayed in the lower left corner. Finally, press to get

the result of two area summations, as shown in Figure 3.

Multiple add and subtract accumulation: In the add/subtract

accumulation mode, if you continue to measure multiple areas/

volumes, the instrument will automatically accumulate multiple

It is not only distance that can be added or subtracted accumulatively,

but also area and volume. The following examples illustrate the

function of add and subtract accumulation of area, and the function

of volume is similar.
