Product introduction

Lithium Battery

• The built-in 3.7V 220mAh lithium battery is nonremovable.
  The instrument has its own charging circuit, with clear under voltage indication and charging indication.

• Battery charging: The charging head should be of good quality and DC5V >0.5A output. It is recommended to use the mobile phone charging head for charging.

• The instrument shall be charged in time when running out of battery or its battery symbol shows blank and flashes after being turned on due to its insufficient battery capacity. Insert USB to charge, and the battery symbol scrolls  display . When fully charged, it will display and flash.

Battery Maintenance

Keep it with full power if no operations for a long time; and charge it once every half year to avoid the battery damage.

Start the Instrument / Menu Setting

• Turn on/off the Instrument
  Turn on: Under off state, short press , device and laser get started simultaneously and the device enters the measurement mode.
  Turn off: If no operation is performed within 150s, the instrument will shut down automatically. Or long press for more than 5s to turn off it.

• Function Setting
  1. Enter baseline Settings: In the shutdown state, long press for 5s.
  2. Switch setting options: Long press for 2s to switch setting options order:【Basis Setting( ) 】-> 【 Unit Setting ( ) 】-> 【Self-Calibration ( )】-> Exit the setting and enter the testing mode.
  3. Modify the setting parameters: Press to modify the current parameter.

• Changing Reference Point
  In the basis setting state, short press to change the reference point. The default reference point is the terminal baseline.

• Unit Setting
  In the unit setting state, short press to switch the measurement unit. There are 6 units for selection.| 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
  6| 0.00 ft| 0.00 ft²| 0.00 ft³

• Self-Calibration
  To ensure the precision of the instrument, a selfcalibration function is provided.
  Calibration method: In the self-calibration state, press to adjust the self- calibration value. The default self-calibration value of the instrument is 0, when the value is adjusted to 9, then press , it will become -9, the adjustment range  is -9~9mm. After adjustment, long press 2s to save the calibration result.

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.

Single Distance Measurement

Under the test mode, press , and the instrument emits laser to lock the measuring point. Press again for single distance measurement, and the measurement result will be displayed in the major display area.

Continuous Measurement

In the testing mode, long press   for 2s to enter the continuous measurement mode. The auxiliary display area will show the maximum and minimum measurement values during the measurement process.

Area Measurement(Only SW-M30B)

In the testing mode, press once to switch to the area measurement function. The screen displays , and one side of the rectangle flashes. Follow the prompts to complete the measurements: Press to measure the first side (length); Press to  measure the second side (width); The instrument will automatically calculate the area and the result is displayed on the screen.

Volume Measurement(Only SW-M30B)

In the testing mode, press twice to switch to the volume measurement function. The screen displays , and one side of the cubic flashes.
Follow the prompts to complete the measurements:
Press to measure the first side (length);
Press to measure the second side (width);
Press to measure the third side (height);
The instrument will automatically calculate the volume and the result is displayed on the screen.

Pythagoras(Only SW-M30B)

There are four Pythagoras modes which is convenient for indirect measurement in a specific complex environment.

1. Measurement of the height of right triangle
   Under test mode, press three times to switch to the height measurement function of right triangle.
   The screen displays and the hypotenuse of triangle flashes. Follow the prompts to complete the measurements:
   Press to measure the first side a;
   Press to measure the second side b;
   The instrument will automatically calculate the height of the right triangle x, and the result will be displayed on the screen.

2. Measurement of the hypotenuse of the right triangle
   Under test mode, press four times to switch to the hypotenuse measurement function of right triangle.
   The screen shows , and the bottom edge of the triangle flashes. Follow the prompts to complete the measurements:
   Press to measure the first side a;
   Press to measure the second side b;
   The instrument will automatically calculate the hypotenuse x of the right triangle, and the result will be displayed on the screen.

3. Measurement of the height of triangular auxiliary lines
   Under test mode, press five times to switch to the height measurement function of triangle auxiliary line.
   The screen shows , and the hypotenuse of the triangle flashes. Follow the prompts to complete the measurements:
   Press to measure the first side a;
   Press to measure the second side b:
   Press to measure the third side c;
   The instrument will automatically calculate the height x of the triangular auxiliary line, and the result will be displayed on the screen.

4. Measurement of the third side of a non-right triangle
   Under test mode, press six times to switch to the function of measuring the third side of a non-right triangle. The screen shows , complete the measurement according to the prompts:
   Press to measure the side a of the triangle;
   Press to measure the height b of the triangle;
   Press to measure the other side c of the triangle;
   After the measurement, the instrument automatically calculates the third side x of the triangle, and the result is displayed on the screen.

In the state of area, volume and Pythagorean measurement state, long press to return to the straight-line distance measurement mode.

Tips

If is displayed on the screen, it indicates that the measurement failed. Press again to measure again. The error messages are shown in the following table:

reflecting plate.
Err2| Signal is too strong| Choose the surface with weaker reflection.
Err3| Low battery voltage| Charge the battery
Err4| Beyond working temperature| Use the device in the specified temperature.
Err5| Pythagoras measuring breaks the rules| Re-measure and ensure that hypotenuse is longer than legs.
Err6| Out of the measurement range| Use the device within the measurement range

Specification

Note 1: “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.

Instrument Maintenance

• The meter should not be stored in high temperature and humid environment for a long time. If it is not used very often, please place the meter in the box and store it in cool and dry place.
• Please keep the device surface clean. Use a soft wet cloth to wipe the dust on the surface. Do not use corrosive liquid to clean the device. Use the same method as wiping optical devices to wipe the meter and focusing mirror.

Packing List

Please check if all accessories are complete according to the following list.
