Laser Measurement

1. Single measurement
   • When the product is turned on, it will enter into the single measurement mode by default.
   • Aim the laser at the measurement target and presS ◄◄ MEAs, and the measured value will show on the screen. Press ◄◄MEAs again to take the next measurement.
2. Continuous measurement
   • Long press ◄◄MEAS to enter into the continuous measurement mode. Move the laser tape left and right or up and down. Press ◄◄MEAS to stop measuring.
3. Area measurement
   • Short pressto switch to the area measurement modeA side of theicon will flash.
   • Aim the laser at the first point of the measurement target, and press ◄◄ MeAs to measure the length of the first side (length). Then another side of the icon will flash.
   • Aim the laser at the second point, and press ◄◄MeAs again to measure the length of the second side (width). The area calculation result will be displayed at the bottom of the screen.
4. Volume measurement
   • Short pressto switch to the volume measurement mode A side of theicon will flash. Aim the laser at the first point of the measurement target, and press ◄◄MEAS to measure the length of the first side (length).
   • The second side of theicon will flash. Aim the laser at the second point, and press ◄◄MEAS again to measure the length of the second side (width).
   • Then the third side of theicon will flash. Aim the laser at the third point, and press ◄◄MEAs again to measure the length of the third side (height).
   • The volume calculation result will be displayed at the bottom of the screen.
5. Two-point Pythagorean measurement
   • Short pressto switch to the two-point Pythagorean measurement mode. A side of theicon will flash. Aim the laser at the first point of the measurement target, and press◄◄MEAS to measure the length of the first side (hypotenuse).
   • Move the laser tape to the second point which is on the same horizontal line as the first point. Press ◄◄MEAS to measure the length of the second side. The calculation result will be displayed at the bottom of the screen.

Tape Measurement

1. Movable hook
   • The movable hook is a professional design used for zero-point correction to ensure measurement accuracy.
   • Measurement method A: inside measurement
   • Take the outer surface of the hook as the base point of zero scale. The hook will move backwards and retract slightly after being supported. The retracted length is the thickness of the hook.
   • Measurement method B: outside measurement
   • Take the inner side of the hook as the base point of the zero scale. After the hook is hooked, it will move backwards slightly.
2. Magnetic hook
   • It can be attached to metal materials to measure the length.
3. Tape lock
   • Press the tape lock to draw back the tape slowly, and release it to stop drawing back.

Specifications

1. Range
   The range takes the rear reference as a reference by default. The maximum range will change according to different models and versions. The actual range is shown in the outer packaging of the product.
2. Accuracy (D is the measured length)
   • Under good measurement conditions (measurement surface, room temperature, indoor light, etc.), the rated range can be reached.
   • Under poor measurement conditions, such as excessive light, weak reflection on the surface of the measured object, or excessive temperature difference, the error will increase.
   • Note: In the case of poor sunlight or target reflection, please use a sight vane or a better reflective surface.

Troubleshooting

Code	Cause	Solution
204	Calculation error	Follow the user manual to operate again.
220	Low battery	Please replace the battery or charge the product.
255	Weak received reflected light or overlong measurement time	Improve the reflective surface (use a reflector, white paper, etc.).
256	Strong received signal	Improve the reflective surface (use a reflector, or do not aim at strong light).
261	Over Range	Please measure within the range of the product.
500	Hardware malfunction	If the same problem still occurs after turning the product on/off multiple times, please contact the dealer.
