Warms tips:
1. As strong sunlight would weaken laser energy, which
might influence the accuracy and measuring range, so we
recommend you to avoid using in a direct sunlight. If have
to use, we kindly recommend to put a smooth and opaque
reflective plate.
2. Measurements taken through transparent objects like
glass, water, crystal etc, powerful light sources, strong
light-absorbing objects or other highly reflective surfaces
may be inaccurate. Please use our attached target card.
3. If the measurement is not accurate under normal
conditions, calibration is required. The calibration method is
as follows:
1) Turn off the device.
2) Press those four buttons ①②③④ as photo attached.
3) It will display the calibrate page, please press the
button"+/-" to calibrate the error.
4) Compare to an exact value until it is the same as the
exact value. Long press to add, short press to reduce.
