  1. Accuracy can be ensured while the temperature is at 18℃ to 28℃ (64℉~82℉) and humidity is less than 80 % RH.
  2. Make sure the target is larger than the unit’s spot size. The smaller the target, the closer you should be to it. When accuracy is critical, make sure the target is at least twice as large as the spot size.
  3. If the meter used in an ambient temperature with a large temperature change, wait it at least 30 minutes to adjust it.
  4. The laser is designed for aiming only; it can be shut off while operating in short distance to save the battery.
