Attentions – There is NO protection for reverse polarity and overvoltage, please strictly follow the specification for correct
O power supply and wiring.
– The photobiological safety of this product is Class 1, so please DO NOT look straight at the lens after
N successfully connected. O – When operating this product in a dusty place, it is better to add a piece of red transparent glass or acrylic P plate over the lens for dust prevention. (905nm wavelength needs a transmittance 85%.)
– When touching this product, please wear anti-static gloves to prevent the product from failing.
– There is a risk of failure when using this product to measure high-reflective objects (such as 3M tapes) and
PONO PONO mirrors.
