[1] Maximum ranges are typical and depend on target reflectance, environmental conditions (e.g. dust), and background radiation. Consult factory for details.

[2] At a measurement rate of 1/sec, the specified accuracy is absolute over full temperature range, a variety of materials, and any distance, with 1 standard deviation.

[3] At a measurement rate of 1/sec, this accuracy depends on limited variations in temperature, target, and range associated with the inst allation.

[4] At a measurement rate of 1/sec, under steady state conditions, within 1 standard deviation.

[5] Analog accuracy is equal to absolute or operating accuracy ±0.1% of range.

[6] Pending
