Remarks: Because the environment light intensity is too large, the ambient temperature is too high or too low, the reflector is too weak or too strong, or the target of a rough surface, different measurement objectives and measurement environment may cause some error of the measurement range or measurement results.

• ADDR Device Address

•Postion is 1, count from the top , when item is 0, count from the end (FA 04 08 01 F9),The default setting is from end

•CS check byte, it sums all the bytes in front,Returns the reverse, plus 1, in the data returned by single measurements and successive measurements, in which the quotes are part of the data,Format is ASCII sample:123.456 m display 31 32 33 2E 34 35 36 ADDR Default value  80(128)

NOTICE:

If you need to get a higher frequency, you need to sacrifice the accuracy of the measurement. When set

to 20hz (send FA 04 0A 14 E4), the accuracy in continuous measurement mode will become +-4mm; if the

frequency is set to the lowest frequency (send FA) 04 0A 00 F8), the accuracy in continuous

measurement mode will be within 1mm.

In single measurement mode (send 80 06 02 78), the accuracy is always within 1 mm.
