Conditions That can Cause Problems With the 8215/8225

Water vapor or dust can interfere with a target “seeing” its laser. The air

between the sensor heads should be visually clear. Take care to ensure that

the air between the laser heads is not being heated from steam leaks, unin-

sulated piping, etc. Heated air rising within the span between the sensor

heads can refract the laser beams and cause errors in the alignment read-

ings.

Operate the 8215/8225 ﬁxtures at ambient temperatures. If the ﬁxtures

have been stored at a different temperature than the ambient temperature,

allow the 8215/8225 ﬁxtures to reach ambient temperature. Ensure that any

heat source that may be present is not creating a large temperature differ-

ence between the 8215/8225 ﬁxtures and the ambient temperature. Sun-

light itself will not cause a laser reading problem.

Conditions such as building construction materials and contents, other

radio systems operation in the vicinity at or near the same operation fre-

quency, and noise generated by nearby equipment may make RF commu-

nication unsatisfactory. If this problem occurs, use direct cable

communications.
